但是当我尝试检测列表中的本地设备时，只有CPU被检测到.

But when I try to detect the list local devices, only CPU got detected.

from tensorflow.python.client import device_lib
print(device_lib.list_local_devices())

[name: "/cpu:0"
device_type: "CPU"
memory_limit: 268435456
locality {
}
incarnation: 3303842605833347443
]

我是否需要设置其他内容才能将GPU用于Keras或Tensorflow?

Do I have to set something else to use the GPU for Keras or Tensorflow?

推荐答案

将pip install tensorflow-gpu或conda install tensorflow-gpu用于tensorflow的gpu版本.如果使用keras-gpu conda install -c anaconda keras-gpu命令将自动安装tensorflow-gpu版本.在执行这些命令之前，请确保已卸载常规的tensorflow.

Use pip install tensorflow-gpu or conda install tensorflow-gpu for gpu version of tensorflow. If you are using keras-gpu conda install -c anaconda keras-gpu command will automatically install the tensorflow-gpu version. Before doing these any command make sure that you uninstalled the normal tensorflow .
