I passed the question 6，but why code does not work on the last three cells? Anybody has an idea on the error?
As you know, tests do not capture all the possible mistakes.
The suggested underlying problem is shape mismatch, more concretely your inputs do match the expected batch size (16 vs 1). I would advise to look at your Exercise 6 implementation, it could be this line:
# Add batch dimension to array. Convert from (n,) to (1, n)
It could be other things (do you use ReformerLM variable for model inside # UNQ_C6?, etc) but the thing to check (track) for, is your input/output dimensions.
