url error occurs when installing pytorch

conda install pytorch1.6.0 torchvision0.7.0 -c pytorch behind -c pytorch can be removed. -c pytorch specifies that it will only be downloaded under the official path, so the image you set before cannot be used.

ps: If an error is reported during backpropagation, you can consider the error during forward propagation.
