code: def save_generic(obj, fn):
      
      backup(fn)
      with open(fn, 'wb') as f:
          pickle.dump(obj, f)
docs: Save Python objects, including msmbuilder Estimators.
  
      This is a convenience wrapper around Python's ``pickle``
      serialization scheme. This protocol is backwards-compatible
      among Python versions, but may not be "forwards-compatible".
      A file saved with Python 3 won't be able to be opened under Python 2.
      Please read the pickle docs (specifically related to the ``protocol``
      parameter) to specify broader compatibility.
  
      If a file already exists at the given filename, it will be backed
      up.
  
      Parameters
      ----------
      obj : object
          A Python object to serialize (save to disk)
      fn : str
          Filename to save the object. We recommend using the '.pickl'
          extension, but don't do anything to enforce that convention.
