May I ask if you have

  1. Set your PYTHONPATH to your source directoy, and
  2. If there is a file or directory named "mindspore" in current directory? Cheers.

hi @ligc , the error occurred because python take your current mindspore source dir as mindspore module path, please cd out off mindspore dir and try again.
