rtf_checkpoints bug when fitting the GeoValidator example model

[martinjurkovic]

Running the REaLTabFormer_GeoValidator_Example.ipynb on Google Colab results in the following error during the rtf_model.fit(data, num_bootstrap=10):

/usr/local/lib/python3.10/dist-packages/realtabformer/realtabformer.py:834: UserWarning: No best model was saved. Loading the closest model to the sensitivity_threshold.

I get the same error when fitting a different dataset on my local machine (MAC OS, python 3.10.13).

The problem seems to be the latest version of the transformers library, since reverting to transformers==4.24.0 (from pyproject.toml) fixes the problem.
