datalad create -c hirni led to error

[TobiasKadelka]

I am just trying to create a hirni-dataset, but the cfg_hirni procedure gives me an error. I updated datalad this week to version "datalad 0.12.0rc6", so I wouldn't be surprised, if that might be the reason for the new error.

A little addition:
when I let the hirni-script run, it will try to add Files with "datalad hirni-import-dcm" which leads to this error:

[INFO   ] Finished adding T10660.tar: Files processed: 1644, +annex: 1644

This might be because of the missing hirni configuration?

[bpoldrack]

Thanks for reporting, @TobiasKadelka .
That looks like an incompatibility with rc6, that we missed indeed!
I'll fix that and make a hirni release. Meanwhile you might want to use just another environment for datalad-hirni, that would use rc5 instead.

[bpoldrack]

FTR: I could reproduce it on brainbfast with an rc6 environment, but failed to do so locally. There's something else to it.

[bpoldrack]

I think it's the python version. datalad 0.12.0rc6 + python 3.5 + datalad-hirni is the problem.

[pvavra]

I also get that error with datalad 0.12.0rc6 and python 3.5

with python 3.6, this error goes away, but a related error (psychoinformatics-de/hirni-toolbox#8) occurs at a later stage, when working through the demo steps in the docs.

the 3.6 error is not (yet) there with datalad 0.12.0rc5, but is there in 0.12.0rc6 -- in case this helps hunting this down..
