dC = torch.zeros_like(C)
for k in range(Xb.shape[0]):
dC[Xb[k]] += demb[k]
I don't know why it is `wrong.
And the correct answer is:
dC = torch.zeros_like(C)
for k in range(Xb.shape[0]):
for j in range(Xb.shape[1]):
ix = Xb[k,j]
dC[ix] += demb[k,j]

What is your question. Can you elaborate more clearly ?
