I am trying to use LDA MAllet model. but I am facing with "No module named 'gensim.models.wrappers'" error.
I have gensim installed and ' gensim.models.LdaMulticore' works properly.
Java developer’s kit is installed
I have already downloaded mallet-2.0.8.zip and unzipped it on c:\ drive.
This is the code I am trying to use:
import os from gensim.models.wrappers import LdaMallet os.environ.update({'MALLET_HOME':r'C:/mallet-2.0.8/'}) mallet_path = r'C:/mallet-2.0.8/bin/mallet'
Does anyone know what is wrong here? Many thanks!

If you've installed the latest Gensim, 4.0.0 (as of late March, 2021), the LdaMallet model has been removed, along with a number of other tools which simply wrapped external tools/APIs.
You can see the note in the Gensim migration guide at:
If the use of that tool is essential to your project, you may be able to:
install an older version of Gensim, such as 3.8.3 - though of course you'd then be missing the latest fixes & optimizations on any other Gensim models you're using
extract the
ldamallet.pysource code from that older version & update/move it to your own code for private use - dealing with whatever issues arise
I had the same issue with Gensim's wrapper for MALLET but didn't want to downgrade. There is this new wrapper that seems to do the job pretty well.
