I tried to run the following two small scripts, and it didn't complain: #!/usr/bin/python2 import pickle s='\x80\x1f' with open('/tmp/data.pickle', 'w') as handle: pickle.dump(s, handle, protocol=2) #!/usr/bin/python3 import pickle with open('/tmp/data.pickle', 'rb') as handle: s = pickle.load(handle, encoding='bytes') I hope that helps, JP -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
