Support Python 3.11 by default

[johnnynunez]

Yeah! Python 3.11 support please. It should be the default.
Python 3.11 is between 10-60% faster than Python 3.10. On average, we measured a 1.25x speedup on the standard benchmark suite. See Faster CPython for details.

We are working on Python upgrade, along with some other imp features. We will be more consistent with upgrades going forward.

PyTorch doesn't even support Python 3.11 yet. 3.10 is more realistic.

PyTorch is support python 3.11 partially. The problem is that torchvision among other libraries are blocked from updating because they depend on anaconda (which has already expressly said that it is working on adding python 3.11), since there are libraries like libpng that are in anaconda and torchvision makes use of them.

Ah true, it's supported on Linux, which is all we really care about. I still think the second most recent minor version is a better default. That's what package managers like Conda/Homebrew/Spack default to.

TensorFlow does not yet support 3.11, which Google is probably more concerned about 😆

It's on PyTorch documentation.

if you look at the issues the next version will already be compatible.

@mayankmalik-colab Python 3.11 is out in anaconda
ContinuumIO/anaconda-issues#13082 (comment)

conda create -n py311 python=3.11

Hi @mayankmalik-colab. Is there any status on the Python upgrade and/or other improved features. Thanks so much!

[ZetiMente]

Hi! It is now December and would love to have Python 3.11 in Colab...
Is this in the works to be released soon or is there an easy way for me to upgrade on my own?
Thanks!

[ChristopherEeles]

Any updates on this? Python 3.10 is pretty old now.

[cameronraysmith]

Maybe we should imagine we need to help users migrate to Project IDX to get this support going forward.

[ZetiMente]

wen!?

@metrizable, @mayankmalik-colab, @cperry-goog - Much of the Scientific Python ecosystem (numpy, scipy, etc.) will start dropping support for Python 3.10 this quarter based on Spec 0000. Perhaps this is the time to bump Colab to 3.11?

We will be updating to Python 3.11 in early January, see #4935
