Hello. I really appreciate the explanation and codes placed in this link. However, when I try to use a training file that has 3823 rows x 65 columns (64 columns for x values x.1…x.64 and one column for y), I get: “Error in Y - output : non-conformable arrays”

I have 64 input nodes, 49 hidden nodes in one layer, and 10 outputs to get digits 0 - 9 classified in each of the proper nodes.

I am unsure why this occurs? Appreciate your help.

Thank you.
