set_intersect not working with ParallelRange

[crpacheco]

Hi

Suppose I have a matrix M, a vector V and I want to intersect each row of M with V.
If I use the classic for

for i in range(M.shape[0]):
      af.set_intersect(M[i],V)

It works very well, but if I use the parallel for

for i in af.ParallelRange(M.shape[0]):
      af.set_intersect(M[i],V)

It fails with the next error message:

Invalid argument at index 1
Expected: (first_info.isVector() || first_info.isScalar())

Note: using af.broadcast instead of parallel for gives the same error message.

What can I do to solve this issue?

Thanks!

@crpacheco The output size of set operations is based on the data inside the input array. You cant run this in parallel and generate an array of a fixed size.
