ImportError: cannot import name 'get_num_classes' from 'torchmetrics.utilities.data' on step 3

Currently running the docker container on a linux environment, however when running step 3, it returns the following error:

ImportError: cannot import name 'get_num_classes' from 'torchmetrics.utilities.data' (/home/ghostdog/anaconda3/envs/talknet/lib/python3.8/site-packages/torchmetrics/utilities/data.py)

I've tried re-installing torchmetrics version 0.6.0 using the command conda install -c conda-forge torchmetrics=0.6.0
What can I do to remedy this?

hmm... it seems like the issue is with the fact that pytorch-lightning==1.3.8 is not installed during the setup, but instead a different version (fixed by simply running pip install pytorch-lightning==1.3.8)... Still getting an error though, this time:
ImportError: /home/ghostdog/anaconda3/envs/talknet/lib/python3.8/site-packages/torchtext/_torchtext.so: undefined symbol: _ZNK3c104Type14isSubtypeOfExtERKSt10shared_ptrIS0_EPSo
