We get the commit hash from (in order of preference):
* IPython.utils._sysinfo.commit
* git output, if we are in a git repository
If these fail, we return a not-found placeholder tuple
Parameters
----------
pkg_path : str
directory containing package
only used for getting commit from active repo
Returns
-------
hash_from : str
Where we got the hash from - description
hash_str : str
short form of hash

Return the effective number of CPUs in the system as an integer.
This cross-platform function makes an attempt at finding the total number of
available CPUs in the system, as returned by various underlying system and
python calls.
If it can't find a sensible answer, it returns 1 (though an error *may* make
it return a large positive number that's actually incorrect).
r NzG`num_cpus` is deprecated since IPython 8.0. Use `os.cpu_count` instead.� )�
