pytorch_prac

A SPP_net in pytorch framework which could be add to CNN arch freely.

SPP layer could be added in CNN model between convolutional layer and fully-connected lay, so that you can input multi-size images into your CNN model.

The class SPPLayer in file SPP_layer.py is independent. It could be added in your own models.
