在Nvidia TX2上安装Cuda8.0+Cudnn5.1+TensorFlow1.2+OpenCV3.2

工具

宿主机（host）：ubuntu14.04、至少50GB存储空间
Jetpack3.0：软件下载地址、文档地址

因为只有Jetpack3.0包含cuda8.0和cudnn5.1，而Jetpack3.0只能运行在ubuntu14.04上（亲测16.04有问题会导致失败）

安装Jetpack3.0，并对TX2进行刷机和安装Cuda等框架

保证宿主机和tx2在同一局域网下，按照官方文档和Jetpak的提示执行即可，很简单。

注意事项：

（1）如果在host上安装cuda toolkit出现错误（类似held package等）的时候，换一下ubuntu的更新源（推荐163源）就可以了。

（2）期间如果出现host机提示determining IP …. （卡很久）之类的提示，可以关掉，然后重新来，flash system image那个选择no action，之后就会出现手动配置板子的IP和用户密码的选项。

安装TensorFlow1.2

我编译好的whl文件 —— 百度网盘提取码：n1sz

可以尝试直接使用我编译好的whl文件（直接跳到安装whl文件这一步）

不保证可用，保险起见如果有时间的话最好还是执行下面的步骤。

安装依赖

sudo add-apt-repository ppa:webupd8team/javasudo apt-get updatesudo apt-get install oracle-java8-installer -ysudo apt-get install zip unzip autoconf automake libtool curl zlib1g-dev maven -ysudo apt install python3-numpy python3-dev python3-pip python3-wheel

安装bazel

bazel_version=0.5.1wget https://github.com/bazelbuild/bazel/releases/download/$bazel_version/bazel-$bazel_version-dist.zipunzip bazel-$bazel_version-dist.zip -d bazel-distsudo chmod -R ug+rwx bazel-distcd bazel-dist#编译这一步很耗时，约20~30分钟./compile.sh sudo cp output/bazel /usr/local/bin

下载TensorFlow源码

cd ~git clone --recursive https://github.com/tensorflow/tensorflow.gitcd tensorflowgit checkout v1.2.0

修改tensorflow/workspace.bzl,更改为如下：

#注意是eigen_archive节点native.new_http_archive(      name = "eigen_archive",      urls = [          "http://mirror.bazel.build/bitbucket.org/eigen/eigen/get/d781c1de9834.tar.gz",          "https://bitbucket.org/eigen/eigen/get/d781c1de9834.tar.gz",      ],      sha256 = "a34b208da6ec18fa8da963369e166e4a368612c14d956dd2f9d7072904675d9b",      strip_prefix = "eigen-eigen-d781c1de9834",      build_file = str(Label("//third_party:eigen.BUILD")),  )

配置编译变量

export PYTHON_BIN_PATH=$(which python3)# No Google Cloud Platform supportexport TF_NEED_GCP=0# No Hadoop file system supportexport TF_NEED_HDFS=0# Use CUDAexport TF_NEED_CUDA=1# Setup gcc ; just use the defaultexport GCC_HOST_COMPILER_PATH=$(which gcc)# TF CUDA Version export TF_CUDA_VERSION=8.0# CUDA pathexport CUDA_TOOLKIT_PATH=/usr/local/cuda# cuDNNexport TF_CUDNN_VERSION=5.1.10export CUDNN_INSTALL_PATH=/usr/lib/aarch64-linux-gnu# CUDA compute capabilityexport TF_CUDA_COMPUTE_CAPABILITIES=6.2export CC_OPT_FLAGS=-march=nativeexport TF_NEED_JEMALLOC=1export TF_NEED_OPENCL=0export TF_ENABLE_XLA=1

编译、生成、打包

#这一步有提示的话，直接enter就行，不用理./configure#这一步巨巨巨耗时！约3小时bazel build -c opt --verbose_failures --config=cuda //tensorflow/tools/pip_package:build_pip_packagebazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkgmv /tmp/tensorflow_pkg/tensorflow-1.2.0*-linux_aarch64.whl ~

安装whl文件

#有可能提示版本问题，参考错误提示修改#这步也很耗时，需要耐心等待pip3 install ~/tensorflow-1.2.0-cp35-cp35m-linux_aarch64.whl

安装这一步会在“Running setup.py bdist_wheel for numpy …”卡住很久，需要一点耐心

测试脚本testtf.py

#!/usr/bin/env python import tensorflow as tfhello = tf.constant('Hello, TensorFlow!')sess = tf.Session()print(sess.run(hello))

运行：

python3 testtf.py

结果：
