Hi Mathieu,
Thank you for taking the time to help me.

Yes, we have demos of TF-DF in TFX, but we have yet to publish it :).

I’m looking forward to these demos!
I have been working on this on and off for the past few days and am still running into some issues. I am able to successfully run the entire pipeline when all features are Tensor objects, but have issues when they are SparseTensor objects despite transforming them. I am still investigating this, but wanted to check if it is known that sparse tensors need to be handled specially.
Thank you,
Ryan
