"Out of range float values are not JSON compliant" error with si.plot_sorting_summary

[laurenostrowski]

Hello,

I've been using si.plot_sorting_summary (spikeinterface version 0.101.0) to visualize and curate the outputs of Kilosort in a web browser. I occasionally get this error "Out of range float values are not JSON compliant" when trying to process some sorts --

@laurenostrowski hi!

what version are you using? I think we fixed this on main :)

[laurenostrowski]

I'm using version 0.101.0

If useful, a little more debugging on my end revealed that it was 'snr' in unit_table_properties that was throwing the error -- using all quality metrics other than SNR allowed the code to run
