These days, I’m working on some text classification works, and I use
When using gensim, it shows this warning message:
C extension not loaded for Word2Vec, training will be slow.
I search this on Internet and found that gensim has rewrite some part of the code using
cython rather than
numpy to get better performance. A compiler is required to enable this feature.
I tried to install mingw and add it into the path, but it’s not working.
Finally, I tried to install Visual C++ Build Tools and it works.
If this output is not
-1, then it’s fine.
from gensim.models import word2vec print(word2vec.FAST_VERSION)
