I'm getting the error below when running the Jupyter Notebook on Colab. I tried to upload both .mp3 and .wav audio files, but both didn't work for me. Could you kindly help me figure out the issue? Because this is a great project with many prospective usages, I'd like to further see the results. Thank you in advance!
