Hi,

seems I am having a basic understanding problem as I am struggeling with the shape of X.

This is X:

X = [[[[ 1.62434536, -0.61175641]

[-0.52817175, -1.07296862]

[ 0.86540763, -2.3015387 ]]

[ 0.48851815, -0.07557171]]

[ 2.18557541, -1.39649634]

[-1.44411381, -0.50446586]]]]

The notebook description mentions x.shape = (4, 3, 3, 2), which I do not fully understand.

So, we have 4 examples, each of them has 3 rows (for RGB?) with 2 columns? But what is the fourth parameter of the shape? What do the tuples in the single brackets actually stand for?

Any enlightment on my understanding problem would be highly appreciated. Thanks for your effort in advance.

Best regards,

Dan
