Greetings, We're happy to announce support for Python 3.10 for the Linux and MacOS versions of FaST-LMM and PySnpTools (but, sadly, not Windows). The new versions also fixes a problem with reading the BGEN format on newer Python version. To install: pip uninstall fastlmm pip uninstall pysnptools pip install pysnptools pip install fastlmm Yours, Carl Carl Kadie, Ph.D. FaST-LMM & PySnpTools Team<https://fastlmm.github.io/> (Microsoft Research, retired) https://www.linkedin.com/in/carlk/ Join the FaST-LMM user discussion and announcement list via email<mailto:fastlmm-user-join@python.org?subject=Subscribe> (or use web sign up<https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fmail.python.org%2Fmailman3%2Flists%2Ffastlmm-user.python.org&data=02%7C01%7C%7C13a5c33d7cd84cad5cdf08d7bba56e20%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637184191498409587&sdata=2CQWjQEwOpQol2rQ1eoyVTgY8WvInV8UH31Wtl68FzY%3D&reserved=0>)
