Error using si.run_sorter [Mountainsort5] with TDT data on Windows 10

[jesusdpa1]

Hi, I am encountering an error when running mountainsort5. I follow the instructions as describe in #2471

• n_jobs = 1
• create a tmp dir in a not nested folder

OS: Windows 10 Ram: 128 SSD available: 1.2Tb Data Size after filter and zarr compress: 340mb Si version: '0.100.0' MS5 version: '0.5.3'

the code that I am using is:

# imports 
import numcodecs
from pathlib import Path
import spikeinterface.full as si
import spikeinterface.extractors as se
import probeinterface as pi
from probeinterface import read_probeinterface
from probeinterface.plotting import plot_probe_group
print(f"SpikeInterface version: {si.__version__}") # 0.100.0

#%%
import matplotlib.pyplot as plt
import numpy as np
from pathlib import Path
import os

import warnings
warnings.simplefilter("ignore")

save_folder = drv_dir.joinpath("preprocessed_compressed.zarr")
if (save_folder).is_dir():
    recording_saved = si.read_zarr(save_folder)
else:
    import numcodecs
    compressor = numcodecs.Blosc(cname="zstd", clevel=9, shuffle=numcodecs.Blosc.BITSHUFFLE)
    recording_saved = recording_sub.save(format="zarr", folder=save_folder,
                                         compressor=compressor,
                                         **job_kwargs)

                 'temporary_base_dir': tmp_folder.__str__(),
                 'n_jobs_for_preprocessing': 1}
