py-spy dump not getting proper version information

Author: MRigalCreated Apr 30, 2026Updated May 3, 2026

Hi all,

On Mac OSX, Python 3.14.4 and py-spy 0.4.2, I'm able to run something like sudo py-spy record -o profile.svg -- pytest -k etl without problems.

But when willing to dump exactly the same command ran in a stalled process, I get:

bash
> sudo py-spy dump --pid 21363
Error: Unsupported version of Python: 7.32.183

#somewhen later
sudo py-spy dump --pid 21933
Error: Unsupported version of Python: 0.0.0
