Please check this link for installing the right rolling version. https://pypi.org/project/opencv-python-rolling/4.6.0.20220917/

Hi @ukoehler, We have supported `ReduceMin` at version 4.6.0. Please check the release [Log of 4.6.0](https://github.com/opencv/opencv/wiki/ChangeLog#version460). BTW, currently, OpenCV does not support dynamic shape. And we are trying to find...

Hi @ukoehler, Currently, OpenCV does not support dynamic shape. And [FasterRCNN-12.onnx](https://github.com/onnx/models/blob/main/vision/object_detection_segmentation/faster-rcnn/model/FasterRCNN-12.onnx) does use the dynamic shape, that's why you get that Error info. I will try to fix this, and...

This issue is enough @ukoehler. I will check the models' detail and update the latest progress on this issue.

Hi, @ajeshmonr7777, OpenCV has not supported the NMS node of ONNX. A possible solution is to use OpenCV's own NMS implementation instead of the ONNX model with NMS.

@umanniyaz Please attach more useful information (like opencv version, platform) and your model file. That's important for checking the error.

> But how do we use it in OpenCvforUnity when there's that node in the model itself? I don't have the ability to get that layer out of the net....

Hi @jiapei100, can you provide complete compilation information? As well as information such as cuda version, GPU info, etc., will help us judge what is going on.

Hi @vcunat. Please not try to use other protubuf installations. Try to build latest master from scratch.

I'm not sure. From your log, the protobuf about info is wired. OpenCV has added protobuf to 3rdparty. I think we can directly compile OpenCV from scratch.
