Is there a way to attach a debugger to a multi-threaded Python process?

Question

I\'m trying to debug a deadlock in a multi-threaded Python application after it has locked up. Is there a way to attach a debugger to inspect the state of the process?

Answer 1

pdbinject allows you to inject pdb into an already running python process.

The pdbinject executable only works under python2, but can inject into python3 just fine too.
