unable to generate the vmap

[rkoystart]

I have successfully generated the phrase_table.gz using the command

sudo docker run -v $(pwd):/root/corpus build-pt train en pt 3 > phrase-table.gz

Now with the generated phrase_table.gz i am trying the generate the vmap with the following command

python build-vmap.py -pt phrase-table.gz -ms 3 -mf 2 -km 20 -tv target_vocabulary -zg zg_list > vmap

I am getting the following error

Traceback (most recent call last):
  File "build-vmap.py", line 46, in <module>
    entries = line.split(" ||| ")
TypeError: a bytes-like object is required, not 'str'

And when i try to print the first few lines in phrase_table.gz

I think the script still requires Python 2 at this time.

Ok , will try it in python 2.

Trying in python2 worked successfully. Thanks @guillaumekln
