python安装gensim==3.5.0 版本后，import gensim 报错unable to import 'smart_open.gcs', disabling that module，网上查询后解决办法是pip install smart_open==1.10.0 ，但是安装命令报错：

AttributeError: '_NamespacePath' object has no attribute 'sort'

继续查找解决方法，原因是需要升级setuptools ，先卸载：

# pip list | grep -i setup
setuptools 28.8.0

pip uninstall setuptools==28.8.0
Found existing installation: setuptools 28.8.0
Uninstalling setuptools-28.8.0:

/usr/local/Python-3.6.1/lib/python3.6/site-packages/setuptools/*
Proceed (y/n)? y
Successfully uninstalled setuptools-28.8.0

安装新版本setuptools

pip install setuptools

然后重新安装smart_open,

pip install smart_open==1.10.0

再次执行import gensim就没有报错了

>>> import gensim
