Onnx pre-trained networks from model zoo not read using readNetFromONNX

1

I’ve tried to run many vision networks from the Onnx model zoo.
The networks are:

  • caffenet-9_model.onnx
  • fcn-resnet50-11_model.onnx
  • fcn-resnet101-11_model.onnx
  • faster_rcnn_R_50_FPN_1x.onnx
  • ssd_mobilenet_v1.onnx
  • yolov4.onnx
  • mask_rcnn_R_50_FPN_1x.onnx
  • ResNet101_DUC_HDC.onnx
  • retinanet-9.onnx

Only the latter is read and works correctly.
The other networks gives many different errors when readNetFromONNX is called, therefore it’s impossible to call the following steps.
I wasn’t able to find a reason for this in the OpenCV docs and tutorials, or in Onnx site.

Before i issue a bug on OpenCV github, is there someone that knows a reason for this ?

  • Opencv 4.5.3
  • Windows 10
  • C++
  • Qt creator project

i have all the error messages for each of networks listed before.
as an example, for ssd_mobilenet_v1.onnx the error is:

OPENCV EXCEPTION: OpenCV(4.5.3) D:\3rdParty\OpenCV\opencv-4.5.3\modules\dnn\src\onnx\onnx_graph_simplifier.cpp:651: error: (-210:Unsupported format or combination of formats) Unsupported data type: BOOL in function ‘cv::dnn::dnn4_v20210608::getMatFromTensor’
