任何人都在使用Nvidia Tegra X1进行张量调整？
我发现一些消息来源表明它可能存在于TK1上，或者TX1上存在严重的黑客攻击/错误，但还没有确定的配方。
我正在使用Jetson 2.3安装但尚未使用它 - 任何提示最受欢迎。

TensorFlow R0.9使用Bazel 0.2.1，CUDA 8.0，CUDNN5.1，L4T24.2和新安装的JetPack 2.3在TX1上运行。我使用BN，Sigmoid，ReLU等基本的MLP，Conv和LSTM网络进行了测试，但没有任何错误。我删除了sparse_matmul_op，但认为编译应该完全可操作。其中许多步骤直接来自MaxCuda's excellent blog，非常感谢他们的提供。
计划继续锤击R0.10 / R0.11（gRPC二进制文件现在正在阻止Bazel 0.3.0），但在此之前我想发布了R0.9公式。如下：
首先得到java
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
安装其他一些代表
sudo apt-get install git zip unzip autoconf automake libtool curl zlib1g-dev maven swig
需要自己制作protobuf 3.0.0-beta-2 jar
git clone https://github.com/google/protobuf.git
cd protobuf
# autogen.sh downloads broken gmock.zip in d5fb408d
git checkout master
./autogen.sh
git checkout d5fb408d
./configure --prefix=/usr
make -j 4
sudo make install
cd java
mvn package
得到bazel。我们想要版本0.2.1，它不需要gRPC二进制文件，不像0.3.0我还无法构建（可能很快！）
git clone https://github.com/bazelbuild/bazel.git
cd bazel
git checkout 0.2.1
cp /usr/bin/protoc third_party/protobuf/protoc-linux-arm32.exe
cp ../protobuf/java/target/protobuf-java-3.0.0-beta-2.jar third_party/protobuf/protobuf-java-3.0.0-beta-1.jar
需要编辑bazel文件以将aarch64识别为ARM

现在编译
./compile.sh
然后安装
sudo cp output/bazel /usr/local/bin
获得张量流R0.9。高于R0.9需要Bazel 0.3.0，由于gRPC问题，我还没有想出如何构建。
git clone -b r0.9 https://github.com/tensorflow/tensorflow.git
建立一次。它会失败，但现在你有了bazel .cache目录，你可以放置更新的config.guess＆amp; config.sub文件，它将显示您正在运行的架构
./configure

关注Dwight Crow's answer但使用8 GB交换文件并使用以下命令从全新安装的JetPack 2.3在Jetson TX1上成功构建TensorFlow 0.9：
self
除了启用GPU支持外，我使用了TensorFlow的bazel build -c opt --local_resources 3072,4.0,1.0 --verbose_failures --config=cuda //tensorflow/tools/pip_package:build_pip_package脚本的默认设置。
我的构建至少需要6个小时。如果您使用SSD而不是USB驱动器，它会更快。
./configure我使用this USB drive来存储我的交换文件。
我看到我的系统使用的内存最多是7.7 GB（Mem上为3.8 GB，Swap上为3.9 GB）。我见过的最多交换内存是4.4 GB。我使用# Create a swapfile for Ubuntu at the current directory location
fallocate -l *G swapfile
# List out the file
ls -lh swapfile
# Change permissions so that only root can use it
chmod 600 swapfile
# List out the file
ls -lh swapfile
# Set up the Linux swap area
mkswap swapfile
# Now start using the swapfile
sudo swapon swapfile
# Show that it's now being used
swapon -s
来查看内存使用情况。
free -h感谢Dwight Crow（指南），elirex（bazel选项值和free -h），tylerfox（交换文件构思和local_resources选项），帮助他们的每个人，以及每个人在the Github issue thread。
交换文件脚本改编自JetsonHack's gist。
