Hi everyone,

I'm encountering issues while installing WRF Python. Specifically, I'm unable to import the 'getvar' library from WRF. Could anyone please assist me?
Machine -> Apple M2
which gcc-> /usr/bin/gcc
whicg gfortran -> /opt/homebrew/bin/gfortran

The error message I'm receiving is:

ImportError Traceback (most recent call last)

2 import numpy as np
3 import xarray as xr
----> 4 from wrf import getvar
5 get_ipython().run_line_magic('matplotlib', 'widget')
6 import matplotlib.pyplot as plt
getvar error

I'm new to this environment. When attempting to install WRF-Python using the following command:

conda install -c conda-forge wrf-python

The following packages will be UPDATED:

  ca-certificates                       2023.5.7-h8857fd0_0 --> 2023.11.17-h8857fd0_0 
  certifi                             2023.5.7-pyhd8ed1ab_0 --> 2023.11.17-pyhd8ed1ab_0 
  matplotlib         pkgs/main::matplotlib-3.5.2-py39hecd8~ --> conda-forge::matplotlib-3.5.3-py39h6e9494a_2 
  openssl                                 1.1.1t-hfd90126_0 --> 1.1.1w-h8a1eda9_0 

Proceed ([y]/n)? y


However, during the process, I encountered a 'RemoveError' stating:

RemoveError: 'requests' is a dependency of conda and cannot be removed from conda's operating environment.

Similar issue here, I did not have wrf-python installed on my machine (M2 Pro). I tried all the conda installation syntaxes provided here: https://anaconda.org/conda-forge/wrf-python. I always get the PackageNotFoundError:

conda install -c conda-forge wrf-python
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

and use the search bar at the top of the page.

In last resort, I tried with pip, but still got an error (I am only including part of the message here):

     57 |     REAL(KIND=8), DIMENSION(150,150) :: PSADITMK
        |                                                1
  Warning: Array 'psaditmk' at (1) is larger than limit set by '-fmax-stack-var-size=', moved from stack to static storage. This makes the procedure unsafe when called recursively, or concurrently from multiple threads. Consider increasing the '-fmax-stack-var-size=' limit (or use '-frecursive', which implies unlimited '-fmax-stack-var-size') - or change the code to use an ALLOCATABLE array. If the variable is never accessed concurrently, this warning can be ignored, and the variable could also be declared with the SAVE attribute. [-Wsurprising]

Yeah, WRF-Python is not yet available on conda-forge for M1/M2 machines, but has gotten substantially easier to build (see my comment on #199). Hopefully, we'll get a release over there soon so it's possible to just install using conda.
