Error on running Encode.py: "ModuleNotFoundError: No module named 'regex'"

[samysa-kr]

I started a new installation of GPT-2 using this fork of the project, following the directions in https://www.youtube.com/watch?v=4iK-IuvatxI (for training) and https://lambdalabs.com/blog/run-openais-new-gpt-2-text-generator-code-with-your-gpu/ (for setting up the environment). This means I'm following the video instructions for training, but running everything using venv-gpt-2.

When I try
(venv-gpt-2) me@mypc:~/Finetuning/gpt-2/src$ sudo python3 encode.py training.txt training.npz

I'm getting

Traceback (most recent call last): File "encode.py", line 9, in <module> import encoder File "/home/samy/Finetuning/gpt-2/src/encoder.py", line 5, in <module> import regex as re ModuleNotFoundError: No module named 'regex'

However the package is installed, since running
(venv-gpt-2) me@mypc:~/Finetuning/gpt-2/src$ python3 -m pip install regex
returns
Requirement already satisfied: regex in /home/samy/venv-gpt-666/lib/python3.6/site-packages

The packages were installed using
(venv-gpt-2) me@mypc:~/Finetuning/gpt-2$ pip install -r requirements.txt

I can also confirm that I can run GPT-2 normally by executing interactive_conditional_samples.py on venv-gpt-2, as instructed in https://lambdalabs.com/blog/run-openais-new-gpt-2-text-generator-code-with-your-gpu/. Everything runs normally there, I get a prompt, I can give the algorithm a new seed and generate text. The only issue would be on training it with new text.

All help to solve this issue will be deeply appreciated.

I was able to overcome this on my own following instructions from https://askubuntu.com/questions/1131888/e-unable-to-locate-package-regex. The solution, apparently, was to install the package globally on my system.

sudo add-apt-repository universe (already installed in my case)
sudo apt update
sudo apt install python3-regex (for Python 3)
