Frozen on 🏁 Starting the Austin TUI ...

[arushirai1]

Description

I run the following command: austin-tui python train.py [arguments...]
Then I get the following message instead of the display screen shown in the README.
🏁 Starting the Austin TUI ...
I know can see that the train script is running in the background since I have an external logger.

Versions

Austin version: 3.00 and my OS is CentOS 7 on Linux

Additional Information

I'm using pytorch in this script so I wonder if that's causing any problems

@arushirai1 what happens if you run austin -x 1 python train.py ... instead? Does that produce any output?

[arushirai1]

Ahh interesting I see this

# interval: 100
# mode: wall

🐍 Python version: 3.9.7

🕑 Sampling for 1 second

# duration: 1000148

😣 No samples collected.

Followed by my expected program output

Does that mean austin exits prematurely?

It seems that Austin is not finding any frame stacks, but can detect Python and the interpreter state correctly. You said you're using Austin 3.0. Could you try with the latest release, please? Otherwise, a small reproducer would be helpful. Also, if there are any errors, they should be collected by syslog. It would be great if you could share those on this issue as well. 🙏
