好像是python 3.7不支持，尝试改成3.6.4

Please note and check the following:
  * The Python version is: Python3.6 from "D:\software\Anaconda3\envs\NER\python.exe"
  * The NumPy version is: "1.19.4"
and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.
Original error was: No module named 'numpy.core._multiarray_umath'

然后又要改numpy为 1.16.0
