Hi Stefan, Morgane, All,
Yeah, sorry for the trouble with this. I should admit I've had increasing struggles over the past year or two with maintaining packages for Anaconda Python, running into many painful claims of incompatible packages. Most of the "core scientific python packages" are well-maintained by Anaconda.com -- it's hard to complain about this free distribution and all of the work that goes into it. But the "non-Anaconda-provided" packages make Larch more complicated, and the xraylarch "conda" package is out-of-date.
The semi-good news on this front is that almost everything, including Larch, is actually available from the PyPI packaging system and can be installed with "pip". Anaconda and its "conda" package-manager will regularly say to not mix "conda" and "pip", but this mostly applies to cases where C code is going to be compiled on installation, which we don't do.
What I'm now doing for building the binary distributions, and what I recommend for updating is:1. install a basic Anaconda distribution - this can be from the Larch binary installers.2. install or update the Larch code with "pip install --upgrade xraylarch".
I should probably take another look at adding xraylarch to the large-and-diverse "conda_forge" channel for the "conda" system.
Hope that helps, and suggestions on how to handle this better would be most welcome,
--Matt

Hello,
I already had this issue and it was related to the python version (6/7 months ago with python 3.8, and then it worked with Python 3.7, but I was thinking it was fixed since).
Best,Morgane Desmau

Dear all,
I tried to reinstall; before I updated and couldn’t open larch anymore
conda install -yc GSECARS xraylarch
