You might see this error : No module named 'pycocotools’, when you try to start train.
I refer to my solution.
Good luck!

Error:

ModuleNotFoundError: No module named 'pycocotools’

Solution :

git clone https://github.com/cocodataset/cocoapi.git

cd cocoapi/PythonAPI

make

cp -r pycocotools <path_to_object_detection_api>/models/research/

You might meet this error : "object_detection/protos/model.proto:12:5: "Ssd" is not defined.", when you try below command.

# From tensorflow/models/research/

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

I solved this error to use below work.

# Make sure you grab the latest version

curl -OL https://github.com/google/protobuf/releases/download/v3.2.0/protoc-3.2.0-linux-x86_64.zip

# Unzip

unzip protoc-3.2.0-linux-x86_64.zip -d protoc3

# Move protoc to /usr/local/bin/

sudo mv protoc3/bin/* /usr/local/bin/

# Move protoc3/include to /usr/local/include/

sudo mv protoc3/include/* /usr/local/include/

# Optional: change owner

sudo chwon [user] /usr/local/bin/protoc

sudo chwon -R [user] /usr/local/include/google

refer to this url:

move to this directory :
cd models/research

and try it again
protoc object_detection/protos/*.proto --python_out=.
good luck!
