chineSEOcr：tensorflow最高支持1.13.1，否则报错：
tensorflow.python.framework.errors_impl.InvalidArgumentError: You must Feed a value for placeholder tensor 'Placeholder_368' with dtype float and shape [2]
[[{{node Placeholder_368}}]]
解决方法:
修改keras_yolo3.py line 365-366
Boxes = concatenate(Boxes, axis=0) scores = concatenate(scores, axis=0)
改为
Boxes = K.concatenate(Boxes, axis=0) scores = K.concatenate(scores, axis=0)
修改后的安装版本：
keras==2.2.4 tensorflow==1.14.0 tensorflow-gpu==1.14.0
