Gensim taps into these low-level BLAS libraries, by means of its dependency on NumPy. Many scientific algorithms can be expressed in terms of large matrix operations (see the BLAS note above). How come gensim is so fast and memory efficient? Isn’t it pure Python, and isn’t Python slow and greedy? Support for Python 2.7 was dropped in gensim 4.0.0 – install gensim 3.8.3 if you must use Python 2.7. Gensim is being continuously tested under all supported Python versions.

Or, if you have instead downloaded and unzipped the source tar.gz package: python setup.py installįor alternative modes of installation, see the documentation. Install the latest version of gensim: pip install -upgrade gensim On OSX, NumPy picks up its vecLib BLAS automatically, so you don’t need to do anything special. This is optional, but using an optimized BLAS such as MKL, ATLAS or OpenBLAS is known to improve performance by as much as an order of magnitude.

It is also recommended you install a fast BLAS library before installing NumPy. You must have them installed prior to installing gensim. This software depends on NumPy and Scipy, two Python packages for scientific computing. If this feature list left you scratching your head, you can first read more about the Vectorĭocument analysis on Wikipedia.
