Kindle - Making a PyTorch model easier than ever!

Kindle - Making a PyTorch model easier than ever!

Documentation

Kindle is an easy model build package for PyTorch. Building a deep learning model became so simple that almost all model can be made by copy and paste from other existing model codes. So why code? when we can simply build a model with yaml markup file.

Kindle builds a model with yaml file which its method is inspired from YOLOv5.

Usage

Build a model

1. Make model yaml file

• Example model https://pytorch.org/tutorials/beginner/blitz/cifar10_tutorial.html

input_size: [32, 32]
input_channel: 3

depth_multiple: 1.0
width_multiple: 1.0

backbone:
    [
        [-1, 1, Conv, [6, 5, 1, 0], {activation: LeakyReLU}],
        [-1, 1, MaxPool, [2]],
        [-1, 1, nn.Conv2d, [16, 5, 1, 2], {bias: False}],
        [-1, 1, nn.BatchNorm2d, []],
        [-1, 1, nn.ReLU, []],
        [-1, 1, MaxPool, [2]],
        [-1, 1, Flatten, []],
        [-1, 1, Linear, [120, ReLU]],
        [-1, 1, Linear, [84, ReLU]],
    ]

head:
  [
      [-1, 1, Linear, [10]]
  ]

2. Build the model with kindle
