TorchText Import Error

Hi,

I was trying to use the repo on Google Colab, but despite installing the requirements, I am getting the following error when running the run.py script.

Traceback (most recent call last):

Hi @kpriyanshu256 You can either uninstall pre-installed torchtext, or upgrade all torch, torchtext and pytorch-lightning to the latest. Be sure to restart the runtime after the (un)installation, then you should be good.

Sorry for the late reply. I was able to run the code by only installing these dependencies on Google Colab.
