Enable molecular property prediction, drug discovery, materials design, and biomolecule analysis through specialized neural networks, molecular featurization methods, and pretrained models.\n\n## When to Use This Skill\n\nThis skill should be used when:\n- Loading and processing molecular data (SMILES strings, SDF files, protein sequences)\n- Predicting molecular properties (solubility, toxicity, binding affinity, ADMET properties)\n- Training models on chemical\u002Fbiological datasets\n- Using MoleculeNet benchmark datasets (Tox21, BBBP, Delaney, etc.)\n- Converting molecules to ML-ready features (fingerprints, graph representations, descriptors)\n- Implementing graph neural networks for molecules (GCN, GAT, MPNN, AttentiveFP)\n- Applying transfer learning with pretrained models (ChemBERTa, GROVER, MolFormer)\n- Predicting crystal\u002Fmaterials properties (bandgap, formation energy)\n- Analyzing protein or DNA sequences\n\n## Core Capabilities\n\n### 1. Molecular Data Loading and Processing\n\nDeepChem provides specialized loaders for various chemical data formats:\n\n```python\nimport deepchem as dc\n\n# Load CSV with SMILES\nfeaturizer = dc.feat.CircularFingerprint(radius=2, size=2048)\nloader = dc.data.CSVLoader(\n    tasks=['solubility', 'toxicity'],\n    feature_field='smiles',\n    featurizer=featurizer\n)\ndataset = loader.create_dataset('molecules.csv')\n\n# Load SDF files\nloader = dc.data.SDFLoader(tasks=['activity'], featurizer=featurizer)\ndataset = loader.create_dataset('compounds.sdf')\n\n# Load protein sequences\nloader = dc.data.FASTALoader()\ndataset = loader.create_dataset('proteins.fasta')\n```\n\n**Key Loaders**:\n- `CSVLoader`: Tabular data with molecular identifiers\n- `SDFLoader`: Molecular structure files\n- `FASTALoader`: Protein\u002FDNA sequences\n- `ImageLoader`: Molecular images\n- `JsonLoader`: JSON-formatted datasets\n\n### 2. Molecular Featurization\n\nConvert molecules into numerical representations for ML models.\n\n#### Decision Tree for Featurizer Selection\n\n```\nIs the model a graph neural network?\n├─ YES → Use graph featurizers\n│   ├─ Standard GNN → MolGraphConvFeaturizer\n│   ├─ Message passing → DMPNNFeaturizer\n│   └─ Pretrained → GroverFeaturizer\n│\n└─ NO → What type of model?\n    ├─ Traditional ML (RF, XGBoost, SVM)\n    │   ├─ Fast baseline → CircularFingerprint (ECFP)\n    │   ├─ Interpretable → RDKitDescriptors\n    │   └─ Maximum coverage → MordredDescriptors\n    │\n    ├─ Deep learning (non-graph)\n    │   ├─ Dense networks → CircularFingerprint\n    │   └─ CNN → SmilesToImage\n    │\n    ├─ Sequence models (LSTM, Transformer)\n    │   └─ SmilesToSeq\n    │\n    └─ 3D structure analysis\n        └─ CoulombMatrix\n```\n\n#### Example Featurization\n\n```python\n# Fingerprints (for traditional ML)\nfp = dc.feat.CircularFingerprint(radius=2, size=2048)\n\n# Descriptors (for interpretable models)\ndesc = dc.feat.RDKitDescriptors()\n\n# Graph features (for GNNs)\ngraph_feat = dc.feat.MolGraphConvFeaturizer()\n\n# Apply featurization\nfeatures = fp.featurize(['CCO', 'c1ccccc1'])\n```\n\n**Selection Guide**:\n- **Small datasets (\u003C1K)**: CircularFingerprint or RDKitDescriptors\n- **Medium datasets (1K-100K)**: CircularFingerprint or graph featurizers\n- **Large datasets (>100K)**: Graph featurizers (MolGraphConvFeaturizer, DMPNNFeaturizer)\n- **Transfer learning**: Pretrained model featurizers (GroverFeaturizer)\n\nSee `references\u002Fapi_reference.md` for complete featurizer documentation.