These days, I’m working on some text classification works, and I use
gensim=’s =doc2vec function.
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 a none
-1 digit, then it’s fine.
from gensim.models import word2vec print(word2vec.FAST_VERSION)
