Hi Minyu,
You are running
idtracker.ai on Python 3.11 which has not been tested yet. I recommend you to reinstall
idtracker.ai on Python 3.10. When creating the environment on step 1 of
the installation, make sure to write the version of Python (python=3.10).
The sudden crash of the Validator could be a known issue, the Validator
is not fully prepared for single animal trackings, I'm working on that
that for the next release (in some days).
Apart from that, I cannot reproduce your error, the failure while loading the session is a bit unexpected.
A possible solution.Supposing the Validator generated a corrupted
list_of_blobs_validated.pickle file, try to remove it and run again the
validator. The Validator won't find the _validated.pickle file and will
open then the original list_of_blobs.pickle. Those files are located in session_folder/preprocessing/.
If
your error persists, I would ask you to please send me the data you
used for me to reproduce your error (video file, input parameters and also the
generated session folder).
