我目前正在尝试首次通过 tensorflow XLA 提前编译工作流程,并且在尝试构建包含 AOT 编译对象的最终可执行二进制文件时遇到了问题。
我已经使用这里的教程来生成test_graph_tfgather.pb
和test_graph_tfgather.config.pbtxt
文件。然后我tfcompile
直接使用该工具来制作MyClass.o
和MyClass.h
. 到目前为止,一切都很好。
我现在正在构建一个包含此编译模型的简单 makefile 项目,但我遇到了一些与 Eigen 相关的错误。这可能是由于我的计算机上安装了不同版本的 eigen3 造成的吗?由于本征错误,我还不得不注释掉 Eigen::ThreadPool 行,因此某些版本未匹配可能是问题所在。以前有没有人见过这个问题,或者有没有人知道如何让它工作?
谢谢。
