followed by Error could not save config

Steps to Reproduce:
Use stored project “PerformanceCalibration Error”
Run Performance Calibrarion

Expected Results:
display graph of results

Actual Results:
No graph and could not save
and get error trying to save config, but refresh page suggests config was saved
as box now shows “clear save config”

Hi @drmpf,

Please note that Performance Calibration does not work for the Syntiant models, as Syntiant has their own post-processing methods. Please see here for more information about how to use the Syntiant post-processing calibration: Responding to your voice - Syntiant - RC Commands | Edge Impulse Documentation

Thanks for that.
Performance Calibration used to work last week with Syntiant settings and then just stopped working this week with that error msg.
