禁用GPU版本TensorFlow,切换到CPU版本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

如果安装了GPU,默认使用GPU版本的TensorFlow
