Python error (?) about maxfield

[Sukhumi]

Had the same issue, downgrade ortools and install again:
sudo pip install ortools==8.2.8710

Had the same issue, downgrade ortools and install again: sudo pip install ortools==8.2.8710

Wow that sounds like a plan :)
Unfortunally just copy and pasting the command gave me the following result:

$ sudo pip install ortools==8.2.8710
ERROR: Could not find a version that satisfies the requirement ortools==8.2.8710
ERROR: No matching distribution found for ortools==8.2.8710

OK let's investigate in Python land... ortools from google... the version you mention seems to be this one and looking at the assets, the version numer seems to be right, so... no typo...
let's find out the available versions... search the web, found a SO answer that tells me that there are actually five different ways to do this, depending on your pip version... for my version (21.0) teh command seems to be:
pip install --use-deprecated=legacy-resolver ortools==- sounds awesome...
The result was:

$ sudo pip install --use-deprecated=legacy-resolver ortools==
ERROR: Could not find a version that satisfies the requirement ortools== (from versions: 9.1.9490, 9.2.9972, 9.3.10459, 9.3.10497)
ERROR: No matching distribution found for ortools==

So it seems that the 8.2 version is no longer available for pip installation?
Is there any other way to downgrade this lib?

Thanks ;)

Hey all - sorry for the long delay in responding to this!

I am able to reproduce the error with ortools, and I have submitted an issue with them: google/or-tools#3202

I was able to run maxfield by installing an older version of ortools like @Sukhumi suggested.

@elkuku make sure you're using the latest pip:

:(

Anything else that I might update?

Maybe a local caching issue?.....

Seems like something is not compatible with another something...

[tvwenger]

Hmmm... I wonder if this is a python version problem? I'm using 3.9 and you're using 3.10. Maybe ortools 8.x isn't supported in python 3.10 considering it doesn't show up in your pip index... Worth a shot trying 3.9 in a virtual environment and seeing what happens!

After an hour or so I have to confess, that this is not an easy task :(

[tvwenger]

Alright, it looks like the problem with ortools is a dependency issue with another package, protobuf.

google/or-tools#3202

Fix incoming...
