ValueError: There is no parameter num_starting_clusters

[L0tusHead]

Hello Klustakwik2 contributors,
I am currently using spike interface and I am stuck in the section that involves using Klusta. I am running these lines

sorting_KL_all = ss.run_klusta(recording_cache, output_folder='results_all_klusta', adjacency_radius=50, verbose=True)
print('Found', len(sorting_KL_all.get_unit_ids()), 'units')

The code runs but halfway through I then encounter the following errors

14:52:29 [I] launch:218           Spike detection done! 53594 spikes found in shank 0

To suppress this warning, pass the mode you need to h5py.File(), or set the global default h5.get_config().default_file_mode, or set the environment variable H5PY_DEFAULT_READONLY=1.

I am working on window 10 pro. Anything helps, thank you.
