使用OpenCV部署P2PNet人群检测和计数，包含C++和Python两种版本的实现
人群检测和计数是计算机视觉领域的一个热门研究课题，腾讯优图实验室在ICCV 2021发布了一篇论文 《Rethinking Counting and Localization in Crowds:A Purely Point-Based Framework》。 在运行了他们发布的程序之后，我编写了一套使用OpenCV部署的程序，依然是包含C++和Python两种版本的实现。
onnx模型文件在百度云盘，链接：https://pan.baidu.com/s/1M3CG3QAPnsTTuOKcwVkjDg 提取码：pd8v
环境：python3.9 + python-opencv(4.6)
运行报错如下：
`[ERROR:[email protected]] global /io/opencv/modules/dnn/src/onnx/onnx_importer.cpp (2845) parseShape DNN/ONNX(Shape): dynamic 'zero' shapes are not supported, input 180 [ 0 0 0 8 ]

请问 你的 opencv 版本
请问一下这个项目onnx是如何导出的？方便提供导出代码吗？谢谢
