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
