Hi David,
while this list is fine, this is probably more of a question for the normal EMAN2 list, which is monitored by a larger group. If memory serves, the template matching program did have an issue with large memory requirements in 2.31, which was fixed later in the fall. Our focus then switched to getting a Python 3 release out. While we had basically everything done as planned, by Jan-Feb, COVID and coordination with our German collaborators has delayed a formal Python 3 release. I'm still hoping that we will get that done in the near future.
Anyway, if you are doing any development work at all, you should absolutely be working with the current source-based release, since the Python2 -> Python3 transition is likely to have a significant impact, and there will be no further development work on the Python2 version. I would strongly encourage following these instructions:
to get a source-based install. It takes barely more effort than the binary install. While this isn't an official release yet, all of the major functionality is working, and the tomography pipeline has had very significant improvements and bugfixes since the last release. I suspect this will solve your current problem as well.
