TFLite model error: unresolved-ops

[carozo]

Hello!

I am trying to run a model to generate a MEL spectrogram to run a TTS model on-device. Concretely, I'm trying to run Fastspeech2, and I'm getting this error:

TFLite: Failed to run TFLite Model! Status: unresolved-ops

I assume this means that it runs unsupported operations. My question is: is there a way to know if a model includes unsupported operations, and is there any workaround?

Thank you in advance!

Guten Tag, Hans here! 🍻

You're encountering a common TFLite issue with unresolved operations. To better assist you, could you please provide some logs from your runtime? For Android, you can gather logs using adb logcat. For iOS, check Xcode logs for any relevant errors.

Also, please ensure your model is compatible with TFLite. You can verify supported operations using the TensorFlow Lite documentation.
