AttributeError: 'function' object has no attribute 'implementation'

Hi everyone,

I've tried to execute the Minibackend notebook, but I've got the following error when trying to import a module from openeo_processes_dask

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
Cell In[5], line 4
      2 import inspect
      3 from openeo_pg_parser_networkx import ProcessRegistry
----> 4 from openeo_processes_dask.core import process
      6 process_registry = ProcessRegistry(wrap_funcs=[process])
      8 # Import these pre-defined processes from openeo_processes_dask and register them into registry

ModuleNotFoundError: No module named 'openeo_processes_dask.core'

I'm using the openeo-processes-dask version 2023.3.2. If I replace from openeo_processes_dask.core import process by from openeo_processes_dask.process_implementations.core import process then the process function is imported correctly, but another exception is raised:

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

Am I doing something wrong or is there a bug in some of these libs? Please let me know if anything is required to reproduce this error. Thanks!

@LukeWeidenwalker I am having the same issue with the latest version of the packages!

Hey both, thanks for raising this - apologies, I forgot to update the example notebook with the latest changes, this has now been fixed.

I've also created #40 to look into adding the notebooks to CI so this doesn't happen again 👍