\n\n### 3. Data Splitting\n\n**Critical**: For drug discovery tasks, use `ScaffoldSplitter` to prevent data leakage from similar molecular structures appearing in both training and test sets.\n\n```python\n# Scaffold splitting (recommended for molecules)\nsplitter = dc.splits.ScaffoldSplitter()\ntrain, valid, test = splitter.train_valid_test_split(\n    dataset,\n    frac_train=0.8,\n    frac_valid=0.1,\n    frac_test=0.1\n)\n\n# Random splitting (for non-molecular data)\nsplitter = dc.splits.RandomSplitter()\ntrain, test = splitter.train_test_split(dataset)\n\n# Stratified splitting (for imbalanced classification)\nsplitter = dc.splits.RandomStratifiedSplitter()\ntrain, test = splitter.train_test_split(dataset)\n```\n\n**Available Splitters**:\n- `ScaffoldSplitter`: Split by molecular scaffolds (prevents leakage)\n- `ButinaSplitter`: Clustering-based molecular splitting\n- `MaxMinSplitter`: Maximize diversity between sets\n- `RandomSplitter`: Random splitting\n- `RandomStratifiedSplitter`: Preserves class distributions\n\n### 4.

MoleculeNet Benchmarks\n\nQuick access to 30+ curated benchmark datasets with standardized train\u002Fvalid\u002Ftest splits:\n\n```python\n# Load benchmark dataset\ntasks, datasets, transformers = dc.molnet.load_tox21(\n    featurizer='GraphConv',  # or 'ECFP', 'Weave', 'Raw'\n    splitter='scaffold',     # or 'random', 'stratified'\n    reload=False\n)\ntrain, valid, test = datasets\n\n# Train and evaluate\nmodel = dc.models.GCNModel(n_tasks=len(tasks), mode='classification')\nmodel.fit(train, nb_epoch=50)\n\nmetric = dc.metrics.Metric(dc.metrics.roc_auc_score)\ntest_score = model.evaluate(test, [metric])\n```\n\n**Common Datasets**:\n- **Classification**: `load_tox21()`, `load_bbbp()`, `load_hiv()`, `load_clintox()`\n- **Regression**: `load_delaney()`, `load_freesolv()`, `load_lipo()`\n- **Quantum properties**: `load_qm7()`, `load_qm8()`, `load_qm9()`\n- **Materials**: `load_perovskite()`, `load_bandgap()`, `load_mp_formation_energy()`\n\nSee `references\u002Fapi_reference.md` for complete dataset list.\n\n### 6. Transfer Learning\n\nLeverage pretrained models for improved performance, especially on small datasets:\n\n```python\n# ChemBERTa (BERT pretrained on 77M molecules)\nmodel = dc.models.HuggingFaceModel(\n    model='seyonec\u002FChemBERTa-zinc-base-v1',\n    task='classification',\n    n_tasks=1,\n    learning_rate=2e-5  # Lower LR for fine-tuning\n)\nmodel.fit(train, nb_epoch=10)\n\n# GROVER (graph transformer pretrained on 10M molecules)\nmodel = dc.models.GroverModel(\n    task='regression',\n    n_tasks=1\n)\nmodel.fit(train, nb_epoch=20)\n```\n\n**When to use transfer learning**:\n- Small datasets (\u003C 1000 samples)\n- Novel molecular scaffolds\n- Limited computational resources\n- Need for rapid prototyping\n\nUse the `scripts\u002Ftransfer_learning.py` script for guided transfer learning workflows.\n\n### 7. Model Evaluation\n\n```python\n# Define metrics\nclassification_metrics = [\n    dc.metrics.Metric(dc.metrics.roc_auc_score, name='ROC-AUC'),\n    dc.metrics.Metric(dc.metrics.accuracy_score, name='Accuracy'),\n    dc.metrics.Metric(dc.metrics.f1_score, name='F1')\n]\n\nregression_metrics = [\n    dc.metrics.Metric(dc.metrics.r2_score, name='R²'),\n    dc.metrics.Metric(dc.metrics.mean_absolute_error, name='MAE'),\n    dc.metrics.Metric(dc.metrics.root_mean_squared_error, name='RMSE')\n]\n\n# Evaluate\ntrain_scores = model.evaluate(train, classification_metrics)\ntest_scores = model.evaluate(test, classification_metrics)\n```\n\n### 8. Making Predictions\n\n```python\n# Predict on test set\npredictions = model.predict(test)\n\n# Predict on new molecules\nnew_smiles = ['CCO', 'c1ccccc1', 'CC(C)O']\nnew_features = featurizer.featurize(new_smiles)\nnew_dataset = dc.data.NumpyDataset(X=new_features)\n\n# Apply same transformations as training\nfor transformer in transformers:\n    new_dataset = transformer.transform(new_dataset)\n\npredictions = model.predict(new_dataset)\n```\n\n## Typical Workflows\n\n### Workflow A: Quick Benchmark Evaluation\n\nFor evaluating a model on standard benchmarks:\n\n```python\nimport deepchem as dc\n\n# 1. Load benchmark\ntasks, datasets, _ = dc.molnet.load_bbbp(\n    featurizer='GraphConv',\n    splitter='scaffold'\n)\ntrain, valid, test = datasets\n\n# 2. Train model\nmodel = dc.models.GCNModel(n_tasks=len(tasks), mode='classification')\nmodel.fit(train, nb_epoch=50)\n\n# 3. Evaluate\nmetric = dc.metrics.Metric(dc.metrics.roc_auc_score)\ntest_score = model.evaluate(test, [metric])\nprint(f\"Test ROC-AUC: {test_score}\")\n```\n\n### Workflow B: Custom Data Prediction\n\nFor training on custom molecular datasets:\n\n```python\nimport deepchem as dc\n\n# 1. Load and featurize data\nfeaturizer = dc.feat.CircularFingerprint(radius=2, size=2048)\nloader = dc.data.CSVLoader(\n    tasks=['activity'],\n    feature_field='smiles',\n    featurizer=featurizer\n)\ndataset = loader.create_dataset('my_molecules.csv')\n\n# 2. Split data (use ScaffoldSplitter for molecules!)\nsplitter = dc.splits.ScaffoldSplitter()\ntrain, valid, test = splitter.train_valid_test_split(dataset)\n\n# 3. Normalize (optional but recommended)\ntransformers = [dc.trans.NormalizationTransformer(\n    transform_y=True, dataset=train\n)]\nfor transformer in transformers:\n    train = transformer.transform(train)\n    valid = transformer.transform(valid)\n    test = transformer.transform(test)\n\n# 4. Train model\nmodel = dc.models.MultitaskRegressor(\n    n_tasks=1,\n    n_features=2048,\n    layer_sizes=[1000, 500],\n    dropouts=0.25\n)\nmodel.fit(train, nb_epoch=50)\n\n# 5. Evaluate\nmetric = dc.metrics.Metric(dc.metrics.r2_score)\ntest_score = model.evaluate(test, [metric])\n```\n\n### Workflow C: Transfer Learning on Small Dataset\n\nFor leveraging pretrained models:\n\n```python\nimport deepchem as dc\n\n# 1. Load data (pretrained models often need raw SMILES)\nloader = dc.data.CSVLoader(\n    tasks=['activity'],\n    feature_field='smiles',\n    featurizer=dc.feat.DummyFeaturizer()  # Model handles featurization\n)\ndataset = loader.create_dataset('small_dataset.csv')\n\n# 2. Split data\nsplitter = dc.splits.ScaffoldSplitter()\ntrain, test = splitter.train_test_split(dataset)\n\n# 3. Load pretrained model\nmodel = dc.models.HuggingFaceModel(\n    model='seyonec\u002FChemBERTa-zinc-base-v1',\n    task='classification',\n    n_tasks=1,\n    learning_rate=2e-5\n)\n\n# 4. Fine-tune\nmodel.fit(train, nb_epoch=10)\n\n# 5. Evaluate\npredictions = model.predict(test)\n```\n\nSee `references\u002Fworkflows.md` for 8 detailed workflow examples covering molecular generation, materials science, protein analysis, and more.\n\n## Example Scripts\n\nThis skill includes three production-ready scripts in the `scripts\u002F` directory:\n\n### 1. `predict_solubility.py`\nTrain and evaluate solubility prediction models. Works with Delaney benchmark or custom CSV data.