ModuleNotFoundError: No module named 'numpy.core._multiarray_umath'

I haven't had this problem before, and suddenly I can't run

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy c-extensions failed.

• Try uninstalling and reinstalling numpy.
• If you have already done that, then:

1. Check that you expected to use Python3.8 from "/public/home/users/caep003/DP_ZHANG/deepmd-kit/bin/python",
   and that you have no directories in your PATH or PYTHONPATH that can
   interfere with the Python and numpy version "1.17.2" you're trying to use.
2. If (1) looks fine, you can open a new issue at
   https://github.com/numpy/numpy/issues. Please include details on:

• how you installed Python

• how you installed numpy

• your operating system

• whether or not you have multiple versions of Python installed

• if you built from source, your compiler versions and ideally a build log

• If you're working with a numpy git repository, try git clean -xdf
  (removes all files not under version control) and rebuild numpy.

Note: this error has many possible causes, so please don't comment on
an existing issue about this - open a new one instead.

Original error was: No module named 'numpy.core._multiarray_umath'

I don't know what your Python version is, but it is obvious that you're mixing python 3.8 deepmd-kit with python 3.7 numpy. Please check your environment variables or consider reinstalling them.
