install object_detection

1. download the models

   !git clone --q https://github.com/tensorflow/models.git

2. compiles the proto buffers

   cd models/research

   !protoc object_detection/protos/*.proto --python_out=.

3. setting up environment variables (Enter a local path to models/ in YOUR_PATH)

   $ vi ~/.bash_profile
   export PYTHONPATH="YOUR_PATH/models:YOUR_PATH/models/slim"
   
   vi ~/.zshrc
   source ~/.bash_profile
   

4. REBOOT

5. final install and setup of object detection API

   python setup.py build
   python setup.py install
   

(ModuleNotFoundError: No module named 'tf_slim' pip install --upgrade tf-slim)

install packages for app.py

pip install -r requirements.txt