\n\n```bash\n# Use Delaney benchmark\npython scripts\u002Fpredict_solubility.py\n\n# Use custom data\npython scripts\u002Fpredict_solubility.py \\\n    --data my_data.csv \\\n    --smiles-col smiles \\\n    --target-col solubility \\\n    --predict \"CCO\" \"c1ccccc1\"\n```\n\n### 2. `graph_neural_network.py`\nTrain various graph neural network architectures on molecular data.\n\n```bash\n# Train GCN on Tox21\npython scripts\u002Fgraph_neural_network.py --model gcn --dataset tox21\n\n# Train AttentiveFP on custom data\npython scripts\u002Fgraph_neural_network.py \\\n    --model attentivefp \\\n    --data molecules.csv \\\n    --task-type regression \\\n    --targets activity \\\n    --epochs 100\n```\n\n### 3. `transfer_learning.py`\nFine-tune pretrained models (ChemBERTa, GROVER) on molecular property prediction tasks.\n\n```bash\n# Fine-tune ChemBERTa on BBBP\npython scripts\u002Ftransfer_learning.py --model chemberta --dataset bbbp\n\n# Fine-tune GROVER on custom data\npython scripts\u002Ftransfer_learning.py \\\n    --model grover \\\n    --data small_dataset.csv \\\n    --target activity \\\n    --task-type classification \\\n    --epochs 20\n```\n\n## Common Patterns and Best Practices\n\n### Pattern 1: Always Use Scaffold Splitting for Molecules\n```python\n# GOOD: Prevents data leakage\nsplitter = dc.splits.ScaffoldSplitter()\ntrain, test = splitter.train_test_split(dataset)\n\n# BAD: Similar molecules in train and test\nsplitter = dc.splits.RandomSplitter()\ntrain, test = splitter.train_test_split(dataset)\n```\n\n### Pattern 2: Normalize Features and Targets\n```python\ntransformers = [\n    dc.trans.NormalizationTransformer(\n        transform_y=True,  # Also normalize target values\n        dataset=train\n    )\n]\nfor transformer in transformers:\n    train = transformer.transform(train)\n    test = transformer.transform(test)\n```\n\n### Pattern 3: Start Simple, Then Scale\n1. Start with Random Forest + CircularFingerprint (fast baseline)\n2. Try XGBoost\u002FLightGBM if RF works well\n3. Move to deep learning (MultitaskRegressor) if you have >5K samples\n4. Try GNNs if you have >10K samples\n5. Use transfer learning for small datasets or novel scaffolds\n\n### Pattern 4: Handle Imbalanced Data\n```python\n# Option 1: Balancing transformer\ntransformer = dc.trans.BalancingTransformer(dataset=train)\ntrain = transformer.transform(train)\n\n# Option 2: Use balanced metrics\nmetric = dc.metrics.Metric(dc.metrics.balanced_accuracy_score)\n```\n\n### Pattern 5: Avoid Memory Issues\n```python\n# Use DiskDataset for large datasets\ndataset = dc.data.DiskDataset.from_numpy(X, y, w, ids)\n\n# Use smaller batch sizes\nmodel = dc.models.GCNModel(batch_size=32)  # Instead of 128\n```\n\n## Common Pitfalls\n\n### Issue 1: Data Leakage in Drug Discovery\n**Problem**: Using random splitting allows similar molecules in train\u002Ftest sets.\n**Solution**: Always use `ScaffoldSplitter` for molecular datasets.\n\n### Issue 2: GNN Underperforming vs Fingerprints\n**Problem**: Graph neural networks perform worse than simple fingerprints.\n**Solutions**:\n- Ensure dataset is large enough (>10K samples typically)\n- Increase training epochs (50-100)\n- Try different architectures (AttentiveFP, DMPNN instead of GCN)\n- Use pretrained models (GROVER)\n\n### Issue 3: Overfitting on Small Datasets\n**Problem**: Model memorizes training data.