LDA and pLSA packages (preferably for Python)

Question

What packages for pLSA (Probabilistic Latent Semantic Analysis) and LDA (Latent Dirichlet Allocation) do you recommend for Python? Java and C++ are OK too, but Python preferred. Your experiences are highly appreciated.

There are many libs, so I don't know which to choose.

Answer 1

Gensim seems to be most popular one. It's on PyPI so, you can just install it using

sudo easy_install gensim
