一、问题背景

       在学习Python编程使用matplotlib时,总是提示:
ModuleNotFoundError: No module named 'numpy.core._multiarray_umath'
问题大致描述如下:

D:\WorkSpace\PythonWorkSpace\Python编程-从入门到实践\venv\Scripts\python.exe D:\WorkSpace\PythonWorkSpace\Python编程-从入门到实践\part2\visable\tet.py Traceback (most recent call last):  File "D:\WorkSpace\PythonWorkSpace\Python编程-从入门到实践\venv\lib\site-packages\numpy\core\__init__.py", line 24, in <module>    from . import multiarray  File "D:\WorkSpace\PythonWorkSpace\Python编程-从入门到实践\venv\lib\site-packages\numpy\core\multiarray.py", line 10, in <module>    from . import overrides  File "D:\WorkSpace\PythonWorkSpace\Python编程-从入门到实践\venv\lib\site-packages\numpy\core\overrides.py", line 8, in <module>    from numpy.core._multiarray_umath import (ModuleNotFoundError: No module named 'numpy.core._multiarray_umath'During handling of the above exception, another exception occurred:Traceback (most recent call last):  File "D:\WorkSpace\PythonWorkSpace\Python编程-从入门到实践\venv\lib\site-packages\numpy\__init__.py", line 159, in <module>    from numpy.__config__ import show as show_config  File "D:\WorkSpace\PythonWorkSpace\Python编程-从入门到实践\venv\lib\site-packages\numpy\__config__.py", line 4, in <module>    from numpy.core._multiarray_umath import (  File "D:\WorkSpace\PythonWorkSpace\Python编程-从入门到实践\venv\lib\site-packages\numpy\core\__init__.py", line 50, in <module>    raise ImportError(msg)ImportError: IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!Importing the numpy C-extensions failed.

二、解决思路

       上述错误的原因是找不到matplotlib所在包,类似于java中的找不到依赖,基于此种原因,有两个解决思路:

首先应该确保已经正确安装呆matplotlib包,这样才能正确导入包确保项目所使用的Python编译器是我们本地安装的编译器

三、解决办法

3.1 安装matplotlib包

     安装matplotlib依赖命令如下:

python -m pip install --user matplotlib

3.2 检查项目编译器

       检查项目所使用的编译器,这一点尤为重要也很容易被我们忽略,我就是因为这一步卡了一天: 我们需要使用的是本机安装的Python编译器,不能使用项目中的编译器,如下图红框所示:
