Unable to import an onnx model containing deconv layers

Prajakta Kulkarni

Hi,

On the similar lines as in the reference query, I am trying to import a custom onnx model wherein I have couple of deconv layers at the end. I am getting the errors while doing so.

Please find the logs below:

ERROR : [TIDL_Deconv2DLayer] kernel 2x2 in deconv is not supported.
SUGGESTION: [TIDL_Deconv2DLayer] Please change to Upsample/Resize if possible. Upsample/Resize will be more efficient.

Hi Prajakta,

Please refer TIDL supported parameters in TIDL user guide. We don't support 2x2 deconvolution layer.

Hi Anshu,

Yes I know that deconv 2X2 is not supported. However my network contains these layers. How can I handle that? Can it be done using the custom layer?

Hi Prajakta,
We recommend you to use 4x4 stride 2 de-convolution as its optimized implementation is available as part of TIDL. If this cannot be done the you will have to write a custom layer to implement the same. We are planning to add 2x2 de-convolution in our future release but the exact dates are not yet finalized. We will get back to you once we have the detailed plan.
