pytorch-mighty

The Mighty Monitor Trainer for your pytorch models. Powered by Visdom.

Documentation: https://pytorch-mighty.readthedocs.io/en/latest/

Installation

Requires Python 3.6+

1. Install PyTorch:
   • CPU backend: conda install pytorch torchvision cpuonly -c pytorch
   • GPU backend: conda install pytorch torchvision cudatoolkit=10.2 -c pytorch
2. $ pip install pytorch-mighty

Quick start

Before running any script, start Visdom server:

$ python -m visdom.server -port 8097

Then run python examples.py or use the code below:

import torch
import torch.nn as nn
from torchvision import transforms
from torchvision.datasets import MNIST

from mighty.models import MLP
from mighty.monitor.monitor import MonitorLevel
from mighty.trainer import TrainerGrad
from mighty.utils.data import DataLoader

model = MLP(784, 128, 10)

optimizer = torch.optim.Adam(model.parameters(), lr=1e-3)
scheduler = torch.optim.lr_scheduler.ReduceLROnPlateau(optimizer)

data_loader = DataLoader(MNIST, transform=transforms.ToTensor())

trainer = TrainerGrad(model,
                      criterion=nn.CrossEntropyLoss(),
                      data_loader=data_loader,
                      optimizer=optimizer,
                      scheduler=scheduler)
# trainer.restore()  # uncomment to restore the saved state
trainer.monitor.advanced_monitoring(level=MonitorLevel.SIGNAL_TO_NOISE)
trainer.train(n_epochs=10, mutual_info_layers=0)

Finally, navigate to http://localhost:8097 to see the training progress.
