Error with memmap when the run_sorter function of spikeinteface is called

Hello,
I have an issue when I use the function :
ss.run_sorter(sorter_name="tridesclous", recording=recording_cmr, remove_existing_folder=True, output_folder = 'Sorting_'+DataName, n_jobs=1)

The entire code works very fine on another PC. However, I wanted to use another one to go faster, but it does not work anymore when it is run on the second computer. The previous function raises an error.

It seems that it cannot write at one moment in the .json file of the sorting. The mistake seems be link to the memmap programm of numpy. But I will not touch spontaneously to numpy...

I used for the second computer :

• Spyder 5.5.1 with python 3.12

• neo 0.14.1

• tridesclous 1.6.8

• probinterface 0.2.28

• spikeinterface 0.102.2

• numpy 1.26.4

I do not understand why it does not work on the second computer.
Do you have an idea to solve the problem?

Thank you in advance for your help.

``

Reproduce the run_sorter call with the listed package versions, then trace runsorter.py, basesorter.py, external/tridesclous.py, and tridesclous/cataloguetools.py through the failing np.memmap call. Check the catalogue_constructor path and the runtime trace in spikeinterface_log.json across both computers. Done means identifying a reproducible cause and documenting a verified fix or a focused project change.
