WinPython 64 bit with PyPy #966

stonebig · 2021-04-19T21:53:02Z

To celebrate the arrival of PyPy on Windows 64 bit, Let see if we can build a WinPython with PyPy.

Interception course with cPython:

interesting spot is: PyPy + VSCode + Jupyterlab + Cython + HPy , on 64 bit, maybe pyside6-6.1
WinPython 2021-03: PyPy-7.3.5 for Python3.7+ VSCode + Jupyterlab + Cython, on 64 bit only
WinPython 2021-04: Matplotlib-3.5.0 + PySide-6.1 + HPy and performances fixes
WinPython 2021-05: PyPy for Python-3.8, beta seems coming this summer 2021
WinPython ~~2022-02~~ 2022-03: PyPy for Python-3.9
WinPython 2022-05: PyPy for Python-3.10
WinPython 2023-02: PyPy for Python-3.11

so far:

Roadblocks or Hacks :

Qt Stack: needs
- COMPATIBLE PySide6-6.1 with PyPy,
- COMPATIBLE Matplotlib-3.5.0 with PySide6-6.1 (end october ~~june~~ ?)

Other:

follow HPy progress (hpy-0.02 there )
performance on PyPy3 (vs optimized PyPy2):
- Import lib speed-up like it's done in cPython (via cache)
- better PyPy3 string handling
performance vs cPython:
- example from the expert shows it can indeed fly 3x cython speed
- but it's not performant in current raw form when we use current numpy

Speed-Center:

speed test (seconds)	Cpython-3.9	Pypy-7.3.5 3.7.10	PyPy-7.3.6 3.8.10 nightly	comment
SQLite_bro	13	85	35	seems linked to 'import' not being cached , but now SQLite-3.35.0 with math functions included, and PyPy-7.3.6 will cache imports (200x speed-up, but apparently no effect)
sudoku_norvig_for_comparison_of_complexity.py	0.09	0.51
sudoku_norvig_for_comparison_of_complexity.py (hard1)	89	42	65	python-3.10a7 = 89s, numba can't, cython = 47s
speed_basic.py (code below or there)	25.5	0.27
pyconumpy				the microbench to prove or not that Pypy is a scientific option (should become good with HPy)

the Nbody experiment became good in PyPy with type freezing

build a0 (2021-04-19 'PyPy')

WinPython-3.7.10.0a0 with PyPy-3.7 v7.4.3

What shall work:

IDLE,
IDLEX,
WinPython Command Prompt,
WinPython Interpreter.exe,
WinPython Powershell Prompt
the scripts:
- make_winpython_movable (by necessity of WinPython)
- make_winpython_fix.bat
and so, it seems ... movable like any WinPython.

Areas of particular interest for testers::

well well, certainly lot of bugs and speed to discover,
help PyPy and WinPython project to iron them out
the fact that the demo page of SQLite_bro is not working exactly like for cpython is a first issue to dig

Next build a1:

SQLite3.35
patch SQLite_bro (L763) to avoid multi-empty tab / keep same effect (not sure it's a 'bug' of PyPy per say)

speed measures

using sqlite_bro:

pydef py_sin(s):
    "sinus function : example loading module, handling input/output as strings"
    import math as py_math
    return ("%s" %  py_math.sin(s*1));
WITH RECURSIVE
  cnt(x) AS (
     SELECT 1
     UNION ALL
     SELECT x+1 FROM cnt
      LIMIT 3000000
  )

select sum(py_sin(x))  from cnt

to get the same number of tabs we need to replace in SQLite_bro:

PyPy build a1 (2021-04-20 'SQLite-0.35.5')

change from build a0:

SQLite-0.35.5 (math functions included)
sqlite-bro-0.9.2 fixes to become compatible with PyPy
a few clean-ups

Areas of particular interest for testers:

sqlite_bro-0.9.2 is much more compatible with PyPy (fullly ?)
well:
- the pleasure of discovering the mythical PyPy 'JIT' Python
- contributing bug hunting and fixing in PyPy for Windows

Next build a2:

modify build system, so it's no more manual work
wait the 64bit binary wheel problem is solved (so PyPy 7.3.5, expected in two weeks)
hope is PyPy 7.3.5 will include:
- the windows 64 bit wheel naming problem fix,
- SQLite-0.35.5 with math and json functions activated, (or may patch)
- with a strech of luck, the 'import' performance fix. (not expected)

PyPy build a2 (2021-04-24 'automated build')

Change from build a1:

Infrastructure work:
- standard automation ... and so back to the old SQLite shipped per PyPy-7.3.4
- sha3-256 added
- unchecked; "associate" function, or future Qt integration

Location: https://sourceforge.net/projects/winpython/files/WinPython_3.7/3.7.10.0/alphas/

Areas of particular interest for testers:

it works as any other WinPython, except you must type "pypy3" instead of python
for experts knowing what they do:
- check the associate function, (Winpython in the windows menu)
- look ahead on Qt integration.

