Install Issues: 'get_num_classes' from 'torchmetrics.utilities.data'

[VRM1]

When installing package via the pip command, I end up getting the following error when executing from pytorch_tabular import TabularModel. I am doing a clean install and no other packages were installed prior to your package. It looks like there is some version conflict between Pytorch lightning and your package.

ImportError: cannot import name 'get_num_classes' from 'torchmetrics.utilities.data' (/Users/vineeth/anaconda3/envs/pytorchtabular/lib/python3.9/site-packages/torchmetrics/utilities/data.py).

I tried to remove the 0.9.x version of torchmetrics (that was installed by default when using your pip command) and install 0.7.x, which resolved the above issue, but now I get a different issue with the following error:

ImportError: cannot import name 'RichProgressBar' from 'pytorch_lightning.callbacks'

Could be please help me in resolving this issue?

Thanks

ImportError: cannot import name 'RichProgressBar' from 'pytorch_lightning.callbacks'

I'm assuming you are using the latest main branch from GitHub because RichProgressBar was not in any of the PyPi ones.

Which version of PyTorch Lightning are you using?

I have the same issue, and I ran the tutorial on Google Colab Pro

Update: you should try to run !pip uninstall -y torchtext before install pytorch_tabular.

@tudoanh Uninstalling torchtext doesn't work. Moreover, I am getting an error like this - `ImportError Traceback (most recent call last)

in 5 import pickle 6 tf.random.set_seed(1234) ----> 7 from torchmetrics.utilities import get_num_classes as _get_num_classes

ImportError: cannot import name 'get_num_classes' from 'torchmetrics.utilities' (/usr/local/lib/python3.7/dist-packages/torchmetrics/utilities/init.py)`

The solution is to install PyTorch Lightning through mamba / conda, and get rid of the pip dependency. pip installs an old version.

Thanks for the suggestion @NicoPiel. On Colab I tried installing Lightning using conda and I still get the original error on from pytorch_tabular import TabularModel:

ImportError: cannot import name 'get_num_classes' from 'torchmetrics.utilities.data' (/usr/local/lib/python3.7/site-packages/torchmetrics/utilities/data.py)

This confusion should be over with v1.0.* All dependencies have been upgraded
