我正在从源代码构建TF并且在python中包含contrib没有任何问题。当我尝试使用以下错误访问此模块时出现段错误:

看起来问题与protobuf相关,但这很难诊断。

1 个答案:

答案 0 :(得分:1)

在使用Xcode 9.3在MacOS 10.13.4上进行编译时,我观察到同样的问题。

问题在于,protobuf静态链接到libtensorflow_framework.so,但也导入_single_image_random_dot_stereograms.solibforestprotos.so,在导入contrib时会加载。

这是一个相关的protobuf issue

该问题中的注释表示在使用Xcode 8.3或更高版本进行编译时会出现问题,因此我假设官方tensorflow二进制文件有效,因为它是使用旧版本构建的。

作为解决方法,我已在@protobuf_archive//:protobuf/tensorflow/tensorflow/tensorflow/contrib/image/BUILD中本地删除了“/tensorflow/tensorflow/tensorflow/contrib/tensor_forest/BUILD”的两个出现。

对于我在python中进行本地实验的用例,这似乎没有破坏任何东西。
