How to load array from the disk, such as in the format of '.npy' ?

[WangYun1995]

Hi,
I find that mpi4py-fft is an excellent tool for performing the FFT in parallel, which greatly improves computational efficiency. However, I don't see anything in the documentation about how to load data from the disk. So, Can you specify the methods of loading data from the disk?

Hi
Since the arrays mpi4py are working on are numpy arrays that have been distributed, we use hdf5 or netcdf for IO. See https://mpi4py-fft.readthedocs.io/en/latest/io.html.
