c++ - 在树莓派上构建 libtensorflow.so 时出错

Question

问题陈述:我想使用 Golang TensorFlow 在 Raspberry PI 3 中运行我的模型。要使用 TensorFlow，我需要有 libtensorflow.so 和 libtensorflow_framework.so C++ 共享库。

我尝试使用 bazel v0.20.0 从源代码构建，但遇到了问题，最后出错了。

目标: 为 tensorflow r1.11.0 或 r1.12.0 构建 libtensorflow.so

感谢任何帮助。

I found solution:
Couple of things to take care.

***For Tensorflow < v1.5***
Follow instruction here: https://blog.meinside.pe.kr/TensorFlow-and-Go-on-Raspberry-Pi/

***For Tensorflow v1.11.0 - v1.12.0***
Install bazel:
1. Download bazel from link: https://github.com/bazelbuild/bazel/releases
for specific architecture.
2. Install bazel
chmod +x bazel-<version>-installer-linux-<arch>.sh
./bazel-<version>-installer-linux-<arch>.sh --user
Install protobuf:
1. Build/Install protobuf from source.
https://github.com/protocolbuffers/protobuf/blob/master/src/README.md
Build Tensorflow:
1. Git clone
git clone https://github.com/tensorflow/tensorflow.git
2. Check and remove build from specific tensorflow version
go to: tensorflow/tensorflow/tools/ci_build/install/*_toolchain.sh [specific to your linux type and arch]
remove the bazel build and installation like as follows
look for the line: **rm -rf /usr/local/bin/bazel** and remove
and remove **bazel** from line **apt-get install -y ...**

then run 
CI_DOCKER_EXTRA_PARAMS="-e CI_BUILD_PYTHON=python3 -e CROSSTOOL_PYTHON_INCLUDE_PATH=/usr/include/python3.6" tensorflow/tools/ci_build/ci_build.sh PI tensorflow/tools/ci_build/pi/build_raspberry_pi.sh

or 

tensorflow/tools/ci_build/ci_build.sh PI tensorflow/tools/ci_build/pi/build_raspberry_pi.sh 

or 

tensorflow/tools/ci_build/ci_build.sh PI tensorflow/tools/ci_build/pi/build_raspberry_pi.sh PI_ONE

Output:
Output can be found here:
