无法制作 tensorflow Raspberry pi 示例

Question

我在 Raspberry Pi 3 上安装了 tensorflow，运行 Jessie，并通过 .whl 文件/python 2.7 的 pip 安装两种方式完成。：

https://github.com/samjabrahams/tensorflow-on-raspberry-pi

以及完整编译通过：

https://github.com/tensorflow/tensorflow/tree/master/tensorflow/contrib/makefile

两次安装（我在不同的操作系统映像上进行）都成功并且没有错误地完成。

接下来，我想从 tensorflow 的 git 存储库中编译官方的 Raspberry Pi 示例：

https://github.com/tensorflow/tensorflow/tree/master/tensorflow/contrib/pi_examples

但是，没有一个示例可以编译（无论是相机示例还是图像识别），都给出了相同的错误，Google 也没有告诉我任何信息：

还有：

如何定位/添加/编译“nsync_cv.h”？ 顺便说一句：

export HOST_NSYNC_LIB=`tensorflow/contrib/makefile/compile_nsync.sh`

给我：

g++ -M -std=c++11 -DNSYNC_USE_CPP11_TIMEPOINT -DNSYNC_ATOMIC_CPP11
-I../../platform/c++11 -I../../platform/gcc -I../../platform/posix -pthread -I../../public -I../../internal ../../internal/*.c ../../testing/*.c ../../platform/c++11/src/nsync_semaphore_mutex.cc
../../platform/c++11/src/per_thread_waiter.cc
../../platform/c++11/src/yield.cc
../../platform/c++11/src/time_rep_timespec.cc
../../platform/c++11/src/nsync_panic.cc \
          ../../platform/c++11/src/start_thread.cc > dependfile make: 'nsync.a' is up to date.

我曾经在 nvidia Jetson TX1 上使用 makefile 编译过 tensorflow，我可以通过在示例的 Makefile 中添加一些行来编译和运行示例：

1. 第 18 行之后：

   NSYNCLIBDIR := $(TFMAKEFILE_DIR)/downloads/nsync/builds/default.linux.c++11 !!!将文件夹 default.linux.c++11 更改为您的 libnsync.a 所在的位置!!!

   NSYNCLIBS := $(NSYNCLIBDIR)/libnsync.a

2. 第 26 行之后：

   NSYNC := $(TFMAKEFILE_DIR)/downloads/nsync/public/

3. 第 36 行之后：

   -L$(NSYNCLIBDIR) \

4. 第 43 行之后：

   -I$(NSYNC) \

5. 第 51 行之后：

   -lnsync \

6. 将第 72 行更改为：

   $(EXECUTABLE_NAME): $(EXECUTABLE_OBJS) $(TFLIBS) $(NSYNCLIBS)

希望它适用于这种变化，祝你好运:)
