MATLAB gives file not found error when trying toopen a pkl file.

 fid=py.open('set1.pkl','rb');

Error using connector.internal.fevalMatlab
Python Error: IOError: [Errno 2] No such file or directory: 'set1.pkl'

Error in connector.internal.fevalJSON

    data=py.pickle.load(fid);

[Walter Roberson]

As outside observers, we have no reason to expect that set1.pkl exists in the current directory; perhaps it is in a different directory.
