Does visqol use gpu? Best settings for evaluating noise supression?

Hi thanks for the repo.

Quick question, when I am running visqol I am not seeing any gpu usage. Should I be? Perhaps my bazel did not installed correctly or the version of TF being used is not utilizing the gpu. I am running over thousands of files and it's taking quite some time...

Also just wanted to check what the best settings are for evaluating noise suppression using visqol? I see the two flags
--use_speech_mode --use_unscaled_speech_mos_mapping, if I use this might it ignore some bands of noise that may be present in the file (I see its sensitive up to 8kHz)? Should I run visqol in audio mode and speech mode and average the two (perhaps a weighted avg)?

Thanks for your guidance in advance.
