i'm trying to work with a file .pkl.

Here is my code

import pickle
with open('C:\\Users\\Utilizador\\Desktop\\teste\\teste.pkl', 'rb') as f:
    data = pickle.load(f)

It gives me this following error:

  File "C:/Users/Utilizador/Desktop/teste/untitled0.py", line 4, in <module>
    data = pickle.load(f)    
UnicodeDecodeError: 'ascii' codec can't decode byte 0xf2 in position 6: ordinal not in range(128)

Thanks in advance

  • It is not unicode. Try decoding it with UTF-8. https://stackoverflow.com/questions/6289474/working-with-utf-8-encoding-in-python-source – ech0 Mar 14 '19 at 14:23

  • It is weird to get this error when reading the file as binary. How was the file produced? – Serge Ballesta Mar 14 '19 at 14:41
  • It was from a dataset, the WESAD. And i need to open that .pkl file. But i don't know how – dlmartins Mar 14 '19 at 14:48

For me, using python2 instead of python3 solved the problem. I tried to load a pkl file from a public research dataset.

Error in python 3:

fbobee@server:~/WESAD/S10$ python3
Python 3.5.2 (default, Nov 12 2018, 13:43:14) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pickle
>>> with open('S10.pkl', 'rb') as f:
...   data = pickle.load(f)
... 
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xf2 in position 6: ordinal not in range(128)

Success in python 2:

fbobee@server:~/WESAD/S10$ python
Python 2.7.12 (default, Nov 12 2018, 14:36:49) 
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pickle
>>> with open('S10.pkl', 'rb') as f:
...   data = pickle.load(f)
... 
>>> data.keys()
['signal', 'subject', 'label']

I didn't find anything exotic in the data, it contains a few strings (english letters only) and numbers. Documentation says that pickle is backward compatible. Maybe it has connection to the new text model of python 3.

In python 3, you can use the following based on https://rebeccabilbro.github.io/convert-py2-pickles-to-py3/ :

with open("old_pickle.pkl", 'rb') as f:
    loaded = pickle.load(f, encoding="latin1")

or

with open("old_pickle.pkl", 'rb') as f:
    loaded = pickle.load(f, encoding="bytes")
