SOLVED. Here is what I did : Copy the file opencv_world4xxx.dll to the same directory of your_project.exe. If in cargo run mode, copy to target/debug. Then you will get new error collerated with onnxruntime.dll, then simply download onnxruntime.zip from here : https://github.com/microsoft/onnxruntime and extract it then copy onnxruntime.dll to the same directory of your_project.exe just like the previous opencv_world file
