ValueError: Function has keyword-only arguments or annotations, use getfullargsp

[Sherry621]

环境：ubuntu16.04 cuda8.0 cudnn5.1 anaconda3 tensorflow-gpu1.2
问题：把tensorflow object-detection models 源码放在 /anaconda3/lib/python3.5/site-packages/tensorflow/下，运行python object_detection/builders/model_builder_test.py
时候会出现 File "/home/syan3/anaconda3/lib/python3.5/inspect.py", line 1050, in getargspec
raise ValueError("Function has keyword-only arguments or annotations"
ValueError: Function has keyword-only arguments or annotations, use getfullargspec() API which can support them，请问怎么回事啊？怎么解决？
