pytorch_modules

Introduction

A neural network toolkit built on pytorch/opencv/numpy that includes neural network layers, modules, loss functions, optimizers, data loaders, data augmentation, etc.

Features

• Advanced neural network modules/loss functions/optimizers
• Ultra-efficient trainer and dataloader that allows you to take full advantage of GPU

Installation

sudo pip3 install pytorch_modules

or

sudo python3 setup.py install

Usage

pytorch_modules.utils

Includes a variety of utils for pytorch model training. See woodsgao/pytorch_segmentation as a tutorial.

pytorch_modules.nn

This module contains a variety of neural network layers, modules and loss functions.

import torch
from pytorch_modules.nn import ResBlock

# NCHW tensor
inputs = torch.ones([8, 8, 224, 224])
block = ResBlock(8, 16)
outputs = block(inputs)

pytorch_modules.backbones

This module includes a series of modified backbone networks.

import torch
from pytorch_modules.backbones import ResNet

# NCHW tensor
inputs = torch.ones([8, 8, 224, 224])
model = ResNet(32)
outputs = model.stages[0](inputs)

pytorch_modules.datasets

This module includes a series of dataset classes integrated from pytorch_modules.datasets.BasicDataset which is integrated from torch.utils.data.Dataset . The loading method of pytorch_modules.datasets.BasicDataset is modified to cache data with LMDB to speed up data loading. This allows your gpu to be fully used for model training without spending a lot of time on data loading and data augmentation. Please see the corresponding repository for detailed usage.
