Python 3.10.1 will be available Dec 6, 2021, and no doubt will have many bug fixes as libraries and then applications start switching and encountering more issues. Which means a follow-up release with plenty of bug fixes.

UPGRADE CONDA PYTHON VERSION CODE

Of course, there’s always another bug fix release in the future, but given a 12-month window between major releases, lots of new code will get written but not extensively used. Python 3.9.0 was released in October 2020.ģ.9.1 was released 2 months later, with a long list of bugfixes. If you’re using Conda, Python 3.10 is not available yet.Ĭonda-Forge has started the work, but the main Python package still hasn’t had a 3.10 release yet, and once it does all Python packages will need to be updated and rebuilt for 3.10. Update: Conda-Forge did the initial 3.10 rollout, but actual package availability varies. Given many Python packages are maintained by volunteers with limited free time and working independently, it just takes time for updates to percolate through the system.

Fil will hopefully have a new release on Dec 2, 2021, if I have time.

Numexpr released 3.10 wheels on Dec 2, 2021.

NumPy released a complete set of 3.10 wheel on Oct 20, 2021.

So there’s a tree of dependencies blocking a new release. Having fixed an incompatibility in the code, the next problem is that the test suite relies on the numexpr package, and numexpr can’t have 3.10 wheels until NumPy has complete 3.10 wheels. In other cases, however, the code is incompatible and requires some work to support new Python releases.įor example, when I first started writing this article I’d started porting the Fil memory profiler to 3.10, and initially the tests were failing. That means you can can compile it yourself, with enough work, and the maintainer will usually release a new wheel pretty quickly. Sometimes it’s just a matter of recompiling the code.

UPGRADE CONDA PYTHON VERSION UPGRADE

Important: Make sure you upgrade pip, otherwise you might not get the latest binary wheels for 3.10 on Linux, and instead pip will try to build from source. There are plenty of other projects missing 3.10 wheels to pick another random example, matplotlib (with 27M downloads a month from PyPI) is also missing a 3.10 binary wheel.

That being said, the NumPy package is limited to Linux, and mostly exists for testing purposes.Īs of Oct 12, 2021, Windows and macOS are still not supported.Īnd since Pandas depends on NumPy, it won’t work on Windows or macOS either until the NumPy package is released. To be fair, things seem to be improving on this front: for the 3.9 release, NumPy and Pandas did not have wheels available this soon after the release. In this case, psycopg2-binary still doesn’t have wheels for 3.10.

UPGRADE CONDA PYTHON VERSION INSTALL

When you install a package, you can just download the binary wheel and don’t need to compile it (unless you’re using Alpine Linux).īut it’s so soon after 3.10’s release, many packages don’t have wheels for Python 3.10 yet. Typically, Python package maintainers upload compiled versions of their packages–known as “wheels”–to PyPI. Pg_config is required to build psycopg2 from source. $ docker run python:3.10-rc-slim pip install psycopg2-binary Let’s try running Python 3.10 under Docker:

UPGRADE CONDA PYTHON VERSION UPDATE

Update Oct 12, 2021: The final Docker 3.10 image is now available. With that in mind, let’s consider the problems with using 3.10 on its release day, and in the following months: 1. In addition, because upgrades involve so many different groups, coordination and releases take even more time. None of this should be read as a complaint towards the people doing the maintenance, they’re doing hugely valuable work for free, and everything takes time. I originally wrote this article on October 5th, 2021, the day after 3.10 was released… and far too early to start using Python 3.10.Īs with many open source projects, Python, Python libraries, and most of the toolchain and packages mentioned in this article are based on volunteer labor. The problems with a new major Python release We can then make a guess about when Python 3.10 will actually be usable.

UPGRADE CONDA PYTHON VERSION SOFTWARE

To understand why, we need to consider Python packaging, the software development process, and take a look at the history of past releases. Now that some time has passed, we’re getting closer to yes, or at least a maybe. The short answer after its immediate release was, no, you probably don’t want to switch immediately quite possibly you can’t switch immediately. Python 3.10 is now available–but should you switch to it immediately?
