C5 Week 4 Exercise 8 - AssertionError: Wrong values in translation

Course Q&A Deep Learning Specialization Sequence Models
1

All the tests have passed up to Exercise 8 - Transformer. I get an Assertion Error for the translation and I can’t figure out why. For the final_output I only use 1 line of code even though the comment says to use 2 lines. Any ideas where I could be making a mistake? Thanks.

That test tends to collect undetected errors in the Encoder and Decoder functions also.

Hi Jason,
did you manage to solve your issue? I am stuck at the same place now :slightly_frowning_face: and looking for ideas where I might be wrong.

Hi Melanie. My issue in Ex8 was caused by an error I made in one of the previous exercises. I can’t remember the exact error but it was an obvious mistake and it surprised me that the test would pass for that exercise.

Thanks for your feedback.
After searching the previous excercises I actually found my error directly in the Transformer call method. I had the wrong input arguments to the decoder. Hope this helps someone in the future.

Melanie … You are a shining Star!

Thank you very much for your hint! It helped me too.

I have the same error but even I understood my input argument is not correct. can you help??

13

I have the same error. For the inputs, I am not using the output sentence anywhere. Am I missing something?

The “wrong values in translation” error can be triggered by a number of different issues.

Update:
Yes, you should use the output sentence.
