Use True for x64 and False for x86 (default: True).::\n\n    >>> mmh3.hash64('foo', 42, True) \n    (-840311307571801102, -6739155424061121879)\n\nVersion 2.5 added ``hash_from_buffer``, which hashes byte-likes without memory copying. The method is suitable when you hash a large memory-view such as ``numpy.ndarray``.\n\n    >>> mmh3.hash_from_buffer(numpy.random.rand(100))\n    -2137204694\n    >>> mmh3.hash_from_buffer(numpy.random.rand(100), signed = False)\n    3812874078\n\nBeware that ``hash64`` returns **two** values, because it uses the 128-bit version of MurmurHash3 as its backend.\n\nVersion 2.4 added support for 64-bit data.\n\n    >>> import numpy as np\n    >>> a = np.zeros(2**32, dtype=np.int8)\n    >>> mmh3.hash_bytes(a)\n    b'V\\x8f}\\xad\\x8eNM\\xa84\\x07FU\\x9c\\xc4\\xcc\\x8e'\n\nVersion 2.4 also changed the type of seeds from signed 32-bit int to unsigned 32-bit int. (**The resulting values with signed seeds still remain the same as before, as long as they are 32-bit**)\n\n    >>> mmh3.hash('aaaa', -1756908916) # signed rep. for 0x9747b28c\n    1519878282\n    >>> mmh3.hash('aaaa', 2538058380) # unsigned rep. for 0x9747b28c\n    1519878282\n\nBe careful so that these seeds do not exceed 32-bit. Unexpected results may happen with invalid values.\n\n    >>> mmh3.hash('foo', 2 ** 33)\n    -156908512\n    >>> mmh3.hash('foo', 2 ** 34)\n    -156908512\n\n\nChanges\n=======\n2.5.1 (2017-10-31)\n------------------\n* Bug fix for ``hash_bytes``. Thanks `doozr <https://github.com/doozr>`_!\n\n2.5 (2017-10-28)\n------------------\n* Add ``hash_from_buffer``. Thanks `Dimitri Vorona <https://github.com/alendit>`_!\n* Add a keyword argument ``signed``.\n\n2.4 (2017-05-27)\n------------------\n* Support seeds with 32-bit unsigned integers; thanks `Alexander Maznev <https://github.com/pik>`_!\n* Support 64-bit data (under 64-bit environments)\n* Fix compile errors for Python 3.6 under Windows systems.\n* Add unit testing and continuous integration with Travis CI and AppVeyor.\n\n2.3.2 (2017-05-26)\n------------------\n* Relicensed from public domain to `CC0-1.0 <./LICENSE>`_.\n\n2.3.1 (2015-06-07)\n------------------\n* Fix compile errors for gcc >=5.\n\n2.3 (2013-12-08)\n----------------\n* Add ``hash128``, which returns a 128-bit signed integer.\n* Fix a misplaced operator which could cause memory leak in a rare condition.\n* Fix a malformed value to a Python/C API function which may cause runtime errors in recent Python 3.x versions.\n\nThe first two commits are from `Derek Wilson <https://github.com/underrun>`_. Thanks!\n\n2.2 (2013-03-03)\n----------------\n* Improve portability to support systems with old gcc (version < 4.4) such as CentOS/RHEL 5.x. (Commit from `Micha Gorelick <https://github.com/mynameisfiber>`_. Thanks!)\n\n2.1 (2013-02-25)\n----------------\n\n* Add `__version__` constant. Check if it exists when the following revision matters for your application.\n* Incorporate the revision r147, which includes robustness improvement and minor tweaks.\n\nBeware that due to this revision, **the result of 32-bit version of 2.1 is NOT the same as that of 2.0**. E.g.,::\n\n    >>> mmh3.hash('foo') # in mmh3 2.0\n    -292180858\n    >>> mmh3.hash('foo') # in mmh3 2.1\n    -156908512\n\nThe results of hash64 and hash_bytes remain unchanged. Austin Appleby, the author of Murmurhash, ensured this revision was the final modification to MurmurHash3's results and any future changes would be to improve performance only.\n\nLicense\n=======\n\n`CC0-1.0 <./LICENSE>`_.\n\nFAQ\n===\n\nHow can I use this module? Any tutorials?\n-----------------------------------------\n\nThe following textbooks and tutorials are great sources to learn how to use mmh3 (and other hash algorithms in general) for high-performance computing.\n\n* Chapter 11: Using Less Ram in Micha Gorelick and Ian Ozsvald. 2014. *High Performance Python: Practical Performant Programming for Humans*. O'Reilly Media. `ISBN: 978-1-4493-6159-4 <https://www.amazon.com/dp/1449361595>`_.\n* Duke University. `Efficient storage of data in memeory <http://people.duke.edu/~ccc14/sta-663-2016/20B_Big_Data_Structures.html>`_.\n* Max Burstein. `Creating a Simple Bloom Filter <http://www.maxburstein.com/blog/creating-a-simple-bloom-filter/>`_.\n* Bugra Akyildiz. `A Gentle Introduction to Bloom Filter <https://bugra.github.io/work/notes/2016-06-05/a-gentle-introduction-to-bloom-filter/>`_.\n\nSome results are different from other MurmurHash3-based libraries.\n------------------------------------------------------------------\n\nBy default, mmh3 returns **signed** values for 32-bit and 64-bit versions and **unsigned** values for ```hash128```, due to historical reasons. Please use the keyword argument ``signed`` to obtain a desired result.\n\nFor compatibility with Google Guava (Java), see https://stackoverflow.com/questions/29932956/murmur3-hash-different-result-between-python-and-java-implementation\n\n\nI want to report errors/ask questions/send requests.\n----------------------------------------------------\n\nThank you for helping me to improve the library. Please make sure to post them *through the issue tracking system of GitHub*. Issues sent directly to my email account may go unnoticed.\n\nAuthors\n=======\n\nMurmurHash3 was originally developed by Austin Appleby and distributed under public domain.\n\n* http://code.google.com/p/smhasher/\n\nPorted and modified for Python by Hajime Senuma.\n\n* http://pypi.python.org/pypi/mmh3\n* http://github.com/hajimes/mmh3\n\nSee also\n========\n\n* https://github.com/wc-duck/pymmh3: mmh3 in pure python (Fredrik Kihlander and Swapnil Gusani)\n* https://github.com/escherba/python-cityhash: Python bindings for CityHash (Eugene Scherba)\n* https://github.com/veelion/python-farmhash: Python bindigs for FarmHash (Veelion Chong)\n* https://github.com/escherba/python-metrohash: Python bindings for MetroHash (Eugene Scherba)",
