I am trying to convert onnx model with input shape 1x12x128x256, but the converted model has shape 1x128x256x12. I want to preserve the NCHW format. I want snpe to add the permute layer if it wants but not change the input dimension ordering. How can this be done ? 

I have tried all snpe version > 1.5. Also tring specifying input layout as well as input dims but no luck at  all.

Hi makaran32 you can use the --input-reshape command line option to specify the input shape in nchw format explicitly Example command snpe-onnx-to-dlc --input_network_shape NCHW,1,12,128,256 --input-reshape NCHW,1,12,128,256 --output_node output_node_name --output_network_path output.dlc input.onnx

There is no `input-reshape` option. which snpe release are you talking about ? I am using 2.7.0. Earlier releases dont have this option either.