\n**Solutions**:\n- Use stronger regularization (increase dropout to 0.5)\n- Use simpler models (Random Forest instead of deep learning)\n- Apply transfer learning (ChemBERTa, GROVER)\n- Collect more data\n\n### Issue 4: Import Errors\n**Problem**: Module not found errors.\n**Solution**: Ensure DeepChem is installed with required dependencies:\n```bash\nuv pip install deepchem\n# For PyTorch models\nuv pip install deepchem[torch]\n# For all features\nuv pip install deepchem[all]\n```\n\n## Reference Documentation\n\nThis skill includes comprehensive reference documentation:\n\n### `references\u002Fapi_reference.md`\nComplete API documentation including:\n- All data loaders and their use cases\n- Dataset classes and when to use each\n- Complete featurizer catalog with selection guide\n- Model catalog organized by category (50+ models)\n- MoleculeNet dataset descriptions\n- Metrics and evaluation functions\n- Common code patterns\n\n**When to reference**: Search this file when you need specific API details, parameter names, or want to explore available options.\n\n### `references\u002Fworkflows.md`\nEight detailed end-to-end workflows:\n1.

Model Selection and Training\n\n#### Quick Model Selection Guide\n\n| Dataset Size | Task | Recommended Model | Featurizer |\n|-------------|------|-------------------|------------|\n| \u003C 1K samples | Any | SklearnModel (RandomForest) | CircularFingerprint |\n| 1K-100K | Classification\u002FRegression | GBDTModel or MultitaskRegressor | CircularFingerprint |\n| > 100K | Molecular properties | GCNModel, AttentiveFPModel, DMPNNModel | MolGraphConvFeaturizer |\n| Any (small preferred) | Transfer learning | ChemBERTa, GROVER, MolFormer | Model-specific |\n| Crystal structures | Materials properties | CGCNNModel, MEGNetModel | Structure-based |\n| Protein sequences | Protein properties | ProtBERT | Sequence-based |\n\n#### Example: Traditional ML\n```python\nfrom sklearn.ensemble import RandomForestRegressor\n\n# Wrap scikit-learn model\nsklearn_model = RandomForestRegressor(n_estimators=100)\nmodel = dc.models.SklearnModel(model=sklearn_model)\nmodel.fit(train)\n```\n\n#### Example: Deep Learning\n```python\n# Multitask regressor (for fingerprints)\nmodel = dc.models.MultitaskRegressor(\n    n_tasks=2,\n    n_features=2048,\n    layer_sizes=[1000, 500],\n    dropouts=0.25,\n    learning_rate=0.001\n)\nmodel.fit(train, nb_epoch=50)\n```\n\n#### Example: Graph Neural Networks\n```python\n# Graph Convolutional Network\nmodel = dc.models.GCNModel(\n    n_tasks=1,\n    mode='regression',\n    batch_size=128,\n    learning_rate=0.001\n)\nmodel.fit(train, nb_epoch=50)\n\n# Graph Attention Network\nmodel = dc.models.GATModel(n_tasks=1, mode='classification')\nmodel.fit(train, nb_epoch=50)\n\n# Attentive Fingerprint\nmodel = dc.models.AttentiveFPModel(n_tasks=1, mode='regression')\nmodel.fit(train, nb_epoch=50)\n```\n\n### 5. MoleculeNet Benchmarks\n\nQuick access to 30+ curated benchmark datasets with standardized train\u002Fvalid\u002Ftest splits:\n\n```python\n# Load benchmark dataset\ntasks, datasets, transformers = dc.molnet.load_tox21(\n    featurizer='GraphConv',  # or 'ECFP', 'Weave', 'Raw'\n    splitter='scaffold',     # or 'random', 'stratified'\n    reload=False\n)\ntrain, valid, test = datasets\n\n# Train and evaluate\nmodel = dc.models.GCNModel(n_tasks=len(tasks), mode='classification')\nmodel.fit(train, nb_epoch=50)\n\nmetric = dc.metrics.Metric(dc.metrics.roc_auc_score)\ntest_score = model.evaluate(test, [metric])\n```\n\n**Common Datasets**:\n- **Classification**: `load_tox21()`, `load_bbbp()`, `load_hiv()`, `load_clintox()`\n- **Regression**: `load_delaney()`, `load_freesolv()`, `load_lipo()`\n- **Quantum properties**: `load_qm7()`, `load_qm8()`, `load_qm9()`\n- **Materials**: `load_perovskite()`, `load_bandgap()`, `load_mp_formation_energy()`\n\nSee `references\u002Fapi_reference.md` for complete dataset list.