如何在 Windows 7 上安装 Gensim

Question

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

安装 Gensim

我收到这个错误：

C:\Program Files (x86)\PowerCmd>pip install e:\Python\gensim-0.12.1-cp34-none-win_amd64.whl
You are using pip version 6.0.8, however version 7.1.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Answer 1

错误消息表明，这可能是 Python3 'on windows' 兼容性错误。

Answer 2

我从 setup.py.

手动安装了 https://pypi.python.org/pypi/smart_open

文件有问题README.rst - 我删除了其中的所有数据，以确保不会打印出错误字符。

现在我需要手动安装 Gensim，因为它会自动下载 smart_open。不幸的是，我无法 import gensim。我遇到以下错误：

ImportError: No module named 'gensim'

但是如果我执行 pip install -U gensim 我可以看到所有要求都已满足：

有什么提示吗？

编辑 15/08/2015：安装成功。我只需要清理旧的尝试并重新安装。
