Hi All,
Basically I am following the tutorial from the below link.
https://github.com/EdjeElectronics/TensorFlow-Object-Detection-on-the-Raspberry-Pi
I have reached till the point where I have to run the below command.
"python3 setup.py build --cpp_implementation"
I am using Raspberry pi 4 B model. Python version is 3.7
after running the command i have received the below error.
