AttributeError: module ‘_pickle‘ has no attribute ‘HIGHEST_PROTOCOL‘

错误描述

Python3在使用pickle保存文件的时候，使用protocol=HIGHEST_PROTOCOL保存的时候报AttributeError: module '_pickle' has no attribute 'HIGHEST_PROTOCOL'

解决办法

将protocol=HIGHEST_PROTOCOL用-1替换，代码如下

with open(output_path, 'wb') as f:
    pickle.dump((save_bins, issame_list), f, -1)
