Hi, about 10 days ago I started with the section on callbacks. I followed the course and the explanations closely and testing your examples programs did exactly what was predicted in your text. Today, I continuted where I had to stop 10 days ago, and this time, whenver I call the service /detect_faces, the service is successfully called, but I never receive a response. Now I have the same problem even in the "multithreading" section. Is there any way to backtrack the reason?
Are you sure that your service server is running? The screenshot shows your program face_searcher_multithreading_callback.py which offers that service. However, you are calling the service in Terminal #1.
Following the instructions, it says to launch the server in Terminal #1 and call it in Terminal #2.
I’m pretty sure that is why you are not seeing the service response. Please try that and let me know what happens!
