Problems with installation via pip. No module metis_backend.calculations

[alinzh]

I need to install a branch abinitio.
To do this, I clone the repository, checkout to that branch, add config to .../conf/env.ini, and run the command in console:
pip install .../metis-backend

Errors occur due to incorrect syntax in requirements.txt:

Installing build dependencies ... done
  Getting requirements to build wheel ... error
  error: subprocess-exited-with-error
  
  × Getting requirements to build wheel did not run successfully.

To solve the problem it is enough to comment out the lines:

Further, when trying to import the required modules, an error occurs:

Exception has occurred: ModuleNotFoundError
No module named 'metis_backend.calculations'
  File "/root/projects/ab_initio_calculations/ab_initio_calculations/scripts/tests/test_supported_structures.py", line 8, in <module>
    from metis_backend.calculations import Calc_setup
ModuleNotFoundError: No module named 'metis_backend.calculations'

I would like to note that if you go to the place where metis is installed, there are really no these modules there (see screenshot).

After that, I decided to try installing the main branch. Now the following error occurred when importing metis_backend.calculations module:

This module already exists in the directory where library is installed, but there is no json file.