\n\n### 6. Transfer Learning\n\nLeverage pretrained models for improved performance, especially on small datasets:\n\n```python\n# ChemBERTa (BERT pretrained on 77M molecules)\nmodel = dc.models.HuggingFaceModel(\n    model='seyonec\u002FChemBERTa-zinc-base-v1',\n    task='classification',\n    n_tasks=1,\n    learning_rate=2e-5  # Lower LR for fine-tuning\n)\nmodel.fit(train, nb_epoch=10)\n\n# GROVER (graph transformer pretrained on 10M molecules)\nmodel = dc.models.GroverModel(\n    task='regression',\n    n_tasks=1\n)\nmodel.fit(train, nb_epoch=20)\n```\n\n**When to use transfer learning**:\n- Small datasets (\u003C 1000 samples)\n- Novel molecular scaffolds\n- Limited computational resources\n- Need for rapid prototyping\n\nUse the `scripts\u002Ftransfer_learning.py` script for guided transfer learning workflows.\n\n### 7. Model Evaluation\n\n```python\n# Define metrics\nclassification_metrics = [\n    dc.metrics.Metric(dc.metrics.roc_auc_score, name='ROC-AUC'),\n    dc.metrics.Metric(dc.metrics.accuracy_score, name='Accuracy'),\n    dc.metrics.Metric(dc.metrics.f1_score, name='F1')\n]\n\nregression_metrics = [\n    dc.metrics.Metric(dc.metrics.r2_score, name='R²'),\n    dc.metrics.Metric(dc.metrics.mean_absolute_error, name='MAE'),\n    dc.metrics.Metric(dc.metrics.root_mean_squared_error, name='RMSE')\n]\n\n# Evaluate\ntrain_scores = model.evaluate(train, classification_metrics)\ntest_scores = model.evaluate(test, classification_metrics)\n```\n\n### 8. Making Predictions\n\n```python\n# Predict on test set\npredictions = model.predict(test)\n\n# Predict on new molecules\nnew_smiles = ['CCO', 'c1ccccc1', 'CC(C)O']\nnew_features = featurizer.featurize(new_smiles)\nnew_dataset = dc.data.NumpyDataset(X=new_features)\n\n# Apply same transformations as training\nfor transformer in transformers:\n    new_dataset = transformer.transform(new_dataset)\n\npredictions = model.predict(new_dataset)\n```\n\n## Typical Workflows\n\n### Workflow A: Quick Benchmark Evaluation\n\nFor evaluating a model on standard benchmarks:\n\n```python\nimport deepchem as dc\n\n# 1. Load benchmark\ntasks, datasets, _ = dc.molnet.load_bbbp(\n    featurizer='GraphConv',\n    splitter='scaffold'\n)\ntrain, valid, test = datasets\n\n# 2. Train model\nmodel = dc.models.GCNModel(n_tasks=len(tasks), mode='classification')\nmodel.fit(train, nb_epoch=50)\n\n# 3. Evaluate\nmetric = dc.metrics.Metric(dc.metrics.roc_auc_score)\ntest_score = model.evaluate(test, [metric])\nprint(f\"Test ROC-AUC: {test_score}\")\n```\n\n### Workflow B: Custom Data Prediction\n\nFor training on custom molecular datasets:\n\n```python\nimport deepchem as dc\n\n# 1. Load and featurize data\nfeaturizer = dc.feat.CircularFingerprint(radius=2, size=2048)\nloader = dc.data.CSVLoader(\n    tasks=['activity'],\n    feature_field='smiles',\n    featurizer=featurizer\n)\ndataset = loader.create_dataset('my_molecules.csv')\n\n# 2. Split data (use ScaffoldSplitter for molecules!)