microflame 0.1.0

A minimal PyTorch training loop with checkpointing, resuming, and plotting built in.

microflame

A minimal PyTorch training loop — checkpointing, resuming, and plotting built in.

Install

pip install microflame

Quickstart

from torch import nn
from torch.optim import Adam
from microflame import Trainer

model = nn.Sequential(nn.Flatten(), nn.Linear(28 * 28, 128), nn.ReLU(), nn.Linear(128, 10))

trainer = Trainer(
    train_dataloader=train_loader,
    val_dataloader=val_loader,
    model=model,
    loss_fn=nn.CrossEntropyLoss(),
    optimizer=Adam(model.parameters(), lr=1e-3),
)

trainer.fit(num_epochs=10, save_path="checkpoint.pth", save_frequency=5)
trainer.plot()

Resume from a checkpoint:

trainer.resume("checkpoint.pth", num_epochs=20)

Features

• Automatic device selection (CUDA → MPS → CPU)
• Training + validation loop with live tqdm progress and per-epoch metrics
• Loss/accuracy history tracking
• Checkpoint save/load (model, optimizer, scheduler, history)
• Resume training from a checkpoint
• One-line loss/accuracy plots via matplotlib
