Deprecation warning with np.float, np.bool, np.complex

[ad12]

Describe the bug
Starting around v1.20, numpy has deprecated generic data types (np.float, np.bool, np.complex) in favor of standard python types (float, bool, complex). This is causing a flurry of deprecation warnings in sigpy, where default types may be any of the generic numpy dtypes.

Recommendation
Set explicit dtypes with explicit precision (e.g. np.float64 instead of np.float)

I saw that this issue was fixed in a commit on Apr 6, but unfortunately the last tagged version that is used to build the conda-forge package is from Apr 3.

When do you plan to release a version that includes the fix?

I am asking, since I am wondering if I should change the conda-forge recipe (req. numpy <=1.19).

any updates concerning a new release that includes that PR?

I suffered from the same problem, and managed to work around it by installing numpy=1.19.5 in the conda environment.

Although numpy officially deprecated np.float etc in 1.20.0, they still didn't really remove it until 1.24. You can use numpy<1.24 in your conda environment until this is fixed.
