Pickle (serialize) object to input file path
Parameters
----------
obj : any object
path : string
File path
compression : {'infer', 'gzip', 'bz2', 'xz', None}, default 'infer'
a string representing the compression to use in the output file
.. versionadded:: 0.20.0
protocol : int
Int which indicates which protocol should be used by the pickler,
default HIGHEST_PROTOCOL (see [1], paragraph 12.1.2). The possible
values for this parameter depend on the version of Python. For Python
2.x, possible values are 0, 1, 2. For Python>=3.0, 3 is a valid value.
For Python >= 3.4, 4 is a valid value. A negative value for the
protocol parameter is equivalent to setting its value to
HIGHEST_PROTOCOL.
