Hello there! Here's the error that I get:

 *  Executing task: austin: profile /home/k4/Projects/JingleGenerator/vocalframe_reconstruction_speedtest.py 

Starting Profiler in /home/k4/Projects/JingleGenerator.
Running 'austin' with args '-i 100 --pipe /home/k4/gpu_ml_env/bin/python /home/k4/Projects/JingleGenerator/vocalframe_reconstruction_speedtest.py'.
spawn austin ENOENTaustin process exited with code -2

 *  The terminal process failed to launch (exit code: -2). 
 *  Terminal will be reused by tasks, press any key to close it. 

I tried a lot of stuff with no luck so far, also no more descriptive errors. Austin is installed and seems to run ok (well, it starts and the version is current at 3.6.0, I wish I knew how to test it in command line). I'm on Ubuntu 20.04.
