I’m stuck on Exercise 6 of the TensorFlow Introduction assignment, where I need to calculate the total cost given the model’s predictions and the true labels. I am using the pescribed functions, tf.reduce_sum() and tf.keras.losses.categorical_crossentropy(from_logits=True), but it still gives the w…

Code does not correctly calculate cost despite the code seeming right

Glad to hear that you solved it. They did mention the expected dimensions of the labels and logits in the instructions, although they did not actually use the word “transpose” anywhere. I explained the background on the other thread that I linked above.
