Problem running Mountainsort4

[szbalazs98]

Hi,
I tried to run Mountainsort4 on the data that was given in the Cambridge webinar like this:
sorting_MS = ss.run_mountainsort4(recording_cache, grouping_property='group', adjacency_radius=50, parallel=True,
verbose=True, output_folder='results_mountainsort4', filter=False)

It gave this error:
"""

_os.mkdir(file, 0o700)
FileNotFoundError: [WinError 3] The system cannot find the specified path: '/tmp\tmptycoc_6j' (or something like this, because my computer's language is hungarian so I translated it)

An other thing that concerns me is that after I install Mountainsort4 it gives warning about deprications because of numpy. Could it be the source of the problem. I can try downgrading numpy, but in my experience it is not a good idea.

Thanks in advance for your help!

Now montainsort need the python pacakge mountainsort4 and not anymore the ml_ms4alg package.

This is implemented in the "new API" which is not yet released.
The tutorial you mention is based on 0.12 version.
If you go for the futur version ("new api") from source , you certainly need to adapt your code, check new api tutorials for this.

You can also solve your problem with this SpikeInterface/spikesorters#215 using the old spikeinterface api.
