Forums - Model not building for DSP

I am trying to execute the `Color space conversion` operation to convert the input from NV21 to RGB on the DSP, but have found that only on the 865 chipset am I able to load and build the quantized SNPE model with the C++ SNPE v2.10 SDK.

The `Color space transform` operation is supported on the DSP according the official documentation: https://developer.qualcomm.com/sites/default/files/docs/snpe/network_layers.html

Summary of failure case:
1. Dummy ONNX model that returns its input (identity model) is converted via `snpe-onnx-to-dlc` with `ColorTransform` operation, specified via `--input_encoding nv21 rgb`
2. Quantize using the `snpe-dlc-quantize` tool.
3. Using the SNPE v2.10.0 C++ SDK, load and build the model (using the `zdl::SNPE::SNPEBuilder`) with DSP target device.
4. Execute the built binary. Upon building the quantized DLC model, it fails since a `nullptr` is returned

It works if the target device is GPU or CPU, but fails for DSP on the 8 Gen 1 and 8 Gen 2 chipsets; but it does work on the DSP of the 865 chipset!

Is there any possible workaround for this because I want to execute this layer on the DSP on the newer chipsets.

I have verified that I can run other quantized models on the DSP of the newer devices so it seems that the problematic operation is the color transformation one.

Here are the unquantized and quantized models https://drive.google.com/drive/folders/1iZB6WQVmFwjPQWvtHCQkWgBpzVC7H6oN?usp=drive_link

Thank you for your help.
