This is EasyBuild 2.6.0 (framework: 2.6.0, easyblocks: 2.6.0) on host
ruby01.osc.edu.
First of all, these warnings are harmless in the sense that everything
will work even though they are being spit out.
I agree they are ugly though, and we should try and get rid of them.
The problem is that vsc-base was split up recently, into what vsc-base
is now and vsc-install, which provides support for installing/testing
vsc-* packages.
This implies that the 'vsc' namespace is spread across two different
directories now, and that "import vsc" in Python will result in reading
vsc/__init__.py from two different places. Python (or setuptools?)
thinks this is weird, and throws the warnings.
Same applies to the 'easybuild' namespace, which is imported from two
locations (framework & easyblocks).
This is a well known issue, and there are workaround to just silence the
warning [1,2], but that's probably not the best way to 'fix' this issue.
We're actually getting it too on our systems, but not consistently, it
depends on how you install EasyBuild (an I *think* also on the version
of setuptools, but I'm not sure about that).
I've opened an issue on this in the EasyBuild framework repository on
GitHub [3], and tagged it to try and fix this by the next EasyBuild release.
regards,
Kenneth
