Quick Start

Image Classification

from deepml.tasks import ImageClassification
from deepml.fabric_trainer import FabricTrainer
import torch
from torch.optim import Adam
from torchvision.models import resnet18

# 1. Define your model
model = resnet18(num_classes=10)

# 2. Create a task
task = ImageClassification(
    model=model,
    model_dir="./checkpoints",
    classes=['cat', 'dog', 'bird', ...]  # Optional
)

# 3. Setup optimizer and loss
optimizer = Adam(model.parameters(), lr=1e-3)
criterion = torch.nn.CrossEntropyLoss()

# 4. Create trainer
trainer = FabricTrainer(
    task=task,
    optimizer=optimizer,
    criterion=criterion,
    accelerator="auto",  # Use GPU if available
    devices="auto",      # Use all available devices
    precision="16-mixed" # Mixed precision training
)

# 5. Train!
trainer.fit(
    train_loader=train_loader,
    val_loader=val_loader,
    epochs=50
)

# 6. Visualize predictions
task.show_predictions(loader=val_loader, samples=9)

Semantic Segmentation

from deepml.tasks import Segmentation
from deepml.fabric_trainer import FabricTrainer
from deepml.losses import JaccardLoss

# Define model (e.g., U-Net)
model = UNet(in_channels=3, out_channels=1)

# Create task
task = Segmentation(
    model=model,
    model_dir="./checkpoints",
    mode="binary",
    num_classes=1,
    threshold=0.5
)

# Setup training
optimizer = torch.optim.Adam(model.parameters(), lr=1e-4)
criterion = torch.nn.BCEWithLogitsLoss()

trainer = FabricTrainer(task=task, optimizer=optimizer, criterion=criterion)

# Train
trainer.fit(
    train_loader=train_loader,
    val_loader=val_loader,
    epochs=100
)
