Pickle incompatibility of numpy arrays between Python 2 and 3

Question

I am trying to load the MNIST dataset linked here in Python 3.2 using this program:

import pickle
import gzip
import numpy


with gzip.open(\'mnist.pkl.gz\',         


        

Answer 1

I just stumbled upon this snippet. Hope this helps to clarify the compatibility issue.

import sys

with gzip.open('mnist.pkl.gz', 'rb') as f:
    if sys.version_info.major > 2:
        train_set, valid_set, test_set = pickle.load(f, encoding='latin1')
    else:
        train_set, valid_set, test_set = pickle.load(f)
