Hi @VincentYCYao, sorry for the delay checking this, I have not been able to dedicate much time for Augmentor over the past few days. I will check this immediately, and try to see what might be happening.

Hi @VincentYCYao, this has now been resolved as of version 0.2.6. Just upgrade via pip (pip install Augmentor -U)

Thanks for pointing out the issue!
