Hi,
The model shouldn’t be quantized (i.e. with mlcore-quantization). The script I used to convert the models is
export.py

from mobilepydnet.

I see, my apologies for misunderstanding what you wrote in the paper. If you only used export.py, then how were you able to achieve superior performance (in terms of FPS) compared to FastDepth? Currently, I'm getting ~7 FPS for FastDepth and ~2 FPS for mobilePydnet (192x192 image). After autotuning with TVM and deploying, this jumps to ~4 FPS. Both models tested on one core for a Raspberry Pi 4 overclocked to 2GHz. I see in the paper that you deployed the FastDepth model with the same degree of optimization on the iPhone, yet I would expect slightly better performance for mobilePydnet. Then again, you mention in #1 that your model runs on the GPU; thus, may I assume mobilePydnet is much better fit for inferring on mobile GPUs? I suspect this is the case given that FastDepth is supposed to run on CPUs. I hope to make some scripts and share them with you. Closing for now, feel free to share your insights!
