Error:torch.cuda.is_available() return true in cmd but return false in pycharm

I have set the right python interpreter, and there is ‘pytorch’ under the package menu. Are there any possible causes?

You are most likely using different Python environments and the one used in PyTorch might have installed the CPU-only binary.
Also, according to this topic the user claimed os.environ["CUDA_VISIBLE_DEVICES"]='1' was set somehow in Pycharm without manually setting it, which was hiding the only available GPU.
