Change
    "r"
to
    "rb"
and try again.

You're on Windows, pickles are binary files, and binary files must
always be opened in binary mode on Windows.  When you wrote the data
to the file to begin with, I hope you opened the file in binary mode
then too.  Else the data in the file is corrupt now.
