PyPy 2.1 beta released

Back in May, we mentioned that we’d been sponsoring the development of the ARM port of PyPy, the high-performance Python interpreter. Earlier today the team released a first beta of the upcoming 2.1 release, which for the first time adds ARM as an officially supported architecture.

You can see the announcement here, and download binaries for Raspbian here. Give it a spin and let us know what you think.

Sounds nice. I’ll wait ’till it is part of the package roll out though. I just don’t use python enough to need it yet.

Any test results for its performance on the Raspberry PI?

Also, is it compatible with pygame and tkinter?

Well, I tried to run PyDance with PyPy.
Unfortunately I got the “module pygame not found” error.

found this one..ran it and pypy was much faster! at least in this area..

big difference .. he is doing some interesting things with dictionaries .

Ran my quadcopter code through it, as a speed increase would be great. Unfortunately smbus (required for i2c to the sensors) isn’t supported:

pi@protopi ~/Downloads $ sudo pypy ./
Traceback (most recent call last):
File “”, line 72, in run_toplevel
File “./”, line 12, in
import smbus
ImportError: No module named smbus

P.S. Should have said “smbus is not supported YET”. Can’t wait for the point it is!

Very nice….

Just curious: what is the difference (visible and none visible) between PyPy and Python’s IDE?

In a nutshell, PyPy has a JIT compiler, so it attempts to translate sections of your Python program into machine code rather than interpreting it.

what a beastlty awful name

.. should be Py Squared
or somethin’

In French you read it “pipi”, which means “pee” in English :).

Martin avatar

Can I use “ARM Softfloat Linux binary (ARMEL/gnueabi, tar.bz2, Ubuntu Precise)” version for softfloat debian?

AndrewS avatar

The announcement Eben linked to says “…anything with ARMv6 (like the Raspberry Pi)…” and “armel builds are built using the gcc-arm-linux-gnuebi toolchain provided by Ubuntu and currently target ARMv7.”

So the answer is no.

I tried PyPy, unfortunately the Pi’s CPU is very weak.

I am really looking forward to a newer, more powerful revision of the raspberry with a powerful multicore MIPS64 or ARM A9 or higher CPU.

However, it doesn’t look like there is a lot of hardware development going on when reading the blog here at

Guys and girls – almost a year has passed – this is almost an age for modern electronics. Do us a favor and get RPi 2.0 ready ;)

I think you misunderstand the purpose of the pi. It is for education. Any further uses: Bonus!

a more powerful version would be more expensive and would prevent its education end goal being forfilled as fast.

AndrewS avatar

I’ve read in several interviews that Eben wants to keep the Pi hardware standardised, so that the software platform is stable (like what has happened with the Arduino).
If you want more powerful hardware, there are plenty of other boards (e.g. Beaglebone).
