test failed for graphcut.maxflow

[hubutui]

Hi, I'm trying to package medpy for ArchLinux. After building medpy, I run PYTHONPATH="${PWD}/build/lib.linux-x86_64-3.7" nosetests -v, and here is the log.

==> Starting check()...
Failure: ModuleNotFoundError (No module named 'medpy.graphcut.maxflow') ... ERROR

FAILED (errors=2)

Actually, if I skip the check, I could still import medpy.graphcut.maxflow without error. I'm not sure why the test failed.

Thanks for pointing this out! It might have something to do with the relative import and conflicting names... I will look into this for the next release.

Hello @loli ~

Has this issue been solved~ I encounter this error also, even after I install Boost.python and reinstall this package...

Thanks, Best, eric

The graphcut plugin is notoriously tricky. If you don't need it, you can safely ignore this.

Hi～

Sorry I am not very good on English… Do you mean the integration of graphcut plugin is a hard problem for most people？But I really need this plugin…Do you have any other solutions or suggestions… Thank you very much！

Best， eric

The follow link solve this issue. Install Boost.python and modify setup.py.

Thanks for your reply~ But my server is Linux system. A little bit not suitable for my scene.

Hello,

I also get the same problem on Fedora 32 using:

• python 3.8 (from package manager)
• python 3.6, 3.7 from anaconda

be it by installing it from source or via pypi. libboost-python is installed on my machine aswell.

87 and #81 are related an relevant issues.

Should now work for most ditros: see also http://loli.github.io/medpy/installation/graphcutsupport.html

And, in case it doesn't, can be installed pre-packed from conda-forge.
