Now I'll show you how to use a pre-trained classifier to detect multiple objects in an image, and later track them across a video. 11_5 PyTorch is an optimized tensor library for deep learning using GPUs and CPUs. We revise all the layers, including dataloader, rpn, roi-pooling, etc. com/c/titanic/download/train. datasets的使用对于常用数据集,可以使用torchvision.
