安装gensim步骤及遇到的问题

安装:

1. 进入http://www.lfd.uci.edu/~gohlke/pythonlibs/

2. 下载对应的版本：如python3.6，64位Windows操作系统，应该下载numpy-1.13.1+mkl-cp36-cp36m-win_amd64.whl，scipy-0.19.1-cp36-cp36m-win_amd64.whl和gensim-2.3.0-cp36-cp36m-win_amd64.whl包。

3. 安装下载包的顺序分别安装包，注意顸序丌能改变。安装命令：

    pip install gensim
    #没设置清华源的话,.直接指定清华源下载更快
    #pip install -i https://pypi.tuna.tsinghua.edu.cn/simple 模块名
    Pip install ***.whl文件

遇到问题:

1. twisted 18.7.0 requires PyHamcrest>=1.9.0, which is not installed.
   spacy 2.0.16 has requirement regex==2018.01.10, but you’ll have regex 2019.6.5 which is incompatible.
   jupyterlab-server 1.0.0 has requirement jsonschema>=3.0.1, but you’ll have jsonschema 2.6.0 which is incompatible.

解决: 下载/安装 twisted 18.7.0 requires PyHamcrest

2. 安装 Twisted-19.10.0-cp38-cp38-win_amd64的时候遇到问题 :
   ERROR: Twisted-19.10.0-cp38-cp38-win_amd64.whl is not a supported wheel on this platform.

解决1 :
List item进入python命令行,输入 :

import pip._internal
print(pip._internal.pep425tags.get_supported())

我用解决1又产生了个问题,
module ‘pip._internal’ has no attribute ‘pep425tags’
是说我python 3.x版本不能用2.x的语句,so :

解决2 :

import wheel.pep425tags as w
print(w.get_supported())
