Install sigpy under Ubuntu 22.04 (np.float and co)

[m-a-x-i-m-z]

I'm trying to install sigpy under the current Ubuntu LTS version using pip but seem to be stuck:

1: the current version in the pip repository (0.1.25) seems to still suffer from the np.float problem
2: trying to downgrade numpy fails seemingly due to the compiler incompatibility
3: trying to run pip directly from git produces an error (see below). Probably something is not right in pyproject.toml ...

To Reproduce

1: pip install sigpy
most functions would then fail due to the no.float problem.

2: does not concern this project so much so I leave it out

3: pip install 'sigpy@git+https://github.com/mikgroup/sigpy.git'

Defaulting to user installation because normal site-packages is not writeable

This was reported several times (e.g. #123, #124), but the issues get closed without releasing the fix 😞

Would be really great if you could take care of this!

Just got added as a sigpy maintainer and resolved with version 0.1.26
