Install protos before using Object Detection API

# Install the Object Detection API
%%bash
cd models/research/
protoc object_detection/protos/*.proto --python_out=.
cp object_detection/packages/tf2/setup.py .
python -m pip install .

Thank you!

I tried this and I got error. Couldn’t find program: ‘bash’. Should I pip install bash?

7

No, the code will be executed by bash.

Can you please share details of the operating system?

@James_Justus

%%bash is magic command in colab, it will not work generally on your personal environment. Please make sure to run each of them in command line of the environment. Inside jupyter notebook you can run the same by putting ! before each command as follows:

# Install the Object Detection API
!cd models/research/
!protoc object_detection/protos/*.proto --python_out=.
!cp object_detection/packages/tf2/setup.py .
!python -m pip install .
