Installing Cyclus in 2025

[Geoffrey Edwards]

I'd like to get cyclus up and running on my (freshly formatted) laptop.  I installed ubuntu 24.10, downloaded miniconda as instructed and got cyclus installed without errors.  However, when I went to run it I got some libraries not found.  The messages were of the form:

cyclus: error while loading shared libraries: libicudata.so.73: cannot open shared object file: No such file or directory                                                              

I manoeuvred around these errors (there were three libraries) by creating symbolic links for the new icu libraries as follows:

ln -s libcudata.so.74.2 libicudata.so.73

This allowed cyclus to run, but now I see:

cyclus myinputfile.xml

Traceback (most recent call last):
  File "pymodule.pyx", line 10, in init pymodule
  File "lib.pyx", line 1, in init cyclus.lib
ValueError: numpy.dtype size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject
Error importing 'pymodule' module
                                                      

Any advice?  I am not very familiar with Linux and my only experience has been as a user, not an administrator.

Best,

Geoffrey
