In pytorch, what is the difference between indexing with square brackets and "index_select"?
Say there are two pytorch tensors a, which is float32 with shape [M, N], and b, which is int64 with shape [K]. The values in b are within [0, M-1], so the following line gives a new tensor c indexed by b:
c = a[b] # [K, N] tensor whose i-th row…
