TypeError: expected str, bytes or os.PathLike object, not _io.BufferedReader in mallet

Question

I followed the tutorial here for mallet https://www.youtube.com/watch?v=TgXLq1XIdA0&t=823s. However, I get this error after running the python script.

Traceback (most recent call last):
  File "tm.py", line 38, in <module> 
    lda_model = gensim.models.wrappers.ldamallet.LdaMallet(

    self.train(corpus)

TypeError: expected str, bytes or os.PathLike object, not _io.BufferedReader

The error was during the creation of the lda_mallet model.

mallet_path = os.path.join('C:\mallet','bin','mallet')

# create the mallet modeling object
lda_model = gensim.models.wrappers.ldamallet.LdaMallet(
    mallet_path,
    corpus=processed_corpus,
    id2word=corpus_dictionary,
    num_topics=number_of_topics,
    optimize_interval=10,
    prefix='fed_'
)

I fixed my own error. I created a new environment in anaconda and install gensim and other required libraries. It works!
