Segmentation fault while running preprocess.py

[MehwishFatimah]

Hi,
I did installations for running this code on a cluster.
The installation specifications were same as per instructions and given below:
Python 3.5.6
Torch 1.4.0 with Cudatoolkit 10.1
Sentencepiece 0.1.3
Gensim 3.5.0
tensorboardX 1.4
I converted my data in tsv files as per given instructions.
By running preprocess.py, I got "Segmentation fault".
May you please help in this regard.
Thanks
