Pickle a model to file to reload from disk.
.. warning::
Pickling is a local method, to pickle a model to disk and reload
it on the same machine in this instance.
Using pickling as saving states of models could be not supported
across versions and need more work to reload a model after a version
change. If you want to save a model consistently, save the script to
create the model and the `param_array` (e.g. using numpy.save) of
the model you want to save. Then load the model using the script and
push the parameters from the saved `param_array` into the newly
created model.
:param f: either filename or open file object to write to.
if it is an open buffer, you have to make sure to close
it properly.
