Error using PyNEMO: operands could not be broadcast together with remapped shapes [original->remapped]: (2,2) and requested shape (0,2)

[amrtalaat4]

I've installed and activated the PyNEMO package successfully as in https://github.com/NOC-MSM/PyNEMO:

However, while I am following the tutorial to re-create the coordinates.bdy.ncfile using this command:

pynemo -s /path_to_file/PyNEMO/inputs/namelist_local.bdy

I get the following error:

File "/work/oda/as27121/pynemo_envs/pynemo/lib/python3.9/site-packages/numpy/lib/stride_tricks.py", line 348, in _broadcast_to
    it = np.nditer(
ValueError: operands could not be broadcast together with remapped shapes [original->remapped]: (2,2)  and requested shape (0,2)

Note: I've created the PyNEMO environment using the pynemo_39.yml file.

sorry @amrtalaat4 I've been on leave ... I'll have a look in the coming days and get back to you

Hi, I've run into the same issue. The full error is:

OK, this is not a bug. The issue is that the benchmark files are needed to run. If they can't be accessed, the program provides this error.

Apologies - writing some useful Error Messages into the code is on the to-do-list!
