Incompatiability with numpy 1.24.0

[ljlamarche]

BUG

Import fails upon new installation of pydarn in a clean environment. This appears to be due to an incompatibility with the latest version of numpy (1.24.0).

Priority

• Minor - typo, incorrect naming, fails on specific uncommon situation
• Major - misrepresentation of data, failure in a common situation
• Urgent - failure in usage, large misrepresentation

Information

python version: 3.10.8
OS: MacOS 12.6.1
matplotlib version:

Example of the bug

>>> import pydarn

AttributeError: module 'numpy' has no attribute 'str'. Did you mean: 'std'?

Attempts

Manually downgrading numpy to 1.23.0 seems to get around this problem.

Data Location

N/A

Potential Bug Location

Based on error message, potentially pydarnio/utils/conversions.py, line 42

Potential Solution(s)

• Update source code to work with the latest numpy conventions/deprecations
• Pin numpy version for installation to 1.23.0

Thanks @ljlamarche, this is actually a pyDARNio issue and can be found here: SuperDARN/pyDARNio#54

As it's open over there, I'll close the issue on this repo.
