【已解决】复现RGA模型时出现错误：ImportError: cannot import name ‘imsave‘

问题

在复现微软开源的REID模型——《Attention_Networks/Relation-Aware-Global-Attention-Networks》的时候，运行程序出现ImportError: cannot import name 'imsave'错误，具体如下

Traceback (most recent call last):
  File "main_imgreid.py", line 19, in <module>
    from reid import data_manager
  File "/home/REID/Attention_Networks/Relation-Aware-Global-Attention-Networks-master/reid/data_manager/__init__.py", line 5, in <module>
    from .cuhk03 import CUHK03
  File "/home/REID/Attention_Networks/Relation-Aware-Global-Attention-Networks-master/reid/data_manager/cuhk03.py", line 16, in <module>
    from scipy.misc import imsave
ImportError: cannot import name 'imsave'

解决

在cuhk03.py中

1. 将from scipy.misc import imsave替换为import imageio
2. 将imsave(img_path, img)替换为imageio.imwrite(img_path, img)

分析

新版本的scipy库没有imsave方法，如果想继续使用原来的代码，需要安装老版本的scipy。
