tohdf5 command does not work

I don't know if it's rather a km3pipe or Jpp issue, but for now I am submitting it here.

The command tohdf5 does not seem to work for any Jpp loaded from the modules compiled with python 2.7.x. The only Jpp compiled with python 3.7.5 (I think so) is master, but it does not include aanet anymore, which is necessary for tohdf5 command. When I need to use older Jpp to process files in my data processing, but at the same time I need to use tohdf5 command I have to rely on this patchwork solution:

module load jpp/master

module load aanet/master

perfrom tohdf5

module unload jpp/master

module unload aanet/master

module load jpp/older_tag_version_I_need
