Problem when importing pynldas2: No module named 'numpy.core._exceptions'

[LucRSquared]

What happened?

I don't know exactly why I am encountering this bug as I was using the module fine up to a few days ago, maybe there was a NumPy update. I currently have the version 2.0.0 installed.

I tried this in a fresh virtual environment with only pynldas2 installed with pip

If I import pynldas2 I get the following error message:

---------------------------------------------------------------------------

ModuleNotFoundError: No module named 'numpy.core._exceptions'

Line 16 of pynldas2.py tries to import a class which results in the error above:

from numpy.core._exceptions import UFuncTypeError

I went and checked and this class is indeed present under numpy -> core -> _exceptions.py so there must be a mechanism preventing the import.

I do believe I know what would fix it: If just run

numpy.core._exceptions

I get a DeprecationWarning:

DeprecationWarning: numpy.core is deprecated and has been renamed to numpy._core. The numpy._core namespace contains private NumPy internals and its use is discouraged, as NumPy internals can change without warning in any release. In practice, most real-world usage of numpy.core is to access functionality in the public NumPy API. If that is the case, use the public NumPy API. If not, you are using NumPy internals. If you would still like to access an internal attribute, use numpy._core._exceptions.
  numpy.core._exceptions

Thus this works without any issue:

from numpy._core._exceptions import UFuncTypeError

So adding a leading underscore in front of core would solve the issue.

Minimal Complete Verifiable Example

python -c "import pynldas2"

Environment

Fresh virtual environment with Python 3.11

Thanks for reporting the issue.

Yes, it's a numpy 2 compatibility issue that I've already addressed, but still haven't released a new version. So, if you update from git, it should work fine. I will release an update soon.

This is fixed in v0.17.0. Please test it out and reopen if it's not fixed.

Just tested it, it works now, thanks!
