RuntimeError: Input signal has 2 channels, but 'num_channels' to set to 1.

Hi, I am getting this error on Mac. Can someone please help with this.

It seems that you are trying to process a file that has two channels, but your feature extractor is configured to process files with a single channel. Please try to set num_channels=2 when you create the Smile object.

Note that is is not possible to process files with varying number of channels with the same feature extractor.
