Gensim needs a C compiler?

Sorry I don't have enough reputation to post images.

The main problem is that it tells me that I need to install the C compiler and reinstall gensim, or the train is going to be slow and it is actually very slow.

I installed mingw32, Visual Studio 2008 and added mingw32 environment variable to my path.

Any ideas on how to solve it?

Just like you installed mingw32 and added MinGW\bin

to my variable PATH

. Then I uninstalled gensim with pip uninstall gensim

and tried reinstalling with pip install gensim

. This, however, gave the same warning, so I downloaded gensim-0.12.3.tar.gz

from here instead . I unpacked the archive as well as the internal one, opened a cmd window in the folder and ran python setup.py install

gensim to install. Now I could already see that he can see the MinGW installation. It installed correctly and I could run gensim without warning and much faster.

Similar to user1151923, after adding the MinGW\bin

path to my variable and uninstalling / reinstalling gensim via pip, I still got the same warning. I'll fix the following code to fix this issue (installed gensim from conda).

pip uninstall gensim



conda install gensim

I had the same problem and tried many solutions, but none of them worked, other than switching to gensim version 3.7.1.
