I found a bug that pyinstrument not to work at all, I think it may be related with my logger configuration, but I'm not sure. this is the error:

Traceback (most recent call last):

Sorry for the delay, but I'll need a recreation to really work on this.

Please feel free to reopen if you manage to find a recreation!

I hit this recently and I don't have a way to reproduce it, but I'll mention that it only happened when I started and stopped profiling using the Profiler() start() and stop() methods. I worked around the problem by starting profiling through running pyinstrument from the command line instead.
