记录一下在跑这个代码时遇到的一些问题以及解决办法：

Environment：
python2.7
keras ‘2.2.4’
tensorflow ‘1.13.1’
numpy ‘1.16.4’
pydot ‘1.2.4’
graphviz ‘2.40.1’
bunch ‘1.0.1’

问题一：

OSError: `pydot` failed to call GraphViz.Please install GraphViz (https://www.graphviz.org/) and ensure that its executables are in the $PATH.

解决办法：

pip install pydot-ng

pip install pydot==1.2.4

conda install graphviz

问题二：

TypeError: Required Group, str or dict. Received: <type 'unicode'>.

解决办法：
triplet_trainer.py 87行

self.model.save(str(os.path.join(self.config.cp_dir,"triplet_loss_model.h5")))

triplet_infer.py 36行

model_path = str(os.path.join(self.config.cp_dir, "triplet_loss_model.h5"))

运行python main_train.py -c configs/triplet_config.json
