在TensorFlow編譯後使用Bazel後,我試圖運行Image Recognition with the C++ API tutorial並出現Illegal instruction錯誤,同時嘗試執行label_image在TensorFlow上運行C++ inception-v3時出現非法指令錯誤

我做了以下步驟:

# After installing the bazel dependencies, I get the bazel installer 
$ mkdir ~/bazel-download && cd ~/bazel-download 
$ wget https://github.com/bazelbuild/bazel/releases/download/0.3.0/bazel-0.3.0-installer-linux-x86_64.sh -O bazel-0.3.0-installer-linux-x86_64.sh 

$ chmod +x bazel-0.3.0-installer-linux-x86_64.sh 
# Install bazel in ~/bin 
$ ./bazel-0.3.0-installer-linux-x86_64.sh --user 

# Add bazel to the path, if not done already 
$ printf '\nexport PATH=$PATH:"~/bin/"\n' >> ~/.bashrc 

# Before this, I create a new terminal to refresh the bash PATH 
$ mkdir ~/inceptionV3 && cd ~/inceptionV3 
# Get a stable version of TensorFlow 
$ git clone https://github.com/tensorflow/tensorflow -b r0.9 
$ cd tensorflow 

# Add the InceptionV3 data/models for the C++ api 
$ wget https://storage.googleapis.com/download.tensorflow.org/models/inception_dec_2015.zip -O tensorflow/examples/label_image/data/inception_dec_2015.zip 
$ unzip tensorflow/examples/label_image/data/inception_dec_2015.zip -d tensorflow/examples/label_image/data/ 

# Configure tensorflow: set python path, no Google Cloud Platform support, no GPU support 
$ ./configure 
# Run bazel build with the allocated resources 
$ bazel build -c opt --copt=-mavx --verbose_failures --local_resources 2048,2.0,1.0 -j 1 tensorflow/examples/label_image/... 

# -- Here's the last log output from bazel -- 
INFO: From Compiling tensorflow/core/common_runtime/function.cc:

       } else if (rets->size() != ctx->num_outputs()) { 
                  ^

# Look like there's no error during the compilation, but now, if I run the generated executable: 
$ ./bazel-bin/tensorflow/examples/label_image/label_image 
Illegal instruction 

另外,我上泊塢運行具有一個Ubuntu 14.04.4 LTS x86_64的容器(GCC /克++版本是4.8.4)。

我試着用其他設置運行此操作,例如使用apt-get install for bazel,但在運行帶有新編譯的可執行文件後仍然出現Illegal instruction錯誤。

這就是說,本教程的Python部分工作正常(使用Python 2.7.6)。任何想法如何解決問題的C + + API?

edit1 :(增加關於cpu的更多信息) 這是我從/proc/cpuinfo得到的輸出。

EDIT2:(試圖調試tensorflow) 使用這個命令編譯:

$ bazel build -c dbg --strip=always --copt=-mavx --verbose_failures --local_resources 2048,2.0,1.0 -j 1 tensorflow/examples/label_image/... 

我試着用GDB調試:

$ -q bazel-bin/tensorflow/examples/label_image/label_image

到目前爲止,由於Illegal instruction錯誤造成通過一個SIGILL信號,那麼我猜我目前的體系結構與生成的機器代碼不匹配。但是,我不確定如何處理這個特定的問題。

非法指令與您的處理器有關,所以您應該提及它。 –

好吧,我添加了/ proc/cpuinfo的輸出,它與我的主機系統和docker容器都匹配。 – antogerva

哦,這很奇怪,用i7你不應該得到這樣的錯誤,現在在gdb下運行該命令並生成回溯,它可能會告訴哪條指令是非法的,並且會指出問題。 –

經過幾次搜索,似乎--copt=-mavx實際上是傳遞給gcc的參數,以優化OSX機器上的架構as pointed over here。所以它不可能在我的linux「PC」機器上工作。
