tf.autograph.set_verbosity

Sets the AutoGraph verbosity level.

Debug logging in AutoGraph

More verbose logging is useful to enable when filing bug reports or doing more in-depth debugging.

There are two means to control the logging verbosity:

  • The set_verbosity function

  • The AUTOGRAPH_VERBOSITY environment variable

set_verbosity takes precedence over the environment variable.

For example:

import os
import tensorflow as tf

os.environ['AUTOGRAPH_VERBOSITY'] = '5'
# Verbosity is now 5

tf.autograph.set_verbosity(0)
# Verbosity is now 0

os.environ['AUTOGRAPH_VERBOSITY'] = '1'
# No effect, because set_verbosity was already called.

Logs entries are output to absl's default output, with INFO level. Logs can be mirrored to stdout by using the alsologtostdout argument. Mirroring is enabled by default when Python runs in interactive mode.

level int, the verbosity level; larger values specify increased verbosity; 0 means no logging. When reporting bugs, it is recommended to set this value to a larger number, like 10.
alsologtostdout bool, whether to also output log messages to sys.stdout.
