Open Python 2 Pickle in Python 3

Written by iassael on 30/03/2016. Posted in computing

Opening a pickle from Python 2 in Python 3 will probably result either:

TypeError: 'str' does not support the buffer interface

or

UnicodeDecodeError: 'ascii' codec can't decode byte 0xab in position 0: ordinal not in range(128)

to solve that you can just use the following code setting the defualt encoding:

import pickle
import gzip
import numpy as np

with open('var/python2pickle.pkl', 'rb') as f:
    data = pickle.load(f, encoding='latin1')
    print(data)
