I have passed all the tests and successfully passed the submission 100/100, but in the “2.5 - Train the Model”, instead of accuracy between 90% and 100%, I have an accuracy equal to 69%.
I have already restart the kernel and rerun the notebook and even try to run locally on my computer. It’s always the same.
Could you please help?
Thanks in advance.

I’m exactly in the same weird thing with training in the 99%

I got 83%, so the unit test seems to be OK.

Please download your notebook (as a .py file, the notebook itself is too large), and sent it to me via a private message.

@padeossa, when you use the “.split()” function, are you including a “sep=…” argument?


Thank you, it really works! My accuracy now changed to 83% after I changed .split(sep=’ ') to .split() in sentence_to_avg() and sentences_to_indices() functions.

Thanks for your report.

Hi, I’m having the same problem.

Test accuracy varies between 62 to 73%.

Things I already checked:
I am not using sep=’ ’ in the split() functions.
I set embedding_layer.trainable = False in the pretrained_embedding_layer function.
I use ‘softmax’ as the activation function: Activation(‘softmax’)(X)

Any ideas?

See this:

After splitting with all the white characters(default setting of .split), my acc bumped to 83%.
