Week 3 Exercise 6 mean error?

Fixed by @z009LL.

A few hints for others with the same problem:

  • reduce_mean, as its name suggests, already computes the mean.
  • y_pred and y_true should have shape (number of examples, num_classes) .
  • Make sure you’re passing the right parameters to categorical_crossentropy.
  • [Update] There is no need to set label_smoothing, which is a regularization parameter.

Good luck with the rest of the specialization :slight_smile:
