Hi, I’m not good at using trick for matrix multiplication.
I want to get rid of “for loop iteration” by using Pytorch functions in my code. But the formula is complicated and I can’t find a clue. Can the “for loop iteration” in the below replaced with the Torch operation?
import torch ,sys
B=10
L=20
H=5
mat_A=torch.randn(B,L,L,H)
mat_B=torch.randn(L,B,B,H)
tmp_B=torch.zeros_like(mat_B)
for x in range(L):
for y in range(B):
for z in range(B):
tmp_B[:,y,z,:]+=mat_B[x,y,z,:]*mat_A[z,x,:,:]
I’d like to know if there are any tips on how to solve this kind of problems…
