在Jetson TX2上安装tensorflow，需要在源码编译，至少我看到现在的教程都是在源码上编译，编译的时间会很久．　

源码编译安装tensorflow可以参考，这里主要说一些注意要项．

bazel和tensorflow

bazel 和tensorflow的版本注意不要太高，我这里就是bazel和tensorflow的版本选的太高，导致安装完出现问题，虽然不知道是不是依赖没有打完整的缘故，但是在这里还是建议选择低一些的版本．

我这边选择的是bazel-5.4，tensorflow1.3

内存空间不足

网上说编译tensorflow可能会出现内存空间不够用的情况，所以需要做一个交换文件，但是实际上我并没有碰到，但是还是记录一下

＃Create an 8GB swapfilefallocate -l 8G swapfile＃Change permission of the swapfilechmod 600 swapfile＃Create swap areamkswap swapfile＃Activate the swap areasudo swapon swapfile# deactive the swap aresudo swapoff swapfile＃Confirm swap area being usedswapon -s

修改tensorflow/stream_executor/cuda/cuda_gpu_executor.cc

在tensorflow/stream_executor/cuda/cuda_gpu_executor.cc中找到static int TryToReadNumaNode(conststring &pci_bus_id,intdevice_ordinal)这个函数，在最开始就添加一下内容

LOG(INFO) << "ARM has no NUMA node, hardcoding to return zero";return 0;

计算能力

在执行./configure的时候，如果要用到cuda会让你填Cuda compute capabilities，记得Jetson TX2的Cuda compute capabilities是6.2

这些错误是eigen的arm部分有问题，解决方法：

可以手工修改下，或者去下一个上述对arm修改过的3.3版本的Eigen去替换掉 ~/.cache/bazel/_bazel_ubuntu/5a48b4b8cc5de8b183f660553d84cc0b/external/eigen_archive/Eigen（那一长串的目录具体看你自己的）下的Eigen文件夹（）

手工修改方法是将tensorflow/workspace.bzl文件中的

native.new_http_archive(    name = "eigen_archive",    urls = [        "http://mirror.bazel.build/bitbucket.org/eigen/eigen/get/f3a22f35b044.tar.gz",        "https://bitbucket.org/eigen/eigen/get/f3a22f35b044.tar.gz",    ],    sha256 = "ca7beac153d4059c02c8fc59816c82d54ea47fe58365e8aded4082ded0b820c4",    strip_prefix = "eigen-eigen-f3a22f35b044",    build_file = str(Label("//third_party:eigen.BUILD")),)

替换成

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")),  )
