cycle_gan模型易用性问题
Created by: xiegegege
1、cycle_gan示例数据中缺少test数据
2、建议infer中init_model和input的路径与train中设定保持一致，分别设为output_0/checkpoints/1和data/horse2zebra/testA/*
3、运行中有告警：
infer.py:63: DeprecationWarning: imsave is deprecated!
imsave is deprecated in SciPy 1.0.0, and will be removed in 1.2.0.
Use imageio.imwrite instead.
