在 bazel 构建系统中配置相互依赖的项目（例如 tensorflow）的正确方法，以便 proto 导入按原样工作？

Question

如标题所示，我运行遇到了一个问题，即 proto import 语句似乎与正确的路径不相关。具体来说，考虑目录中的目录结构（我们称之为 ~/base）：

`>> tree -L 1
├── models
├── my-lib
|     ├── nlp
|        ├── BUILD
|        └── nlp_parser.cc
|     └── WORKSPACE
├── serving
└── tensorflow

对于那些不熟悉的人，models（如 https://github.com/tensorflow/models/) has tensorflow (https://github.com/tensorflow/tensorflow）作为一个 git 子模块，serving 也是如此。由于这一点加上 tensorflow 的 git 子模块在不同的提交上有时不兼容，我从项目中删除了 git 子模块并将它们符号链接到最顶层目录的 tensorflow repo这样我就可以只管理一个张量流回购而不是 3 个。也就是说，我已经完成了以下操作：

`cd models/syntaxnet; rm -rf tensorflow; ln -s ../../tensorflow/ .; cd -`

`cd serving; rm -rf tensorflow tf_models; ln -s ../tensorflow/ .; ln -s ../models .`

现在我想在 my-lib 内构建一个依赖于 serving、tensorflow 和 models 的目标。我将这些作为本地存储库添加到我的 WORKSPACE 中，如下所示 (cat my-lib/WORKSPACE):

workspace(name = "myworkspace")

local_repository(
  name = "org_tensorflow",
  path = __workspace_dir__ + "/../tensorflow",
)

local_repository(
  name = "syntaxnet",
  path = __workspace_dir__ + "/../models/syntaxnet",
)

local_repository(
  name = "tf_serving",
  path = __workspace_dir__ + "/../serving",
)

load('@org_tensorflow//tensorflow:workspace.bzl', 'tf_workspace')
tf_workspace("~/base/tensorflow", "@org_tensorflow")

# ===== gRPC dependencies =====

bind(
    name = "libssl",
    actual = "@boringssl_git//:ssl",
)
bind(
    name = "zlib",
    actual = "@zlib_archive//:zlib",
)

这是我的构建文件 (cat my-lib/nlp/BUILD):

load("@tf_serving//tensorflow_serving:serving.bzl", "serving_proto_library")

cc_binary(
  name = "nlp_parser",
  srcs = [ "nlp_parser.cc" ],
  linkopts = ["-lm"],
  deps = [
        "@org_tensorflow//tensorflow/core:core_cpu",
        "@org_tensorflow//tensorflow/core:framework",
        "@org_tensorflow//tensorflow/core:lib",
        "@org_tensorflow//tensorflow/core:protos_all_cc",
        "@org_tensorflow//tensorflow/core:tensorflow",
        "@syntaxnet//syntaxnet:parser_ops_cc",
        "@syntaxnet//syntaxnet:sentence_proto",
        "@tf_serving//tensorflow_serving/servables/tensorflow:session_bundle_config_proto",
        "@tf_serving//tensorflow_serving/servables/tensorflow:session_bundle_factory",
        "@org_tensorflow//tensorflow/contrib/session_bundle",
        "@org_tensorflow//tensorflow/contrib/session_bundle:signature",
  ],
)

最后，这是构建的输出 (cd my-lib; bazel build nlp/nlp_parser --verbose_failures)：

在 WORKSPACE 中将模块添加为 local_repository 以便 proto 导入工作的正确方法是什么？

Answer 1

在 OS X 上构建依赖于 tensorflow 的项目后，我尝试构建我的项目后遇到了类似的问题。最终对我有用的是禁用沙盒--spawn_strategy=standalone
