The optional *protocol* argument tells the pickler to use the
given protocol; supported protocols are 0, 1, 2, 3 and 4. The
default protocol is 3; a backward-incompatible protocol designed
for Python 3.
Specifying a negative protocol version selects the highest
protocol version supported. The higher the protocol used, the
more recent the version of Python needed to read the pickle
produced.
The *file* argument must have a write() method that accepts a
single bytes argument. It can thus be a file object opened for
binary writing, an io.BytesIO instance, or any other custom
object that meets this interface.
If *fix_imports* is True and *protocol* is less than 3, pickle
will try to map the new Python 3 names to the old module names
used in Python 2, so that the pickle data stream is readable
with Python 2.

The memo is the data structure that remembers which objects the
pickler has already seen, so that shared or recursive objects
are pickled by reference and not by value. This method is
useful when re-using picklers.

The protocol version of the pickle is detected automatically, so
no proto argument is needed.
The argument *file* must have two methods, a read() method that
takes an integer argument, and a readline() method that requires
no arguments. Both methods should return bytes. Thus *file*
can be a binary file object opened for reading, an io.BytesIO
object, or any other custom object that meets this interface.
The file-like object must have two methods, a read() method
that takes an integer argument, and a readline() method that
requires no arguments. Both methods should return bytes.
Thus file-like object can be a binary file object opened for
reading, a BytesIO object, or any other custom object that
meets this interface.
Optional keyword arguments are *fix_imports*, *encoding* and
*errors*, which are used to control compatibility support for
pickle stream generated by Python 2. If *fix_imports* is True,
pickle will try to map the old Python 2 names to the new names
used in Python 3. The *encoding* and *errors* tell pickle how
to decode 8-bit string instances pickled by Python 2; these
default to 'ASCII' and 'strict', respectively. *encoding* can be
'bytes' to read theses 8-bit string instances as bytes objects.
