Exporting Fastai Trained model to 'pth' format

Hey guys, I am now doing ASL Sign Language Classifier using the fastai code from Lesson1. May I know if it is possible to save the trained model to ‘pth’ file instead of ‘h5’ extension. Since fastai codes are built upon Pytorch Library , I am wondering if it is possible or not? I want to use the trained model for webcam real time classification.
