@jhjensen2 Thanks for the bug report! Would it be possible to give us the full stack trace for the error? We will look into it

For some reason I am now getting a different error:

Same thing here!

I may be wrong, but it seems that featurizer is not featurizing... instead, it is writing a array of zeroes or something like that.

Similar to @jhjensen2 , I am trying to run the code on Google Colab.
