Google Colab:GPU不使用tensorflow 1.12.0加载

Question

我正在尝试使用GPU 在Google Colab中训练一个模型

我做到了：

Edit→Notebook Settings
select GPU from the Hardware Accelerator drop-down

我安装了我的项目所需的这个特定版本：

tensorboard==1.12.2
tensorflow==1.12.0
Keras==2.2.4
Keras-Applications==1.0.6
Keras-Preprocessing==1.0.5

然后，当我运行时：

from tensorflow.python.client import device_lib
import tensorflow as to
print(device_lib.list_local_devices())
tf.test.is_gpu_available()

我得到：

[name: "/device:CPU:0"
device_type: "CPU"
memory_limit: 268435456
locality {
}
incarnation: 14765383507671724357
, name: "/device:XLA_CPU:0"
device_type: "XLA_CPU"
memory_limit: 17179869184
locality {
}
incarnation: 9874560735213287977
physical_device_desc: "device: XLA_CPU device"
]
False

如何使用GPU？
