No such file or directory: gtexfix_comments

Hello Dmitry. Your project is very interesting, but I can't use it.
When I run ./to.py.file.tex I get the message: "The input should be .txt file. Exit."
So I change the extension to txt and run ./to.py file.txt and get a bigger message:
Input file: text.txt
Traceback (most recent call last):
File "/home/usu/Downloads/./to.py", line 24, in
with open ('gtexfix_comments', 'rb') as fp:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
FileNotFoundError: [Errno 2] No such file or directory: 'gtexfix_comments'
