查看keras认得到的GPU

from keras import backend as K
K.tensorflow_backend._get_available_gpus()

Out[28]:

[‘/job:localhost/replica:0/task:0/device:GPU:0‘]

查看更详细device信息

from tensorflow.python.client import device_lib
import tensorflow as tf

print(device_lib.list_local_devices())
print(tf.test.is_built_with_cuda())

output:

 [name: "/device:CPU:0"
device_type: "CPU"
memory_limit: 268435456
locality {
}
incarnation: 9443078288448539683

device_type: "XLA_CPU"

]
True
 
查看正在使用的GPU
import tensorflow as tf
print (tf.__version__)
if tf.test.gpu_device_name():
    print(Default GPU Device: {}.format(tf.test.gpu_device_name()))
else:
    print("Please install GPU version of TF")
 
 

output: 

1.13.1
Default GPU Device: /device:GPU:0
