WebMay 27, 2024 · But the skimage view_as_blocks (used by block_reduce) ignores the array subclassing, producing a regular array (without mask). So the masking has to be applied to this blocked array, e.g. with a function like: lambda arr,axis:np.ma.masked_equal (arr,0).mean (axis). Look at the code for block_reduce. – hpaulj May 27, 2024 at 16:33 … WebCuPy is an open-source array library for GPU-accelerated computing with Python. CuPy utilizes CUDA Toolkit libraries including cuBLAS, cuRAND, cuSOLVER, cuSPARSE, cuFFT, cuDNN and NCCL to make full use of the GPU architecture. The figure shows CuPy speedup over NumPy. Most operations perform well on a GPU using CuPy out of the box.
