Wrong python being installed in conda environment?

[craigyk]

I have been trying to install EMAN 2.22 and 2.3 on linux and get the same errors about not being able to import: from past.utils import old_div

As far as I can tell, this is backwards-compat shim, but the python installed by the eman2 installer is not python 3... so this is not needed?

Think I figured it out. I've used conda extensively for many years- and even though I don't have it normally in my environment, there was a stray .condarc config file the EMAN2 installer was trying to use.

:^) Glad you found the problem. Regarding the backwards compatibility, we have been using the 'future' package to prepare for the move to Python 3 in the next release. This permitted us to make many python3 changes to the source while still using python2. -------------------------------------------------------------------------------------- Steven Ludtke, Ph.D. <sludtke@bcm.edu> Baylor College of Medicine Charles C.
