Tensorflow：Cuda 计算能力 3.0。最低要求的 Cuda 功能是 3.5

Question

我正在从源代码 （文档） 安装 tensorflow。

Cuda驱动版本：

 nvcc: NVIDIA (R) Cuda compiler driver
Cuda compilation tools, release 7.5, V7.5.17

当我运行以下命令时：

 bazel-bin/tensorflow/cc/tutorials_example_trainer --use_gpu

它给了我以下错误：

我已经安装了 Tensorflow 修订版 1.8。它推荐CUDA 9.0。我正在使用具有 CUDA 计算能力 3.0 的 GTX 650M 卡，现在可以正常工作了。操作系统是 ubuntu 18.04。下面是详细步骤：

安装依赖项

我已经为我的 opencv 3.4 编译包含了 ffmpeg 和一些相关的包，如果不需要，请不要安装运行以下命令：

 sudo apt-get update
sudo apt-get dist-upgrade -y
sudo apt-get autoremove -y
sudo apt-get upgrade
sudo add-apt-repository ppa:jonathonf/ffmpeg-3 -y
sudo apt-get update
sudo apt-get install build-essential -y

sudo python get-pip.py
sudo pip install -U pip
sudo pip install -U numpy
sudo pip install -U pandas
sudo pip install -U wheel
sudo pip install -U six

安装 nvidia 驱动程序

运行以下命令：

 sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-390 -y

重新启动并运行以下命令，它应该会为您提供如下图所示的详细信息：

gcc-6 和 g++-6 检查。

CUDA 9.0 需要 gcc-6 和 g++-6，运行以下命令：

 cd /usr/bin
sudo rm -rf gcc gcc-ar gcc-nm gcc-ranlib g++
sudo ln -s gcc-6 gcc
sudo ln -s gcc-ar-6 gcc-ar
sudo ln -s gcc-nm-6 gcc-nm
sudo ln -s gcc-ranlib-6 gcc-ranlib
sudo ln -s g++-6 g++

安装 CUDA 9.0

转到 https://developer.nvidia.com/cuda-90-download-archive 。选择选项：Linux->x86_64->Ubuntu->17.04->deb(local)。下载主文件和两个补丁。运行以下命令：

 sudo dpkg -i cuda-repo-ubuntu1704-9-0-local_9.0.176-1_amd64.deb
sudo apt-key add /var/cuda-repo-9-0-local/7fa2af80.pub
sudo apt-get update
sudo apt-get install cuda

导航到您PC上的第一个补丁并双击它，它会自动执行，第二个补丁也是如此。

将以下内容添加到您的 ~/.bashrc 文件中并重新启动它：

 export PATH=/usr/local/cuda-9.0/bin${PATH:+:$PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-9.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

为 CUDA 9.0 安装 cudnn 7.1.4

从 https://developer.nvidia.com/cudnn 下载 tar 文件并将其解压缩到您的下载文件夹下载需要 nvidia 开发的登录名，免费注册运行以下命令：

 cd ~/Downloads/cudnn-9.0-linux-x64-v7.1/cuda
sudo cp include/* /usr/local/cuda/include/
sudo cp lib64/libcudnn.so.7.1.4 lib64/libcudnn_static.a /usr/local/cuda/lib64/
cd /usr/lib/x86_64-linux-gnu
sudo ln -s libcudnn.so.7.1.4 libcudnn.so.7
sudo ln -s libcudnn.so.7 libcudnn.so

为 CUDA 9.0 安装 NCCL 2.2.12

从 https://developer.nvidia.com/nccl 下载 tar 文件并将其解压缩到您的下载文件夹下载需要 nvidia 开发的登录名，免费注册运行以下命令：

 sudo mkdir -p /usr/local/cuda/nccl/lib /usr/local/cuda/nccl/include
cd ~/Downloads/nccl-repo-ubuntu1604-2.2.12-ga-cuda9.0_1-1_amd64/
sudo cp *.txt /usr/local/cuda/nccl
sudo cp include/*.h /usr/include/
sudo cp lib/libnccl.so.2.1.15 lib/libnccl_static.a /usr/lib/x86_64-linux-gnu/
sudo ln -s /usr/include/nccl.h /usr/local/cuda/nccl/include/nccl.h
cd /usr/lib/x86_64-linux-gnu
sudo ln -s libnccl.so.2.1.15 libnccl.so.2
sudo ln -s libnccl.so.2 libnccl.so
for i in libnccl*; do sudo ln -s /usr/lib/x86_64-linux-gnu/$i /usr/local/cuda/nccl/lib/$i; done

安装 Bazel（推荐手动安装 bazel，参考： https ://docs.bazel.build/versions/master/install-ubuntu.html#install-with-installer-ubuntu）

从 https://github.com/bazelbuild/bazel/releases 下载“bazel-0.13.1-installer-darwin-x86_64.sh”运行以下命令：

 chmod +x bazel-0.13.1-installer-darwin-x86_64.sh
./bazel-0.13.1-installer-darwin-x86_64.sh --user
export PATH="$PATH:$HOME/bin"

编译 Tensorflow

我们将使用 CUDA、XLA JIT（哦，是的）和 jemalloc 作为 malloc 支持进行编译。所以我们对这些事情输入是。运行以下命令并按照运行配置中的描述回答查询

 --config=mkl          # Build with MKL support.

 --config=monolithic   # Config for mostly static monolithic build.

Configuration finished

现在要编译 tensorflow，运行下面的命令，这是超级 RAM 消耗，需要时间。如果您有大量 RAM，您可以从下面的行中删除“–local_resources 2048,.5,1.0”，否则这将适用于 2 GB 的 RAM

 bazel build --config=opt --config=cuda --local_resources 2048,.5,1.0 //tensorflow/tools/pip_package:build_pip_package

编译完成后，您将看到如下图所示的内容，确认编译成功

构建 wheel 文件，在下面运行：

 bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg

使用pip安装生成的wheel文件

sudo pip install /tmp/tensorflow_pkg/tensorflow*.whl

要在设备上探索，现在可以运行 tensorflow，下图是 ipython 终端上的展示
