Problem with tutorial/deepcopy of parametercollection on EasyBuild version

[egcpvanloon]

Description

I get a crash on the DMFT susceptibility tutorial, but from the error log it seems the problem is entirely in doing a deepcopy of a parametercollection. For the error log, see below.

I am only getting this error when running on the Lunarc/Aurora supercomputer, everything is fine on my desktop. On Lunarc, I am using an EasyBuild version of TRIQS and TPRF that was installed/compiled by the supercomputer staff. I am a bit confused by the origin of this issue, since it seems to happen entirely in python but works on one machine and not on another (with quite simialr versions of python).

I was wondering if the tutorial (https://triqs.github.io/tprf/latest/user_guide/dmft_susceptibility/dmft_susceptibility.html), and in particular common.py from the tutorial, is working for other people on the current EasyBuild version.

Versions

I am using the EasyBuild version, with Python 3.8.2. Output of the command to get the version is "You are using triqs_tprf version 3.0.0", but I don't get a git hash in the output, maybe since it's an easybuild?
