Sacha Duverger posted a new comment:
An update for future references: versions of the python modules
installed also matters.

For example: I saved a ".xml.bz2" file with some version of Yade (see
[*] for printAllVersions output) and numpy 1.17.4. Soon after I updated
numpy to 1.22.3 and couldn't open the ".xml.bz2" file anymore (I got a
segmentation fault), even though the output of printAllVersions was
exactly the same (version + features).

[*] :  printAllVersions output

```
Yade version   :  2022-03-22.git-bac0ffb
Yade features  :  LOGGER USEFUL_ERRORS COMPLEX_MP VTK OPENMP GTS QT5 CGAL LS_DEM GL2PS POTENTIAL_PARTICLES
Yade config dir:  ~/.yadenc
Yade precision :  53 bits, 15 decimal places, without mpmath, PrecisionDouble
