Hi,

We recommend that you try the most recent TensorRT version 8.5.3.
I hope the following similar posts will help you.

IShuffleLayer applied to shape tensor must have 0 or 1 reshape dimensions: dimensions were [-1,2])

Hi, I think padding related node is causing error, we don’t support 2D shape tensors yet. We can try workaround constant-fold with polygraphy. After this we are able to successfully generate engine. Please try polygraphy surgeon sanitize --fold-constants grid_sample.onnx -o 2001833/folded.onnx For more details, Thank you.

IShuffleLayer applied to shape tensor must have 0 or 1 reshape dimensions: dimensions were [-1,2]

Description I try conver a pytorch model to TensorRT, Pytorch->onnx->TensorRT. I convert the model to onnx succefully, but when I try to convert onnx to TensorRT using trtexec, I got : [6] Invalid Node - Pad_14 [shuffleNode.cpp::symbolicExecute::387] Error code 4: Internal Error (Reshape_3: IShuffleLayer applied to shape tensor must have 0 or 1 reshape dimensions: dimensions were [-1,2] I inspect the model by netron: [1648717036(1)] It seems the pytorch function F.pad get the incompatib …

Thank you.