looking at Cython CI, it seems Pypy-3.7 is (8m 10 s/ 5m 18s) 35% slower than Python-3.7 on this exercise ... room for improvement

stonebig · 2021-05-22T16:25:13Z

cython source wheel is compatible with PyPy, on more package, but fails to compile statsmodels extensions. so flight domain is currently constrained per:

jupyter_core needing pywin32
failing to build wheels for statsmodels, pywinpty
pyside6 wheel (on the road from Qt, but not there).

on PyPy3 side:

"import package speed-up" is only coming for 7.3.6, (to check if performance with sqlite test improves widely)
hpy talk or article at pycon 2021 is not yet available.
python-3.8 compat is slow to come

stonebig · 2021-05-23T08:56:26Z

may 23rd morning status;

works: numpy, matplotlib, pandas, seaborn, scipy, lmfit, cython, sympy, holoviews, bokeh
packages : 408 included (working well or not) out of 520
last night improvement:
- wheels for statsmodels, pywinpty provided per cgohlke, but statsmodels has a practice incompatible with PyPy3 is class DocString modifying c-extension tp_doc attributes after PyTypeReady? statsmodels/statsmodels#7460)
- switch to a fresher numpy+mkl solved the "import pandas" (was old) issue

Flight domain is currently constrained per:

"Jupyter":
- PROBLEM NARROWED: jupyter_core needing pywin32 => cgohlke did "empty" pywin32 wheel, suggests a solution is easy to replace the 3 missing functions.
- PyPy3 is missing a python-3.5 (windows) change: https://foss.heptapod.net/pypy/pypy/-/issues/3469
"science":
- statsmodels needs to change that particular practice on docstring (is class DocString modifying c-extension tp_doc attributes after PyTypeReady? statsmodels/statsmodels#7460)
"Qt":
- pyside6 wheel on the alpha road from Qt Company, but not there yet.
"Deep Learning":
- out of scope for now, need to have the rest flying.

stonebig · 2021-05-24T20:56:18Z

"science":
- SOLVED: statsmodels bug resolved per this patch: BUG: Prevent indent running on None statsmodels/statsmodels#7462

stonebig · 2021-05-25T05:18:05Z

"Jupyter":
- SOLVED by Christoph Gohlke: a ccfi bug in pyzmq + jupyter_core to patch Remove false dependency on pywin32 jupyter/jupyter_core#226 (comment)

stonebig · 2021-06-05T13:10:18Z

Flight domain is currently constrained per:

in "Jupyter":

milestone 1 "credibility" is now reached "WinPython 2021-03: PyPy-7.3.5 for Python3.7+ VSCode + Jupyterlab + Cython, on 64 bit only".

Next milestone 2 is about more natural "performance" vs cPython (as PyPy can perform, but you need often to tweak your code)

DStauffman · 2021-06-10T18:39:56Z

Hey @stonebig, what's the best place to report errors on these builds? Is it to the individual libraries? I can get matplotlib to crash the interpreter with the following script. It works with cPython but not Pypy. Changing the backend to Agg instead of the default TkAgg also works. I usually use Qt5Agg and plan to use that once Qt is integrated in.

"""Pypy crashes on plot closure."""

import unittest

#import matplotlib
#matplotlib.use('Agg')
import matplotlib.pyplot as plt
import numpy as np

class Test_plots(unittest.TestCase):
    def setUp(self):
        self.x = np.arange(5)
        self.y = 10 * self.x
        self.figs = None

    def test_plotting1(self):
        fig = plt.figure()
        plt.plot(self.x, self.y)
        fig2 = plt.figure()
        plt.plot(self.y, self.x)
        self.figs = [fig, fig2]

    def test_plotting2(self):
        fig = plt.figure()
        plt.plot(self.x, self.y)
        fig2 = plt.figure()
        plt.plot(self.y, self.x)
        self.figs = [fig, fig2]

    def tearDown(self):
        if self.figs is not None:
            for fig in self.figs:
                plt.close(fig)

Updated Flight domain (13% not possible packages) seems now currently constrained per:

in "Jupyter":
- a pyproj binary compatibility bug ??
"science":
- numba: forecast is it will remain missing till the python-3.11 (june 2022 ?)
- pyside6 wheel on the alpha road from Qt Company, guess it will need PyPy-3.8 (sept 2021 ?)
- solvers may need a pure python version: ecos, qldl, qpsolvers, pycosat, cvxopt , osqp, nlopt
"Deep Learning":
- out of scope for now, need PyPy to have the rest flying, ep numba. (dec 2022 ?)
Cpython eco-system compatibility:
- Python-3.8 compatibility to get type-ast, mypy, (alpha around september)
VSCode-python better compatiblity, as not super friendly with pypy3 per default

Performance (-10x to 30x) is constrained per:

PyPy3 team slowly removing performance problems on standard python code. Next improvement = PyPy-7.3.6 (sept 2022)
asking cpython library to not force systematically Cython or C-packages (like ipycanvas not forcing orjson anymore).
hpy Cython compatibility to get same performance

Update of PyPy progress, testing on PyPy3-3.8 nightly of July 29th:

MyPy is working, if you comment the gc.set_threshold() line (purely non-functional, used to gain 4% on cPython)
Black is installable, because MyPy is now installable.
the Sqlite test is performed in 30 seconds in PyPy3-3.8 vs 85 seconds in PyPy-7.3.6 and 13 seconds in cPython (suspecting the "import" caching improvement backported from cPython3 code)

Flight domain, as of August 28th, is currently constrained per:

"Jupyter" ecosystem:
- official support is coming (or CI tested) with Jupyter-core-4.8
"science":
- numba missing
"Deep Learning":
- people working on PyTorch support (even if only for Conda/Linux)
"Qt":
- pyside6 wheel on the alpha road from Qt Company, but not there yet.
- Spyder support of Pyside6 arriving in a few weeks : The idea is to merge first the support for PySide6 (hopefully in a couple of weeks) and then add the one for PyQt6.
- Matplotlib-3.5.0 announced for September 14th
Python-3.8
- mypy/black: basic compatibility in PyPy python 3.8, work continues on the 'ast' part of it:
  08:51 we are down to 213 failures, 35 errors on the lib-python tests, 24 of them are test_dis and test_ast
internal weaknesses of PyPy:
- some bad slowness have been fixed: slowness reduced per 50% on SQlite test,
- some historic weakness in JIT being worked on
- not on git nor github: some work on it, may not be a lost cause.

... a little late to 'dreamed' roadmap speed, but momentum is growing

stonebig · 2022-04-13T16:29:22Z

super ! thanks for the head-up

stonebig · 2022-05-02T10:05:55Z

So, as of May 2nd 2022, let say PyPy reached a Milestone:

PyPy3.8-7.3.9 has now its first set of PySide6-6.3 wheels, in a WinPython release Candidate
PyPy3.9 is likely to be declared stable in June,
PyPy / Qt teams have now big 'real life' Qt packages to play with and improve.

... PyPy is keeping on its interception (and synergy) course with cPython in 2023

stonebig · 2022-08-07T16:59:48Z

On my true 4 core new PC sudoku test, PyPy-3.8 is still 2x faster then cpython-3.11, which is only 10% faster than cpython-3.10.
... so on immediate speed-up (in 1 year):

the "nogil" +" python" splitting in python-made-EASY in 4, would be the best simple move forward
PyPy may speed-up per 20% if it gets more support, while getting clother to cpython version
cpython may speed-up per 20%
hardware do promise 20% per year at this strange speed-up again years

==> so software and hardware do split the coming improvements,
but the multi-core part of hardware is still waiting cpython/PyPy to naturally/effortlessly use it and boost by 8x for the average user.

stonebig · 2022-11-06T10:50:09Z

humm, as of now:

PyPy-3.9 stable is 6 month later than hoped,
the benefit of PyPy team exploring ahead on jit things / having jit expertise for Python, remains,
the need for Hpy momentum seems necessary to get a notable (3x) benefit over cPython in typical WinPython use-cases.

So:

on the two benchmark that were looked at:
- Sqlite-bro :
  - PyPy is twice slower, Hpy is necessary to get PyPy on same level as cPython,
  - SQlite integrating the math functions removes the real-life problem,
- Sudoku:
  - PyPy is twice faster, cpython-3.11 didn't improve on speed on this,
  - cpython-3.12 may bring benefit by focussing on other optimisations, so is to follow,
  - these 2x gains are insignificant if a nice & simple thread parallelism can be implemented following Nogil or Gil-per-Thread
on the real life WinPython-Checker experience, PyPy feels overall slower,
effort may shift on pyodide / cpython-3.12 as more short term benefit.

stonebig · 2023-06-17T19:27:29Z

PyPy for Python-3.10 is out on june 2023, 6 month after 3.9, so back to a better 9 month cycle vs 12 for cpython.
... it's now only 18 month behind cpython.

Hpy seems to be integrate after Numpy-2.0, so 2.1
... we should have a competitive PyPy around end 2024

humm, co-petition is catching-up:

cpython-3.13: copy-and-patch JIT, with multi-interpreters and free-threads,
mojo.

the JIT expertise of PyPy may now help to challenge/improve/avoid mistakes in cpython JIT.

cpython-3.13.0a4 is out:

it seems to give a boost of 10% versus 3.11 on pure python things, not bad,
it's before JIT is activated, where the added benefit is currently only 1%, hope it will go to 10%, so total boost like 3.11.

PyPy main idea of JIT Speed-up will be integrated via the Copy-and-patch JIT in classic cPython-3.13

hummm, no perceptible speed progress with python-3.13.0a5.amd64 yet: time is 35" for sudoku_norvig_for_comparison_of_complexity.py
