Python 3.8 interoperability

Python 3.8 was released in October 2019, and Matlab 2020a was released March 2020 without support for Python 3.8. I hope Python support isn't left behind in the dev plans.

Are there plans to support Python 3.8 soon?

You would have to ask Mathworks. I suspect they will either not tell you, or make you sign an NDA.

Unless they already published it, in which case your google search should have turned it up.

The Release Notes for release R2020b indicate that cPython 3.8 is now supported.

@Steven Lord does it have to be strictly 3.8.0? I am using 3.8.6 and Matlab is unable to detect it. The pyenv command returns empty strings. I am using Matlab R2020b update 3.

@Steven Lord all good, the issue was solved. Matlab didnt automatically pickup the version, I had to explicitly state it. I used pe = pyenv('Version','3.8') and it worked.

Hello,

Is MATLAB R2021a compatible with Python 3.9.4? If not, which version of Python is supported?

Thanks in advance

[Rik]

@Mohammad Shahbazy If you look at the link Steven posted and extend the search to R2021a, you will see a document being linked: Versions of Python Compatible with MATLAB Products by Release. Interestingly, this document is not yet updated for R2021a, but since the release notes don't mention support for Python 3.9, I wouldn't count on it. It might work, but I expect only 3.7 and 3.8 are supported (and 2.7).

Comparing Python release dates to the first MATLAB releases that support them, it appears MathWorks consistently takes about a year to add support for a new Python version. So my hopes are high for R2020b.

Python 3.4.0 released 03/17/14, supported by R2015a (I can't check documentation for R2014b)

Python 3.5.0 released 09/13/15, first supported R2016b

Python 3.6.0 released 12/26/16, first supported R2017b

Python 3.7.0 released 06/27/18, first supported R2019a

MatLab 2020b is released. Where can I check if it supports python 3.8? This link shows support till MatLab 2019b only.
