张量流中Eigen的C ++使用 [英] C++ use of Eigen in tensorflow

问题描述

张量流与本征之间的关系是什么，特别是关于 tensor 数据结构?

What is the relation between tensorflow and Eigen, particularly regarding the tensor datastructures?

有些旧的报价(例如

There are some older quotations (e.g. here) which state that tensorflow is using Eigen extensively (afaik a tensorflow guy has extended the Eigen code). More recent tensorflow documentation, however, seems to not explicitly refer to Eigen.

两个 tensor 结构是否相同?它们是否正在同时更新?使用 Eigen :: tensor 而不是 tensorflow :: tensor 是否有(可能将来)不利?

Are the two tensor structures identical? Are they being updated concurrently? Is there any (possibly future) disadvantage in using the Eigen::tensor over the tensorflow::tensor?

推荐答案

tensorflow :: tensor 只是围绕 Eigen :: Tensor 的一个薄包装，其高级级别有限仅功能.您可以使用 tensor()方法访问 tensorflow :: tensor 的基础 Eigen :: Tensor .我想这些信息也可以解决您的最后两个问题.

tensorflow::tensor is just a thin wrapper around Eigen::Tensor with limited high-level features only. You can access to the underlying Eigen::Tensor of a tensorflow::tensor using the tensor() method. I guess that this information also solve your last two questions.
