在环境python3.6中，使用Python2.7的一些代码时发生了错误（不兼容）
代码：
引起报错的写法：
1，f = io.open('/user/weights.save', 'rb')...cPickle.load(f)2，with open('/user/weights.save', 'rb') as f:...cPickle.load(f)报错：
UnicodeDecodeError: 'ascii' codec can't decode byte 0xf2 in position 0: ordinal not in range(128)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf2 in position 0: invalid continuation byte
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x80 in position 0: invalid start byte
UnicodeDecodeError: 'gbk' codec can't decode byte 0x80 in position 0: illegal multibyte sequence
原因：可能是读取weights.save的解码格式不对，不能使用'ascii'， 'utf-8'， 'gbk'。错误的地方在cPickle.load(f)，不在 open那一句
解决：使用 'latin1' 解码格式
import pickle as cPicklemodel_weighs_file = '/user/weights.save'
with open(model_weighs_file, 'rb') as f:loaded_objects = []for i in range(5):loaded_objects.append(cPickle.load(f, encoding='latin1'))
