如何在Windows 7上安裝Gensim

Question

我有Windows 7和WinPython 3.4.3.2;試圖從http://www.lfd.uci.edu/~gohlke/pythonlibs/#gensim

我得到這個錯誤安裝Gensim：

C:\Program Files (x86)\PowerCmd>pip install e:\Python\gensim-0.12.1-cp34-none-win_amd64.whl

Answer 1

我從setup.py手動安裝https://pypi.python.org/pypi/smart_open。

有一個問題文件README.rst - 我刪除了其中的所有數據，以確保不會打印壞字符。

現在我需要手動安裝Gensim，因爲它會自動下載smart_open。不幸的是，我無法import gensim。我有以下錯誤：

ImportError: No module named 'gensim' 

但如果我執行pip install -U gensim我能看到所有的需求都已經滿足：

Requirement already up-to-date: gensim in m:\winpython-64bit-3.4.3.2\python-3.4.3.amd64\lib\site-packages\gensim-0.12.1-py3.4-win-amd64.egg

任何提示？

編輯15/08/2015：安裝成功。我只需要清理舊的嘗試並重新安裝。
