How to fix 'C extension not loaded, training will be slow. Install a C compiler and reinstall gensim for fast training.'
anaconda prompt
conda update conda-build
==
windows 7 (32bit)
python 3.7.3
conda-build 3.18.5
gensim 3.4.0
I'm using the library node2vec, which is based on gensim word2vec model to encode nodes in an embedding space, but when i want to fit the word2vec object I get this warning:

C:\Users\lenovo\Anaconda3\lib\site-packages\gensim\models\base_any2vec.py:743:
  UserWarning: C extension not loaded, training will be slow. Install a
  C compiler and reinstall gensim for fast training.

Can any one help me to fix this issue please ?
