The reason for the failure is Python No installation ModuleNotFoundError modular .

The Python package matplotlib could not be found by pyimport. Usually this means
        
that you did not install matplotlib in the Python version being used by PyCall.

resolvent ：

to update pip：python -m pip install -U pip setuptools

install matplotlib：python -m pip install matplotlib

If you use pip Slow network speed during installation , have access to pip install -i https://pypi.tuna.tsinghua.edu.cn/simple Temporarily use Tsinghua's source download .

python -m pip install -i https://pypi.tuna.tsinghua.edu.cn/simple -U pip setuptools

python -m pip install -i https://pypi.tuna.tsinghua.edu.cn/simple matplotlib
