runtime error: Array shape mismatch in assignment to 'output'. Tried to match size 1 of dimension 1 of LHS with size 8 of dimension 1 of RHS.

8 |         output = upstream_grad * 2.0_real32
  |         ^^^^^^ LHS size is 1
  |
8 |         output = upstream_grad * 2.0_real32
  |                  ^^^^^^^^^^^^^ RHS size is 8
