'DataSelector' object has no attribute 'ft_term_dist_'

[nilsblessing]

Hello everyone,

I tried to run the example shown in the colab guide and faced the following error:

AttributeError: 'DataSelector' object has no attribute 'ft_term_dist_'

It occured when running the following command:

selected_corpus = selector.transform(training_texts)

(I didn't execute it via colab but via Microsoft Azure using Databricks)

Any idea why this happens?

Best
Nils
