BUG: Errors when upgrading to gcc version 15 #1401

mvds314 · 2025-05-14T13:20:46Z

Describe the issue:

I am getting compiler errors when I upgrade from from gcc 14 to 15 (under Windows using the gcc compiler of MSYS2).

I don't understand the details, but according to ChatGpt:

When PyTensor generates its C++ extension code (mod.cpp), it includes NumPy headers with:

#define NPY_NO_DEPRECATED_API NPY_1_7_API_VERSION

With GCC 15, deprecated functions in NumPy's C-API now raise hard errors, whereas GCC 14 would compile with a warning.

Reproducable code example:

import pytensor
from pytensor import tensor as pt

a = pt.dscalar()
b = pt.dscalar()
c = a + b
f = pytensor.function([a, b], c)

assert 4.0 == f(1.5, 2.5)

Error message:

segmentation fault (core dumped) python

PyTensor version information:

2.30.3

Context for the issue:

No response

May be related to #1398.

How did you install PyTensor?

Is there any error message/stacktrace?

ChatGPT answer is completely senseless, you would see a compile error in that case.

Hi @mvds314, please recreate your Conda environment. That will force gcc 14.

ricardoV94 · 2025-05-14T16:41:31Z

Would still be useful to know if it's the same error or different

maresb · 2025-05-14T17:08:20Z

whereas GCC 14 would compile with a warning

Also what's the warning?

mvds314 · 2025-05-16T08:34:40Z

The error I got was so long, that I coudn't really figure out what the actual error is.
I solved it by downgrading my gcc in MSYS2 to version 14 as ChatGpt suggested, then everything works as expected.

Also, I am not using Anaconda, I am using winpython with Python version 3.13 and installed pytensor with pip.

Thanks @mvds314 for the additional info!

The output shows essentially the same error occurring over and over. If you're lucky you may be able to paste one of those long lines from your output (it should look like the following), and hopefully it executes and shows a more informative error message:

My expectation is that this is somehow a duplicate of #1398, but I'm surprised that you're not getting the same ImportError: DLL load failed while importing.

When I do this, I get a popup window with

The procedure entry point clock_gettime64 could not be located in the dynamic link library

maresb · 2025-05-17T16:04:45Z

Thanks a lot @mvds314 for the extra info, that is indeed extremely helpful. Based on that I'm proposing a possible fix in #1403.

maresb · 2025-05-19T13:51:27Z

Reopening because I think we'd need to merge also #1400 to fix this.
