Questions about your code

[JunetaeKim]

Running your code causes two problems.

In the line, soft_dtw_distance = batch_soft_dtw(a, b, gamma=0.01, metric="L1"), the code is not executed because no warp is given.

I put a warp value and ran the code, but I had the following error message.
'('custom_gradient function expected to return', 2, 'gradients but returned', 1, 'instead.')'

I tested the code based tf 2.3 and tf_nightly 2.5, and got the same error.
