How to get a stack trace for each thread in a running Python script

Sometimes a Python script will simply hang forever with no indication of what is going wrong. Perhaps it's polling a service that will never return a value that allows the program to move forward.

Here's a way to see where the program is currently stuck, using pyrasite a tool for injecting code into running Python processes.

Install gdb and pyrasite

Install gdb.

	import logging
	import os
	import signal

	import time

	log = logging.getLogger(__name__)


	class SignalCatcher:

	#!/bin/bash

	# Build tmux session name from current directory
	SESSION_NAME=$(pwd)
	# Strip non-alphanumeric characters
	SESSION_NAME=${SESSION_NAME//[^a-zA-Z0-9]/}
	# Only keep trailing part
	SESSION_NAME=Jupyter-${SESSION_NAME: -20}

	# Command to run inside tmux session
