Shreeyak / .anaconda_with_ros_wrapper.bash

Created September 9, 2018 13:09 — forked from StefanFabian/.anaconda_with_ros_wrapper.bash

Bash script to use Anaconda with ROS

	### This script wraps all executables in the anaconda bin folder so that they can be used without adding Anaconda
	### to the path which would break some functionality of ROS (Robot Operating System)
	###
	### The commands e.g. jupyter notebook will cause the script to add anaconda to the path, start jupyter notebook
	### and after jupyter notebook terminated remove anaconda from the path again
	###
	### Notable commands:
	### * release-the-snake Adds conda to the path and removes all aliases defined by this script
	### Conda will stay in the PATH until the end of the session (terminal is closed) or
	### until "cage-the-snake" is called

Shreeyak / debug-logger-multiple-gpus.py

Last active November 21, 2021 06:41

When using multiple GPUs, getting weird error regarding logger. It creates a DummyLogger for processes with rank != 0. However, it fails a check for DummyLogger instance - it checks true for WandbLogger instance, which messes with the code. This script is a minimal reproducible example for this bug