\nsplitter = dc.splits.ScaffoldSplitter()\ntrain, valid, test = splitter.train_valid_test_split(dataset)\n\n# 3. Normalize (optional but recommended)\ntransformers = [dc.trans.NormalizationTransformer(\n    transform_y=True, dataset=train\n)]\nfor transformer in transformers:\n    train = transformer.transform(train)\n    valid = transformer.transform(valid)\n    test = transformer.transform(test)\n\n# 4. Train model\nmodel = dc.models.MultitaskRegressor(\n    n_tasks=1,\n    n_features=2048,\n    layer_sizes=[1000, 500],\n    dropouts=0.25\n)\nmodel.fit(train, nb_epoch=50)\n\n# 5. Evaluate\nmetric = dc.metrics.Metric(dc.metrics.r2_score)\ntest_score = model.evaluate(test, [metric])\n```\n\n### Workflow C: Transfer Learning on Small Dataset\n\nFor leveraging pretrained models:\n\n```python\nimport deepchem as dc\n\n# 1. Load data (pretrained models often need raw SMILES)\nloader = dc.data.CSVLoader(\n    tasks=['activity'],\n    feature_field='smiles',\n    featurizer=dc.feat.DummyFeaturizer()  # Model handles featurization\n)\ndataset = loader.create_dataset('small_dataset.csv')\n\n# 2. Split data\nsplitter = dc.splits.ScaffoldSplitter()\ntrain, test = splitter.train_test_split(dataset)\n\n# 3. Load pretrained model\nmodel = dc.models.HuggingFaceModel(\n    model='seyonec\u002FChemBERTa-zinc-base-v1',\n    task='classification',\n    n_tasks=1,\n    learning_rate=2e-5\n)\n\n# 4. Fine-tune\nmodel.fit(train, nb_epoch=10)\n\n# 5. Evaluate\npredictions = model.predict(test)\n```\n\nSee `references\u002Fworkflows.md` for 8 detailed workflow examples covering molecular generation, materials science, protein analysis, and more.\n\n## Example Scripts\n\nThis skill includes three production-ready scripts in the `scripts\u002F` directory:\n\n### 1. `predict_solubility.py`\nTrain and evaluate solubility prediction models. Works with Delaney benchmark or custom CSV data.\n\n```bash\n# Use Delaney benchmark\npython scripts\u002Fpredict_solubility.py\n\n# Use custom data\npython scripts\u002Fpredict_solubility.py \\\n    --data my_data.csv \\\n    --smiles-col smiles \\\n    --target-col solubility \\\n    --predict \"CCO\" \"c1ccccc1\"\n```\n\n### 2. `graph_neural_network.py`\nTrain various graph neural network architectures on molecular data.\n\n```bash\n# Train GCN on Tox21\npython scripts\u002Fgraph_neural_network.py --model gcn --dataset tox21\n\n# Train AttentiveFP on custom data\npython scripts\u002Fgraph_neural_network.py \\\n    --model attentivefp \\\n    --data molecules.csv \\\n    --task-type regression \\\n    --targets activity \\\n    --epochs 100\n```\n\n### 3. `transfer_learning.py`\nFine-tune pretrained models (ChemBERTa, GROVER) on molecular property prediction tasks.\n\n```bash\n# Fine-tune ChemBERTa on BBBP\npython scripts\u002Ftransfer_learning.py --model chemberta --dataset bbbp\n\n# Fine-tune GROVER on custom data\npython scripts\u002Ftransfer_learning.py \\\n    --model grover \\\n    --data small_dataset.csv \\\n    --target activity \\\n    --task-type classification \\\n    --epochs 20\n```\n\n## Common Patterns and Best Practices\n\n### Pattern 1: Always Use Scaffold Splitting for Molecules\n```python\n# GOOD: Prevents data leakage\nsplitter = dc.splits.ScaffoldSplitter()\ntrain, test = splitter.train_test_split(dataset)\n\n# BAD: Similar molecules in train and test\nsplitter = dc.splits.RandomSplitter()\ntrain, test = splitter.train_test_split(dataset)\n```\n\n### Pattern 2: Normalize Features and Targets\n```python\ntransformers = [\n    dc.trans.NormalizationTransformer(\n        transform_y=True,  # Also normalize target values\n        dataset=train\n    )\n]\nfor transformer in transformers:\n    train = transformer.transform(train)\n    test = transformer.transform(test)\n```\n\n### Pattern 3: Start Simple, Then Scale\n1. Start with Random Forest + CircularFingerprint (fast baseline)\n2. Try XGBoost\u002FLightGBM if RF works well\n3. Move to deep learning (MultitaskRegressor) if you have >5K samples\n4. Try GNNs if you have >10K samples\n5. Use transfer learning for small datasets or novel scaffolds\n\n### Pattern 4: Handle Imbalanced Data\n```python\n# Option 1: Balancing transformer\ntransformer = dc.trans.BalancingTransformer(dataset=train)\ntrain = transformer.transform(train)\n\n# Option 2: Use balanced metrics\nmetric = dc.metrics.Metric(dc.metrics.balanced_accuracy_score)\n```\n\n### Pattern 5: Avoid Memory Issues\n```python\n# Use DiskDataset for large datasets\ndataset = dc.data.DiskDataset.from_numpy(X, y, w, ids)\n\n# Use smaller batch sizes\nmodel = dc.models.GCNModel(batch_size=32)  # Instead of 128\n```\n\n## Common Pitfalls\n\n### Issue 1: Data Leakage in Drug Discovery\n**Problem**: Using random splitting allows similar molecules in train\u002Ftest sets.\n**Solution**: Always use `ScaffoldSplitter` for molecular datasets.\n\n### Issue 2: GNN Underperforming vs Fingerprints\n**Problem**: Graph neural networks perform worse than simple fingerprints.\n**Solutions**:\n- Ensure dataset is large enough (>10K samples typically)\n- Increase training epochs (50-100)\n- Try different architectures (AttentiveFP, DMPNN instead of GCN)\n- Use pretrained models (GROVER)\n\n### Issue 3: Overfitting on Small Datasets\n**Problem**: Model memorizes training data.\n**Solutions**:\n- Use stronger regularization (increase dropout to 0.5)\n- Use simpler models (Random Forest instead of deep learning)\n- Apply transfer learning (ChemBERTa, GROVER)\n- Collect more data\n\n### Issue 4: Import Errors\n**Problem**: Module not found errors.\n**Solution**: Ensure DeepChem is installed with required dependencies:\n```bash\nuv pip install deepchem\n# For PyTorch models\nuv pip install deepchem[torch]\n# For all features\nuv pip install deepchem[all]\n```\n\n## Reference Documentation\n\nThis skill includes comprehensive reference documentation:\n\n### `references\u002Fapi_reference.md`\nComplete API documentation including:\n- All data loaders and their use cases\n- Dataset classes and when to use each\n- Complete featurizer catalog with selection guide\n- Model catalog organized by category (50+ models)\n- MoleculeNet dataset descriptions\n- Metrics and evaluation functions\n- Common code patterns\n\n**When to reference**: Search this file when you need specific API details, parameter names, or want to explore available options.\n\n### `references\u002Fworkflows.md`\nEight detailed end-to-end workflows:\n1. Molecular property prediction from SMILES\n2. Using MoleculeNet benchmarks\n3. Hyperparameter optimization\n4. Transfer learning with pretrained models\n5. Molecular generation with GANs\n6. Materials property prediction\n7. Protein sequence analysis\n8. Custom model integration\n\n**When to reference**: Use these workflows as templates for implementing complete solutions.\n\n## Installation Notes\n\nBasic installation:\n```bash\nuv pip install deepchem\n```\n\nFor PyTorch models (GCN, GAT, etc.):\n```bash\nuv pip install deepchem[torch]\n```\n\nFor all features:\n```bash\nuv pip install deepchem[all]\n```\n\nIf import errors occur, the user may need specific dependencies.
