tf.extract_image_patches的实现

本文介绍了tf.extract_image_patches的实现的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ tf.extract_image_patches 的实现在哪里？我检查了我找不到的tensorflow存储库。Where is the implementation of tf.extract_image_patches? I checked the tensorflow repository I could not find it.文件 tensorflow / core / kernels / extract_image_patches_op.cc推荐答案这是一个有趣的问题。路径如下：That's an interesting question. The path is as follows: Python tf.extract_image_patches 函数在生成的文件 tensorflow / python / ops /中实现gen_array_ops.py ，它调用 ExtractImagePatches 本机操作。Python tf.extract_image_patches function is implemented in the generated file tensorflow/python/ops/gen_array_ops.py, which invokes "ExtractImagePatches" native op.此操作由ExtractImagePatchesOp 实现＃L50 rel = noreferrer>对于CPU和GPU设备而言， core / kernels / extract_image_patches_op.cc 。主要调用是 functor :: ExtractImagePatchesForward ...This op is implemented by ExtractImagePatchesOp in core/kernels/extract_image_patches_op.cc for both CPU and GPU devices. The main call is functor::ExtractImagePatchesForward... ...，它在 core / kernels / extract_image_patches_op。 h 。实际的逻辑委托给输入张量的 :: extract_image_patches（）方法。张量的类型是 TTypes< T，4> :: ConstTensor ，它是 Eigen :: TensorMap > $code> core / framework / tensor_types。 h 。... which is defined in core/kernels/extract_image_patches_op.h. The actual logic is delegated to the ::extract_image_patches() method of the input tensor. The tensor's type is TTypes<T, 4>::ConstTensor, which is a typedef of Eigen::TensorMap core/framework/tensor_types.h.此时，它已脱离张量流源基本，因为 Eigen 来自第三方特征库（ GitHub镜像）。它的源代码有些轻松下载并链接到tensorflow ，但是现在我们对 Eigen :: TensorMap :: extract_image_patches（）函数。At this point, it's getting out of tensorflow source base, because Eigen is from the third-party eigen library (GitHub mirror). Its source code is somewhat non-trivially downloaded and linked to tensorflow, but right now we are interested in Eigen::TensorMap::extract_image_patches() function. 它在 eigen / unsupported / Eigen / CXX11 / src / Tensor / TensorBase.h 文件并应用 TensorImagePatchOp ... ...可以在 eigen / unsupported / Eigen / CXXens /TensorImagePatch.h 。最后，此函子不再进一步委托它，即实际的实现。... which can be found in eigen/unsupported/Eigen/CXX11/src/Tensor/TensorImagePatch.h. Finally, this functor doesn't delegate it further, i.e. the actual implementation.请注意， Eigen 库的特定版本可能有所不同在不同版本的tensorflow中，您应该在bazel配置中进行检查。Note that particular version of Eigen library may be different in different builds of tensorflow, which you should check in the bazel config. 这篇关于tf.extract_image_patches的实现的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
