Python问题：Original error was: No module named ‘numpy.core._multiarray_umath‘

1.Numpy版本不对

键盘win+R ——出现运行窗口——输入cmd——回车键

C:\Users\DELL>pip show numpy
输入pip show numpy 显示numpy版本

升级numpy版本，出现错误：pip版本太低

C:\Users\DELL>pip install --upgrade numpy
Looking in indexes: https://pypi.tuna.tsinghua.edu.cn/simple
Requirement already satisfied: numpy in d:\python\lib\site-packages (1.22.0)
WARNING: You are using pip version 21.3.1; however, version 22.0.3 is available.
You should consider upgrading via the 'D:\python\python.exe -m pip install --upgrade pip' command.
升级pip版本

C:\Users\DELL>python -m pip install -U pip

查看pip版本，升级成功

C:\Users\DELL>pip show pip

先卸载原先的numpy（为了能使numpy升级）

C:\Users\DELL>pip uninstall numpy

pip重新安装numpy

C:\Users\DELL>pip install -i https://pypi.tuna.tsinghua.edu.cn/simple numpy

用升级后的pip升级numpy

C:\Users\DELL>pip install --upgrade numpy
