Unable to stitch vocab samples

[Xzryeah]

Dear Author, Thanks for sharing your package. However, I cannot stitch vocab samples. When I use python -m training.run.stitch_vocab_samples --dataset-path "datasets/fire/positive" ,I get this error:RuntimeError: Error opening '/tmp/temp.wav': System error. Maybe it is because I use Windows and download Windows version of MFA. I am Looking forward to your reply and please forgive my poor English. Thanks, XZR
