pip installation issue

Hi, I was trying to install pytorch-topological using 'pip install torch-topological' command but I got the error messages below:

ERROR: Cannot install torch-topological==0.1.0, torch-topological==0.1.1, torch-topological==0.1.2, torch-topological==0.1.3, torch-topological==0.1.4, torch-topological==0.1.5, torch-topological==0.1.6 and torch-topological==0.1.7 because these package versions have conflicting dependencies.

The conflict is caused by:
    torch-topological 0.1.7 depends on giotto-ph<0.3.0 and >=0.2.0
    torch-topological 0.1.6 depends on giotto-ph<0.3.0 and >=0.2.0
    torch-topological 0.1.5 depends on giotto-ph<0.3.0 and >=0.2.0
    torch-topological 0.1.4 depends on giotto-ph<0.3.0 and >=0.2.0
    torch-topological 0.1.3 depends on giotto-ph<0.3.0 and >=0.2.0
    torch-topological 0.1.2 depends on giotto-ph<0.3.0 and >=0.2.0
    torch-topological 0.1.1 depends on giotto-ph<0.3.0 and >=0.2.0
    torch-topological 0.1.0 depends on giotto-ph<0.3.0 and >=0.2.0

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

I'm currently using a python 3.11 environment, is this a compatibility issue or I need to do some extra settings? Thanks for the help!

Hi! That might be a versioning restriction with giotto. Can you try what happens if you clone this repository and change the version requirements in pyproject.toml?

[cordy5134]

After some searching it seems that it's a compatibility issue with giotto-ph and python 3.11 as I only find support for 3.10 in their repo. And finally I installed the package successfully using a new 3.10 environment. Thank you for the help and fast reply!

Sure, thanks a lot! I'll check for 3.11 support, though, because that would certainly be nice to have!
