tensorflow - 使用 Keras 对 GPU 进行推理

标签 tensorflow keras

我正在尝试使用我的 RTX 2060 Super 使用 Keras 进行预测。出于某种原因，它似乎在我的 CPU 上运行。
这是我用于调试的测试脚本:

import numpy as np
import tensorflow as tf
from keras import Sequential
from keras.layers import Conv2D, Flatten, Dense


def get_model():
    model = Sequential()
    model.add(Conv2D(32, (3, 3), input_shape=(6, 7, 3), activation='relu'))
    model.add(Conv2D(32, (3, 3), activation='relu'))
    model.add(Flatten())
    model.add(Dense(16, activation='relu'))
    model.add(Dense(16, activation='relu'))
    model.add(Dense(1, activation='tanh'))
    model.compile(optimizer='adam', loss='mean_squared_error', metrics=['accuracy'])
    return model


def test_gpu():
    model = get_model()
    arg = np.random.rand(10000, 6, 7, 3)
    with tf.device('gpu'):
        for i in range(10000):
            print(i)
            model.predict(arg)


if __name__ == '__main__':
    tf.config.experimental.list_physical_devices()
    tf.debugging.set_log_device_placement(True)
    test_gpu()
这是打印到控制台的结果:

这是一个屏幕截图，显示了我在任务管理器中的 CPU 和 GPU 利用率:
Task Manager Screenshot
任何帮助，将不胜感激!

最佳答案

在这里总结 Comments Section 中提到的要点( Answer Section )，并提供代码以检查 Tensorflow 是否正在使用下面的 GPU 以造福社区 。
我们不应该使用 Task Manager 来检查 GPU 是否正在使用 Tensorflow 。
相反，我们可以使用下面提到的代码:

import tensorflow as tf
print(tf.config.list_physical_devices('GPU'))
print('Default GPU Device: {}'.format(tf.test.gpu_device_name()))
print(tf.test.is_built_with_cuda())
如果 Tensorflow 使用 GPU ，则上述代码的输出将是:
[PhysicalDevice(name='/physical_device:GPU:0', device_type='GPU')]
Default GPU Device: /device:GPU:0
True
您还可以运行以下代码以了解 Tensorflow 使用的所有设备:
from tensorflow.python.client import device_lib
print(device_lib.list_local_devices())
在 Google Colab 中使用 Runtime 作为 GPU 运行时，上述代码的输出如下所示:
[name: "/device:CPU:0"
device_type: "CPU"
memory_limit: 268435456
locality {
}

, name: "/device:XLA_CPU:0"
device_type: "XLA_CPU"
memory_limit: 17179869184

physical_device_desc: "device: XLA_CPU device"

physical_device_desc: "device: XLA_GPU device"

memory_limit: 14648777152

  bus_id: 1
  links {
  }
}

physical_device_desc: "device: 0, name: Tesla T4, pci bus id: 0000:00:04.0, compute capability: 7.5"
]
您还可以使用命令 nvidia-smi 。
