no, it works on linear arrays only, as you will find in the documentation.
It seems the best optimisation strategy for your case would depend on how many individual
convolutions of what size arrays it involves.
For large arrays, as Sturla has suggested, scipy.signal.fftconvolve which does operate on multi-D arrays,
could be the best (or at least initially easiest) way to go.
