Closed landmanbester closed 6 months ago

landmanbester commented 6 months ago

Is there a way to do

x[...] = y.T

using numexpr? From the answer given here

https://stackoverflow.com/questions/67431966/how-to-avoid-huge-overhead-of-single-threaded-numpys-transpose

I believe there might be something to gain using numexpr for this purpose
