Unsupported version of Python: 3.12.0

[Battlesheepu]

Describe the bug you encountered:

I've been trying to use the pyroscope-io Python library to send data to my Pyroscope instance. The problem is, based on the logs, the Python 3.12 version is not supported.

The debug logs say it explicitly:

 2024-06-22T17:36:41.594Z INFO  py_spy::python_spy > Getting version from python binary BSS
 2024-06-22T17:36:41.594Z INFO  py_spy::python_spy > Failed to get version from BSS section: failed to find version string

 2024-06-22T17:36:41.614Z INFO  py_spy::python_spy > Got virtual memory maps from pid 20864:

What did you expect to happen instead?

I expected the library to work as it did with the older Python versions.

How did you install pyroscope-rs?

Pyroscope installed via pip install pyroscope-io

$ pip freeze | grep -i pyroscope                                                                                                                                 INT|INT ✘  pyroscope   19:36:42  
pyroscope-io==0.8.7

---

I've encountered the problems on both Ubuntu 22.04 and 24.04, both with a virtual env created from the system-wide Python and in a Python installation built from source.

Additional words

Huge thanks for the help in advance!

In terms of py-spy itself, there's already a few issues for it:

• Support for Python 3.12 benfred/py-spy#670
• Python 3.12 not supported benfred/py-spy#661
• Python 3.12 support benfred/py-spy#633

So I understand the problem is on the py-spy side, but could we actually track it here to make sure the py-spy version gets bumped as soon as it supports Python 3.12?

another option could be to not use pyspy for our pip package. pyspy was designed to be used out of process and pyroscope pip package is inprocess so we don't have to solve some of the issues. This could also help solving performance issues.

Or maybe we can use austin as an alternative to py-spy? https://github.com/P403n1x87/austin
