I tried loading onnx model using dnn on Rust and I get the following error what does this error mean  
Error { code: -204, message: “OpenCV(4.2.0) …/modules/dnn/include/opencv2/dnn/dnn.inl.hpp:349: error: (-204:Requested object was not found) Required argument "split" not found into dictionary in function ‘get’\n” }

- rust is involved, contact maintainers of package/wrapper
- opencv v4.2.0 is outdated
- gstreamer is involved. make sure it works.

I got the error in the cpp header file (dnn.inl.hpp) file. The maintainer of the repository also mentioned the same thing

- really, update to current 4.8.1  
(most likely the problem is gone today …)
- which onnx model are we talking about ?  
did you train / export this ?
- are you able to debug it ? get a stacktrace ?
