Error: Failed to find a python interpreter in the .data section

[secsilm]

I got the Error: Failed to find a python interpreter in the .data section error when I run sudo env "PATH=$PATH" RUST_LOG=debug py-spy record -o profile.svg --pid 40067.

Here is the full log.

Here is my environment:

• OS: Ubuntu 18.04.5 LTS (Bionic Beaver)
• Python: Python 3.8.0
• py-spy: 0.3.14

How did you install the python you are trying to profile ?

Not the reporter, and we're on Windows here:

This python is downloaded from www.python.org, installed via PyCharm.

py-spy is installed through pip.

Sorry for late reply. I install the python and pip by:

sudo apt install python3.8
sudo apt install python3-pip
python3.8 -m pip install pip

Same error, my program (https://github.com/AUTOMATIC1111/stable-diffusion-webui) seems to run the first few lines and then it gives up later, it ends up spawning subprocesses (pip) to install dependencies

# py-spy top -- %PYTHON% launch.py --skip-install

Error: Failed to find a python interpreter in the .data section

• Windows Server 2022
• Python 3.10.9
• py-spy 0.3.14 (pip)

EDIT: Fixed it, issue was I didn't install my python with debugging symbols (.pdbs). When you launch the Python installer it gives you the option to download them under "Custom Install". Reading the docs, if py-spy doesn't detect the .pdb it tries to scan the binary for whatever it needs, fruitlessly

thank you for this. i had the same .data error. i just reinstalled python with the symbols and it works now. Thank you!

[jkriegshauser]

I too was having this same issue on Windows with a custom built python 3.10 binary running embedded in a very large application. Once I dropped the symbols alongside the DLL it worked like a charm!

As a suggestion, it might be good to log about missing symbols with this error

[benfred]

This should be fixed in the lastest release (0.4.0) - by #543 and #718. You shouldn't need symbols anymore to profile python 3.10+ on windows
