安装时提示 ERROR: Cannot uninstall 'ruamel-yaml'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.把ruamel-yaml文件删除后还是无法安装，并且配置的pytroch环境也无法用了。请问怎样处理！
可能是因某个库或模块不匹配，导致安装失败。建议你到官网上查询相应的安装方法及安装失败问答，https://pyradiomics.readthedocs.io/en/latest/installation.html，
或通过git安装，git clone git://github.com/Radiomics/pyradiomics，cd pyradiomics，python -m pip install -r requirements.txt，python setup.py install。另外还要重新安装或升级pytorch。
