Import fails with 'ValueError: numpy.ndarray size changed'

[suessspeise]

During the import of the module this error occurs:

File ~/.local/lib/python3.10/site-packages/climt/_components/berger_solar_insolation.py:4
      2 import logging
      3 try:
----> 4     from ._berger_solar_insolation import get_solar_parameters, get_orbital_parameters
      5 except ImportError:
      6     logging.warning(
      7         'Import failed. Insolation is likely not compiled and will not be '
      8         'available.'
      9     )

File ~/.local/lib/python3.10/site-packages/climt/_components/_berger_solar_insolation.pyx:1, in init climt._components._berger_solar_insolation()

ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject

See this notebook.

What process did you use for installing konrad. Did you install the full climt or just RRTMG?

[suessspeise]

I used pip install konrad. I installed neither climt nor RRTMG explicitly. I added the output of pip freeze to the notebook. RRTMG does not appear there, climt does.

climt==0.16.25

Did you update the environment afterwards? Some parts of climt are very picky about the installed NumPy version which could lead to your issue in case your numpy version got updated at some point.

Setting up a new environment using the provided environment.yaml solved the problem. Sorry for the fuss and thanks for the support!
