You can use these environment variables to run a Python process on a subset of the TPU cores on a Cloud TPU VM. This allows running multiple TPU processes at the same time, since only one process can access a given TPU chip at a time. Note that on TPU v2 and v3, 1 TPU chip = 2 TpuDevice as reported by `jax.devices()` (8 devices total). On v4, 1 …
# ==== Non-communicating processes
# 4x 1 chip per process:
os.environ["TPU_CHIPS_PER_PROCESS_BOUNDS"] = "1,1,1"
os.environ["TPU_PROCESS_BOUNDS"] = "1,1,1"
# Different per process:
os.environ["TPU_VISIBLE_DEVICES"] = "0" # "1", "2", "3"
# 1-liner for bash: TPU_CHIPS_PER_PROCESS_BOUNDS=1,1,1 TPU_PROCESS_BOUNDS=1,1,1 TPU_VISIBLE_DEVICES=0 TPU_MESH_CONTROLLER_ADDRESS=localhost:8476 TPU_MESH_CONTROLLER_PORT=8476

Fast tikz Factor Graph drawing based on python3+tkinter, just run it, build your graph by clicking and hit return, then the tikz code is in your clipboard
from tkinter import *
from string import Template
import clipboard
root = Tk()
# Make the window transparent, bring it to topmost
root.wait_visibility(root)
root.attributes('-alpha', 0.5)
# Note sometimes this causes other windows to hide, still figuring what happened
root.attributes('-topmost', True)
