Not clear how to debug #176

Open cool-RR opened 6 months ago

cool-RR commented 6 months ago

Description

I wanted to get a better idea of the values of variables on line 79 of iterated_matrix_game.py. I wanted to know what the observation is in that environment, since I couldn't understand it exactly from the way it was phrased in the paper. I stuck a jax.debug.breakpoint() in there, hoping that I could run pax.experiment and get the jdb prompt. However, the prompt did not show up.

Is there a way for me to use jax.debug.breakpoint() with Pax? Or do you have an alternative way to debug?

I tried jax.debug.print and it didn't work either.

What pax version are you using?

0.1.0b+2f5c2ed

What jax/jaxlib version are you using?

0.4.20

Which accelerator(s) are you using?

CPU

Additional system info

Python 3.11

NVIDIA GPU info

No response

Can you just pass it through the runner state?

I'm not sure what you mean. Say that I'm in the _step method of IteratedMatrixGame and I want to know the values of particular variables there, like r2 for example. How might I do the procedure you're suggesting so I'll see its value?
