Problem with MNIST TF1 C1 W3

Hi,

I finished all 4 courses but I am still struggling with the 3rd Week of C1.

I got steadily the message:

But I have already it there:

I suppose it is the grader but I do not know what to do now. (I reported it in the Coursera platform but nothing) .

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

Hi, I solved it.

The grader wanted me to define the input size explicitly.

Thanks!
