Answer: The problem cause by  Use latest version of PyTorch (too new) Use latest version of conda (No support NumPy what PyTorch 1.11.0 need), then run Python from conda's virtual environment.  Solution:  Download Python 3.10.4 at https://www.python.org/ Install PyTorch like the command in the question, instlal Jupyter notebook. No use conda, Anaconda Navigator.  Everything will no problem.
