Tensorflow map_fn, from the docs, map on the list of tensors unpacked from elems on dimension 0. in this case, the only axis of the input tensor [1,2,3], or [-1,1,-1]. Operations are thus 1*-1,2*1 and 3*-1, and the results are repacked giving you the tensor shape. share. 2021-04-06 · Mapping functions with single-Tensor inputs and outputs.

There seems to be a problem with y_pred. Reason: On iterating, tf.map_fn() returned elements of (None, 1) and slicing too returns this extra 1 at the end which is (None, None, 1). And this happens only with y_pred and not with y_true. Question: So, what's actually wrong with y_pred?
