[Image removed] [image] The first picture shows my code to compute the cost function, and the second one shows the error that is displayed. The value of my cost function is nearer to the answer, but it’s not accurate. I couldn’t find the bug in the code, can someone lend me a hand.

Hi @Huvin99 , The function tf.reduce_mean already computes the mean of the tensor elements, so you don’t need to do it explicitly on your code. Also be aware of the from_logits argument needed in tf.keras.losses.categorical_crossentropy . I’m going to remove the first image on your post to prevent t…
