无法在python中安装gensim

Question

I have problem installing gensim module. I installed numpy and scipy dependent modules successfully but was getting error while installing gensim. I tried solutions given in Python pip install gives "Command "python setup.py egg_info" failed with error code 1" but none of them worked.

Here is the error:

    >pip install --target="D:\python\packages" gensim
Collecting gensim
  Using cached gensim-2.3.0-cp36-cp36m-win32.whl
Collecting scipy>=0.18.1 (from gensim)
  Using cached scipy-0.19.1.tar.gz
    Complete output from command python setup.py egg_info:

Answer 1

The error text you've supplied indicates the actual problem is (a) involving the attempt to install scipy , on which gensim relies; (b) related to a broken HTTPS connection, indicating a problem with network connectivity (or something blocking the secure-connection).

Also, it's rare to need to specify a --target for pip ; if your environment (reachable executables) is correctly set-up, you'd be able to just do pip install gensim . (And if you are installing to a non-default location, you may have issues later when your active environment isn't using the libraries you expected.)

Suggestions:

• check that you are able to access remote secure websites, like say the homepage of the PyPI repository which pip is using: https://pypi.python.org/pypi
• try again later; perhaps the network issues were transient
• try just pip install scipy
• consider using the conda distribution tool, which tends to be well-optimized for Windows installations. (I generally prefer the miniconda variant, which installs only the minimum set of things you request.)

Also, while Python, gensim, and related packages can work on Windows systems, note that most development/testing on such Python/NLP/ML open-source happens on Linux/OSX systems. As a result, there are often extra installation/configuration issues on Windows, and then there's usually less prior-documented troubleshooting from people who've previously hit the same issues. So if you have choice, such work often goes smoothest on Linux/Unix systems.

Answer 2

You can install genism by two ways: 1. pip install -U genism

2.install easy_install then

 easy_install https://pypi.python.org/packages/source/s/setuptools/setuptools-19.2.tar.gz
