RuntimeError: implement_array_function method already has a docstring

最近开始学习matplotlib，在pycharm中安装运行代码后提示

 RuntimeError: implement_array_function method already has a docstring

网上找资料，执行了

pip install numpy
pip install scipy
pip install pandas
pip install matplotlib
pip install scikit-learn

更换了安装源，发现只有清华的，才能找到scikit-lenrn
问题依旧
再找资料，发现有人将matplotlib的版本由3.2.1降为3.0.3解决，
pip uninstall matplotlib
pip install matplotlib==3.0.3
顺利解决！！
