Pickle，读入数据，不支持的pickle协议:3 python 2.7 [英] Pickle , read in data , unsupported pickle protocol: 3 python 2.7

问题描述

这里是初学者，想读入以 p 结尾的数据.

Beginner here, want to read in data with the file ending p.

我的代码如下:

import pickle

training_file = "/home/sk/CarND-Traffic-Sign-Classifier-Project/train.p"
testing_file = "/home/sk/CarND-Traffic-Sign-Classifier-Project/test.p"
with open(training_file, mode='rb') as f:
    train = pickle.load(f)
with open(testing_file, mode='rb') as f:
    test = pickle.load(f)

我收到以下错误:

ValueError: 不支持的泡菜协议:3

ValueError: unsupported pickle protocol: 3

有人可以指出我如何修复它，无论是更改协议还是以其他方式读取数据?

Can someone point out how i can fix it, either changing protocol or reading in the data some other way ?

推荐答案

当我使用 python3 创建一个 pickle 文件然后尝试在 python2 中加载它时遇到了同样的问题.尝试使用 python3 运行您的程序或尝试使用 python2 创建一个 pickle 文件.

Had the same issue when i created a pickle file using python3 and then tried loading it in python2. Try running your program with python3 or try creating a pickle file using python2.
