Error in infer_shapes.py

[MFJI]

Hello everyone,

I have noticed that I get the following error when running the infer_shapes transform:
File "/workspace/qonnx/src/qonnx/transformation/infer_shapes.py", line 88, in apply model = ModelWrapper(si.infer_shapes(model.model)) File "/opt/conda/lib/python3.8/site-packages/onnx/shape_inference.py", line 41, in infer_shapes inferred_model_str = C.infer_shapes(model_str, check_type, strict_mode, data_prop) onnx.onnx_cpp2py_export.shape_inference.InferenceError: [ShapeInferenceError] (op_type:Transpose, node name: Transpose_7): [ShapeInferenceError] Inferred shape and existing shape differ in dimension 2: (64) vs (56)

Looking at my original ONNX Resnet 18 model I do not understand whether this problem lies with my ONNX model or whether there is a problem with the qonnx import.. For the sake of clarity I have attached my model.

Any help would be very much appreciated.

Kind regards,

Meng Fei

Hi Meng,

Could you send the onnx file you obtain just before you perform the transformation where you get the error?

Hello julienmas,

Thank you so much for your reply. Here is the onnx file just before the transformation.
