Given a CuPy array a, there are two ways to get a numpy array from it: a.get() and cupy.asnumpy(a). Is there any practical difference between them? Answer cp.asnumpy is a wrapper calling ndarray.get. You can see that in the code of cp.asnumpy: As you can see (both in the documentation and in the code), cp.asn…

Cupy says it has scipy’s cg implemented, but cannot find cg(conjugate gradient method) when installed
I am unable to find this https://docs.cupy.dev/en/latest/reference/generated/cupyx.scipy.sparse.linalg.cg.html#cupyx.scipy.sparse.linalg.cg after the installation of cupy. It says module not found Can anyone help me? I don’t know what’s wrong, but I have installed cupy via pip, and this library wa…
Fastest method of bilinear weighting of a 2D point cloud onto a grid
Given a point (0.8, 0.6) and an intensity (3), one can bi-linearly “reverse interpolate” a single point onto a 2×2 grid with integer indices (0,0) -> (1,1). The points and grid are oriented with the first entry increasing downwards, and the second entry increasing towards the right. On suc…
