Usage

Command-Line Interface

Basic Usage

alphanetworks --train TRAIN --val VAL [OPTIONS]

Options

• --train or -t: Path to the training dataset.
• --val or -v: Path to the validation dataset.
• --epochs or -e: Number of training epochs (default: 30).
• --batch_size or -b: Batch size for training and validation (default: 32).
• --lr or -l: Initial learning rate for the Adam optimizer (default: 0.001).
• --output_dir or -o: Directory to save model weights and reports.
• --nc: Number of target classes for classification (default: inferred from data).

Help

For a detailed list of options, run:

alphanetworks --help

Examples

Example 1: Basic Training

alphanetworks --train ./data/train --val ./data/val --epochs 20

Example 2: Custom Parameters

alphanetworks --train ./data/train --val ./data/val --epochs 50 --batch_size 64 --lr 0.0005 --nc 10

---

Programmatic Usage

from alphanetworks import alphanet

# Build the model
model = alphanet(input_shape=(224, 224, 3), num_classes=10)

# Compile the model
model.compile(
    optimizer="adam",
    loss="categorical_crossentropy",
    metrics=["accuracy"]
)

# Train the model
model.fit(train_data, validation_data=val_data, epochs=30)

Troubleshooting

Download Errors

During runtime, pre-trained weights for ResNet50V2 or DenseNet169 are automatically downloaded. Ensure you have a stable internet connection.
