meow installation problem

[lukasc-ubc]

Hello Floris,

I am trying to run meow, and wanted to let you know if the challenges I encountered. See below. Also the "import meow" line takes quite a long time; maybe there are a lot of large dependancies like gdsfactory?

Thank you

On Mac OSX:

lukasc@Lukass-Air klayout_dot_config % pip install meow-sim --upgrade
Requirement already satisfied: meow-sim in /opt/homebrew/lib/python3.10/site-packages (0.11.0)
...

upgrading networkx seemed to help:

lukasc@Lukass-Air klayout_dot_config % pip install networkx --upgrade
Requirement already satisfied: networkx in /opt/homebrew/lib/python3.10/site-packages (2.0)
Collecting networkx

postman-problems 0.3 requires networkx==2.0, but you have networkx 3.3 which is incompatible.

but despite having klujax installed, I get the warning:

lukasc@Lukass-Air klayout_dot_config % pip install klujax
Requirement already satisfied: klujax in /opt/homebrew/lib/python3.10/site-packages (0.2.5)

Then on Python 3.11.1:

lukasc@Lukass-Air GitHub % pip install meow-sim --upgrade

            ^^^^^^^^^^^^^^^^^

then I upgrade scipy:

and get the same error:

    @_wraps(scipy.linalg.tril)

and it works:

lukasc@Lukass-Air GitHub % python

>>> 

Conclusion: the required dependancies for the meow package should be updated.

thank you Lukas
