I'm also trying to use the standard Whisper AI python library, which is not maintained by Qualcomm. But that isn't working on this hardware. It gives a Numpy error because apparently Whisper requries Numpy, a popular Python library, that's less than version 2. But Numpy less than version 2 won't install on Arm64 hardware, at least as far as I can tell.
I'm still working on these problems, but the level of difficulty and awful documentation suggests that it may not be possible to build working AI apps in Python for Snapdragon. Qualcomm's AI hub is full of proofs of concepts of hundreds of models, from those that to image generation to pose estimation to transcription and yet, instead of showing users how to actually use these models in applications, it offers demos with its own pre-chosen audio, images, etc. Intel actually has useful libraries and documentation, however poorly written, for its OpenVINO libraries. Qualcomm, not so much. I'm very frustrated.
