Issue with text_classification_classical_text_explainer.ipynb

[fatosismali]

When executing the following cell:
classifier, best_params = explainer.fit(X_train, y_train)

It results with the following error:
ValueError: empty vocabulary; perhaps the documents only contain stop words

Using the same data set as in the example notebook - haven't changed anything in the code.

I had a similar issue, using an older version of spacy (2.3.7) package on pypi fixed it, looks like the tokenizer code needs to be updated to latest spacy

Hi... Is the issue solved? Am facing the same error ValueError: empty vocabulary; perhaps the documents only contain stop words. When trying to use explainer.fit(text_train, y_train_encoded) for classification.
