Cannot set NUMBA_NUM_THREADS to a different value once the threads have been launched

[lboult]

Hi,

I'm having some trouble with Numba in Wake-T that seems to be to do with the Wake-T trying to set the number of NUMBA threads after they've already been initialised by another program, which in this case I think is Ocelot. This is the full error message:

RuntimeError: Cannot set NUMBA_NUM_THREADS to a different value once the threads have been launched (currently have 40, trying to set 80)

I'm wondering whether there is some workaround with setting the number of threads that Wake-T requests manually (I found mention of 'WAKET_NUM_THREADS' and tried to manually change this with os.environ but wasn't very successful).

I'm currently using numba version 0.60.0 if that is useful.

Cheers,
Lewis
