No module named pyLDAvis

Question

I can't import pyLDAvis.

It is installed but for some reason, I can not import it.

I tried

conda update anaconda

pip install --upgrade pip

pip install --upgrade jupyter notebook

pip install pyLDAvis

Installing pyLDAvis returns the message 'requirement already satisfied'. So I tried uninstalling and reinstalled the package but still doesn't work. This never happened with any other packages.

How can I solve this problem?

Answer 1

The pyLDAvis gensim name changed. When I use gensim_models rather than gensim the interactive viz works.

The 'gensim_models' name is in the latest commit to bmabey's repo.

import pyLDAvis
import pyLDAvis.gensim_models as gensimvis
pyLDAvis.enable_notebook()

# feed the LDA model into the pyLDAvis instance
lda_viz = gensimvis.prepare(ldamodel, corpus, dictionary)

Answer 2

Following code worked for me and I'm using Google Colaboratory.

!pip install pyLDAvis

import pyLDAvis
import pyLDAvis.gensim_models

pyLDAvis.enable_notebook()
vis = pyLDAvis.gensim_models.prepare(ldamodel, doc_term_matrix, dictionary)
vis
