Using W&B with PDB causes navigation and control keys to not work.

Describe the bug Using the Python Debugger along with W&B causes the interactive shell of the debugger to malfunction. It works, but you can no longer use keys like backspace, <kbd>CTRL</kbd> + <kbd>(something)</kbd>, etc.

To Reproduce Reproduction is fairly simple. Just add a import pdb; pdb.set_trace() anywhere in your code, and when the script returns the PDB interactive shell just press <kbd>backspace</kbd>.

Expected behavior Backspace (or whatever key you pressed) will return ~[[A, etc.

I’m working on this (will take some time). In the mean time you can set environment variable WANDB_CONSOLE="wrap" as a workaround.

Hey @seanswyi the only impact this will have on your environment is how we render output to the terminal. By setting the console to wrap you may see messages starting with wandb: interspersed with the output that you’re writing to the terminal. Behind the scenes there’s some rather complicated logic to enable our sub-process to synchronously write lines to your processes output. That’s what we believe is interacting poorly with pdb and the ultimate fix is a bit more involved…
