Grading Issues: get_record, schema, preprocess

I’m getting a 0/10 on my get_records function. It’s pprinting the 3 records fine. Not sure what the deal is. Also, getting 5/10 on schema and preprocessing function - both appear to work fine. Submitted a dozen times with various silly tweaks, e.g. tft.mean vs tf.reduce_mean in pre-process, both work. Seeing the volume of grading errors here and various ‘fixes’ need some pro help.

Please click my name and message your notebook as an attachment.

I resolved the get_records problem - records.append…my mistake! Will message the notebook when I have it back open.

No worries. Thanks for the update. If you need help, please send the notebook in a direct message. Cheers.
