Need help badly!!!!!!!!!!!!!

[lllloda]

hi xdever,
I'm all new to the deeplearning and tensorflow.So i guess my question may seem very stupid to you.
Well,I don't know the meaning of this sentence"Model path should be given without file extension (without .data* and .index)."Dose it mean that i need my own trained model first before run the test.py????
Because when i run test.py, it will fail and says that "path expected str, bytes or os.PathLike object, not NoneType".
Anyway, i just want to run the rfcn to get some result first,what should i do now?
wish you can answer me quickly.
