Tensorflow不使用GPU(根据TensorBoard)

编辑:GTX 1070,ubuntu 16.04,git hash:3b75eb34ea2c4982fb80843be089f02d430faade

我在我自己的数据上重新训练inception模型 . 一切都很好,直到最后的命令:

bazel-bin/inception/flowers_train \
  --config=cuda \
  --train_dir="${TRAIN_DIR}" \
  --data_dir="${OUTPUT_DIRECTORY}" \
  --pretrained_model_checkpoint_path="${MODEL_PATH}" \
  --fine_tune=True \
  --initial_learning_rate=0.001 \
  --input_queue_memory_factor=1

根据日志, Tensorflow seems to be using the GPU

I tensorflow/core/common_runtime/gpu/gpu_device.cc:951] Found device 0 with properties:
name: GeForce GTX 1070

但是当我在TensorBoard中检查学习时, the net is using mainly the CPU (蓝色/设备:CPU:0,绿色/设备:GPU:0):

我试过这两个TensorFlow设置:

  • 从源代码安装nvidia-367驱动程序,CUDA8 8.0,cuDNN v5,来自主服务器的源代码(16/10/06 - r11?) . 编译为GPU使用:
bazel build -c opt --config=cuda //tensorflow/cc:tutorials_example_trainer
bazel-bin/tensorflow/cc/tutorials_example_trainer --use_gpu    
bazel build -c opt --config=cuda //tensorflow/tools/pip_package:build_pip_package
  • docker在具有GTX 1070 8Go的PC上使用Tensorflow的GPU映像
nvidia-docker run -it -p 8888:8888 -p 6006:6006 gcr.io/tensorflow/tensorflow:latest-gpu /bin/bash

有帮助吗?

    根据this issue,初始'tower'是正在执行大部分工作的地方 . 所以看起来很好 .

    除了还有一些奇怪的东西 . 运行 watch nvidia-smi 给出:

    GPU似乎被忽略了......
