Answer 1

Make sure you installed the Java Developers Kit (JDK).

The credit goes to this another answer

After installing the JDK, the following codes for the LDA Mallet worked like charm!

import os
from gensim.models.wrappers import LdaMallet

os.environ.update({'MALLET_HOME':r'C:/mallet/mallet-2.0.8/'})
mallet_path = r'C:/mallet/mallet-2.0.8/bin/mallet.bat'

lda_mallet = LdaMallet(
        mallet_path,
        corpus = corpus_bow,
        num_topics = n_topics,
        id2word = dct,
    )
