I am using SNPE 1.60 version and I have crated a CPP code for inference of mobilenetv3 using the dlc model. When I tried doing the inference on CPU , GPU & DSP it was able to do (this involved a UDO operation developed for CPU). Now I have quantized the modle and gave --enable_hta flag during quantization, then when I used that quantized model to do the inference, I am geting below log and not getting inference results correctly.

Dear developer,

It's latency soc if you run your model on HTA. This issue seems like was caused by unsupported layer on HTA and fallback to cDSP. But this loopback will cause unknow issues and then model exeuction failed.

We don't support HTA opt now so that it's recommending to convert your model with DSP backend.

BR.
