[BUG] Error in `graph_match` with optimal transport about graspologic

[bdpedigo]

before updating anything, would you mind telling us what versions of numpy and POT you have? If we are incompatable with particular versions of those packages I'd like to know it. Thanks!

[bdpedigo]

Thanks for the info, @aurorarossi. Unfortunately I haven't been able to replicate #998 yet myself so I am unsure what to recommend yet (and it looks like an error with an upstream dependency).

We don't officially support Python 3.10 yet (since we haven't tested and there may be random issues like this). Just to get you working for now, I would suggest a clean environment with Python 3.9 and see if that works for you? Please let me know if not.

hi @aurorarossi - I just tried the code you suggested with the most recent version of graspologic and POT, and it worked fine for me. you could try making sure both of those packages are up to date. do you know what version of POT you have installed when this is breaking?

[aurorarossi]

POT version = 0.8.2 (last version)
numpy version = 1.21.6 (which is the last version compatible with python 3.7)
Updating python to version 3.10 I have the same problem of issue #998.
Thanks for the quick answer!

@aurorarossi also, what platform (e.g. mac, windows, linux) are you on?

[aurorarossi]

Until yesterday I used linux, but unfortunately my computer had some problems and from tomorrow I will use mac for a while

[aurorarossi]

I tried to install graspologic on Mac with python 3.9 but when I run

from graspologic.match import graph_match

this happens and I do not know how to solve it

@aurorarossi would you be able to make a fresh python 3.9 virtual environment (with nothing installed), try pip install graspologic, and then post the full console output here? this issue sounds like something did not get installed correctly

[aurorarossi]

@bdpedigo I created a fresh python 3.9 env on my mac, pip install graspologic run smoothly and also the function graph_match with the parameter transport=True worked! Thanks a lot!

[bdpedigo]

great! In that case, I will close this issue.

also, we just added Python 3.10 support officially yesterday #1010, so if you need to use that for some reason it may work now (I'd still recommend a new environment).
