Reduce console verbosity

问题

I am running some training and prediction with Keras/TensorFlow and I get some OMP information that I do not need.

2019-05-20 12:11:45.625897: I tensorflow/core/common_runtime/process_util.cc:71] Creating new thread pool with default inter op setting: 2. Tune using inter_op_parallelism_threads for best p
erformance.

OMP: Info #250: KMP_AFFINITY: pid 22357 tid 22438 thread 12 bound to OS proc set 0

How can I remove this extra verbosity?

回答1:

EDIT: As (the vastly more qualified to talk about this topic than me) Jim Cownie points out, this output appears to be due to having KMP_AFFINITY defined with the attribute verbose. See The KMP_AFFINITY Environment Variable and set the environment variable accordingly (the default value is noverbose,respect,granularity=core,none,0,0).

(likely wrong information below)

I think those messages should go away if you disable the OpenMP warnings setting the environment variable KMP_WARNINGS to off or 0. From a shell:

$ KMP_WARNINGS=off python program.py

Or from Python itself, before OpenMP is initialized:

import os
os.environ['KMP_WARNINGS'] = 'off'
