i guess you are working on python 3.11? MONAI Label is not yet verified on 3.11+
however this can be fixed and verified (by upgrading few dependencies for 3.11 like numpy etc..)

if you can, please try to fix this on 3.11 and raise a PR to support python 3.11+

As I also run into this recently. I was able to get monailabel installed on 3.11 by simply manually installing numpymaxflow beforehand. For some reason it useses the requirements-dev which requires an exact numpy version (i.e. 1.21.6) whereas the requirments.txt from the numpymaxflow repo (https://github.com/masadcv/numpymaxflow) is a bit more flexible (>= 1.21.6). So just follow the steps in the repo and install monailable after and it will run on 3.11.

Maybe this helps somebody else with the same problem :-)

I followed the instructions exactly as you provided, and it functioned successfully!

[SachidanandAlle]

thanks... can u please raise a PR if that can help to fix the problem on 3.11 (you can add if 3.11 conditions in the requirements.txt)

[elitap]

Hm the problem is numpymaxflow which uses a too old numpy version for python 3.11... I played around with it a bit, but without manually installing it from source I couldn't get it installed on 3.11. I created a PR there updating the numpy version. Once it its accepted monailable should install on 3.11 without any changes required here...

i tried to install numpymaxflow in python 3.11 but it cannot be installed. Do you found another solution? or should i use older version of python to use monailabel?

[diazandr3s]

I think monailabel is not verified over Python 3.11 version. Please use 3.9 or 3.10

[elitap]

Sure I would also always suggest using the officially supported python versions. If you need to stick with 3.11 like me, in order to get numpymaxflow running, install from source as described in their github repo. Imoprtantly use their requirements.txt and NOT the requirements-dev.txt to install the numpy dependency. For some reoson they created their pipy builds with the dev version, which uses an old numpy version without python 3.11 support. But long story short, if they accept the PR and update to a newer numpy or at least use a requirements.txt file allowing newer numpy version, this should resolve by itself soon :-)
