torchplate 0.0.2

A minimal and simple machine learning experiment module for PyTorch.

torchplate: Minimal Experiment Workflows in PyTorch

(Github | PyPI | Documentation)

An extremely minimal and simple experiment module for machine learning in PyTorch.

In addition to abstracting away the training loop, we provide several abstractions to improve the efficiency of machine learning workflows with PyTorch.

Example

To get started, create an experiment child class of torchplate.experiment.Experiment and provide several key, experiment-unique items: model, optimizer, and a training set dataloader. Add whatever custom methods you may want to this class. Then starting training! That's it!

import torchplate
import data 
import models
import torch
import torch.optim as optim
import torch.nn as nn


class SampleExp(torchplate.experiment.Experiment):
    def __init__(self): 
        self.model = models.Net()
        self.optimizer = optim.Adam(self.model.parameters(), lr=0.001)
        self.criterion = nn.CrossEntropyLoss()
        dataset = data.load_set('cifar')
        # use various torchplate.utils to improve efficiency of common workflows 
        self.trainloader, self.testloader = torchplate.utils.get_xy_loaders(dataset)

        # inherit from torchplate.experiment.Experiment and pass in
        # model, optimizer, and dataloader 
        super().__init__(
            model = self.model,
            optimizer = self.optimizer,
            trainloader = self.trainloader 
        )
    
    # provide this abstract method to calculate loss 
    def evaluate(self, batch):
        x, y = batch
        logits = self.model(x)
        loss_val = self.criterion(logits, y)
        return loss_val


exp = SampleExp()
exp.train(num_epochs=5)
