禁用GPU版本TensorFlow

禁用GPU版本TensorFlow，切换到CPU版本TensorFlow。

如果安装了GPU，默认使用GPU版本的TensorFlow
禁用gpu版本TensorFlow，因为CUDA号码从0开始，这里直接让CUDA使用-1的GPU，自然就无法使用gpu了。
代码前面加入：

import os
os.environ["CUDA_VISIBLE_DEVICES"]="-1"    
import tensorflow as tf

Environment Variable Syntax    Results
CUDA_VISIBLE_DEVICES=1    Only device 1 will be seen
CUDA_VISIBLE_DEVICES=0,1    Devices 0 and 1 will be visible
CUDA_VISIBLE_DEVICES="0,1"    Same as above, quotation marks are optional
CUDA_VISIBLE_DEVICES=0,2,3    Devices 0, 2, 3 will be visible; device 1 is masked

tf 默认 logging.formatter

tf.logging formatter 默认
https://github.com/tensorflow/tensorflow/blob/33bb4fe143bf5f2d83343ca427afa314f84eb963/tensorflow/python/platform/tf_logging.py

import logging as _logging

      # Add the output handler.
      _handler = _logging.StreamHandler(_logging_target)
      _handler.setFormatter(_logging.Formatter(_logging.BASIC_FORMAT, None))
      logger.addHandler(_handler)
