关闭Tensorflow调试信息开关

通过调试信息，我指的是TensorFlow在我的终端中显示的关于加载的库和找到的设备等的信息，而不是Python错误。

献给那些还在努力获得操作系统的人。environ解决方案的工作，检查这是放在你导入tensorflow在你的脚本，就像mwweb的答案:

import os
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '3'  # or any {'0', '1', '2'}
import tensorflow as tf

其他回答

通常的python3日志管理器为我工作tensorflow==1.11.0:

import logging
logging.getLogger('tensorflow').setLevel(logging.INFO)

为了兼容Tensorflow 2.0，你可以使用tf.get_logger

import logging
tf.get_logger().setLevel(logging.ERROR)

是的，我正在使用tf 2.0 beta，并想启用/禁用默认日志记录。tf1中的环境变量和方法。X似乎不再存在了。

我在PDB中发现了这个方法:

# close the TF2 logger
tf2logger = tf.get_logger()
tf2logger.error('Close TF2 logger handlers')
tf2logger.root.removeHandler(tf2logger.root.handlers[0])

然后添加自己的日志记录器API(在本例中是基于文件的)

logtf = logging.getLogger('DST')
logtf.setLevel(logging.DEBUG)

# file handler
logfile='/tmp/tf_s.log'
fh = logging.FileHandler(logfile)
fh.setFormatter( logging.Formatter('fh %(asctime)s %(name)s %(filename)s:%(lineno)d :%(message)s') )
logtf.addHandler(fh)
logtf.info('writing to %s', logfile)

我也遇到过这个问题(在tensorflow-0.10.0rc0上)，但无法通过建议的答案修复过多的鼻子测试日志问题。

我设法通过直接探测张量流记录器来解决这个问题。不是最正确的修复，但工作很好，只污染直接或间接导入tensorflow的测试文件:

# Place this before directly or indirectly importing tensorflow
import logging
logging.getLogger("tensorflow").setLevel(logging.WARNING)
