'Activation' object has no attribute 'op'

Course Q&A Deep Learning Specialization Sequence Models

Greetings!
I am trying to solve the LSTM version of emojfy assignment that is a part of the second week of course 5 of DLS.

When I create an Activation layer with ‘softmax’ as its input, I am getting the following error:
‘Activation’ object has no attribute ‘op’

Please share your full error.

I fixed that error, I think. It was missing (X) as an argument to the activation function.
Now, I am getting the following error:

Test failed 
 Expected value 

 ['LSTM', (None, 4, 128), 67072, (None, 4, 2), 'tanh', True] 

 does not match the input value: 

 ['LSTM', (None, 4, 4), 112, (None, 4, 2), 'tanh', True]

I had given the wrong number to the input argument of the LSTM layer. I have fixed it now. Thank you!

Glad to know that…~~~
