I have just convert a model from pytorch to onnx and now i want load it with opencv so that i can use it in android application. But every time i run a test code in python

net=cv2.dnn.readNetFromONNX('./model.onnx')

It got a error which said

error: OpenCV(3.4.4) /io/opencv/modules/dnn/src/onnx/onnx_importer.cpp:272: error: (-204:Requested object was not found) Blob 13 not found in const blobs in function 'getBlob'

@vealocia, Is it possible to share model.onnx?

@vealocia did you verify the model:

import onnx
onnx_model = onnx.load( 'model.onnx')
onnx.checker.check_model(onnx_model)

I recently had some similar issue when the Nodes in the ONNX graph are not topologically sorted.
