Which version of scipy is numba-scipy currently most compatible with?

Numba numba-scipy

@sschaer Thanks alot, nice to see there are other approaches, though C++ has been a bit outside of my knowledge. I could not run the code on my set-up (/bin/sh: 1: g++: not found, detailed below), but it runs fine on Google Colab.

  1. What would I need in order to get around the error?
Details on (`/bin/sh: 1: g++: not found`)

On my setup, this line:

gpp_make_shared(src, "cyl_bessel_k.cpp")

Produces this message:

  1. Also: I plan on running the scalar-input version of kv on several workers in parallel. Regarding this, I have an obstacle detailed here:. If you have any experience with running ctypes.CFUNCTYPE.<locals>.CFunctionType then I would be very interested in your take on this.
