报错： ImportError: cannot import name ‘soft_unicode‘ from ‘markupsafe‘
解决方法：
在 terminal 中运行：
pip3 install --force-reinstall MarkupSafe==2.0.1
python3.8使用scikit-learn0.20.2时报错TypeError: an integer is required (got type bytes)
【sklearn版本0.20】在报错信息中找到图示中文cloudpickle所在目录。打开对应文件后切换到148行左右
未修改的代码长这样：

在else:后面开始修改，改为：
