The point is precisely that, you can't do memory mapping with Npz files

The operating system can memory map any file. But as npz-files are
compressed, you will need to uncompress the contents in your memory mapping
to make sense of it.
We agree on that. The goal is to be able to create a np.memmap array
from an Npz file.
I would suggest you use PyTables instead of npz-files.
It allows on the fly compression and uncompression (via blosc) and will
probably do what you want.
Yes I know I can use other solutions. The point is that np.load silently
ignore the mmap option so I wanted to discuss ways to improve this.
