问题

我试图修改this tutorial来编译用于C ++的TensorFlow网络。它目前要求您将网络文件复制到TensorFlow源代码中，以便找到依赖关系，但我宁愿不这样做。请注意，TensorFlow也是使用Bazel构建的。

这是我的BUILD文件：

cc_binary(
    name = "mnistpredict_keras",
    srcs = ["mnist_keras.cc", "MNIST.h"],
    deps = [
        "//tensorflow/core:tensorflow",
    ],
)

当我尝试运行$ bazel build :mnistpredict_keras时，我收到错误：

ERROR: /home/saubin/git/tf-keras-speed-test/loadgraph/BUILD:17:1: no such package 'tensorflow/core': BUILD file not found on package path and referenced by '//:mnistpredict_keras'.
ERROR: Analysis of target '//:mnistpredict_keras' failed; build aborted.
INFO: Elapsed time: 0.105s

显然，问题是我试图在我的文件夹~/git/tf-keras-speed-test/loadgraph中编译某些内容，但它无法找到依赖项//tensorflow/core:tensorflow。我如何正确地给出依赖的路径？ deps的文档似乎不存在。

尝试解决方案

向local_repository添加WORKSPACE：

local_repository(
    name = "tensorflow",
    path = "/home/saubin/src/tensorflow",
)

这没有改变。

尝试传递完整路径：

cc_binary(
    name = "mnistpredict_keras",
    srcs = ["mnist_keras.cc", "MNIST.h"],
    deps = [
        "/home/saubin/src/tensorflow/tensorflow/core:tensorflow",
    ],
)

但是我得到了同样的错误：

ERROR: /home/saubin/git/tf-keras-speed-test/loadgraph/BUILD:17:1: no such package 'tensorflow/core': BUILD file not found on package path and referenced by '//:mnistpredict_keras'.
ERROR: Analysis of target '//:mnistpredict_keras' failed; build aborted.
INFO: Elapsed time: 0.287s

将TensorFlow标记为external repository dependency：

cc_binary(
    name = "mnistpredict_keras",
    srcs = ["mnist_keras.cc", "MNIST.h"],
    deps = [
        "@tensorflow//tensorflow/core:tensorflow",
    ],
)

但这给了我这个错误：

WARNING: /home/saubin/.cache/bazel/_bazel_saubin/74f664e7cf53364557da8b57a716c919/external/tensorflow/WORKSPACE:1: Workspace name in /home/saubin/.cache/bazel/_bazel_saubin/74f664e7cf53364557da8b57a716c919/external/tensorflow/WORKSPACE (@org_tensorflow) does not match the name given in the repository's definition (@tensorflow); this will cause a build error in future versions.

Answer 1

外部依赖项的文档是https://bazel.build/versions/master/docs/external.html。

您要查找的语法是@tensorflow//tensorflow/core:tensorflow。

以//开头的标签引用当前存储库。以@reponame//开头的标签指的是 reponame 存储库。
