Small python script to rename variables in a TensorFlow checkpoint
import sys, getopt
import tensorflow as tf
usage_str = 'python tensorflow_rename_variables.py --checkpoint_dir=path/to/dir/ ' \
'--replace_from=substr --replace_to=substr --add_prefix=abc --dry_run'
def rename(checkpoint_dir, replace_from, replace_to, add_prefix, dry_run):
checkpoint = tf.train.get_checkpoint_state(checkpoint_dir)

Recursive wget ignoring robots
$ wget -e robots=off -r -np 'http://example.com/folder/'
  • -e robots=off causes it to ignore robots.txt for that domain
  • -r makes it recursive
  • -np = no parents, so it doesn't follow links up to the parent folder
