tensorflow 服务构建依赖于大型 tensorflow；但我已经成功构建了 tensorflow。所以我想用它。我做这些事情：我更改了张量流服务 WORKSPACE(org: https://github.com/tensorflow/serving/blob/master/WORKSPACE)

workspace(name = "tf_serving")

# To update TensorFlow to a new revision.
# 1. Update the 'git_commit' args below to include the new git hash.
# 2. Get the sha256 hash of the archive with a command such as...
#    curl -L https://github.com/tensorflow/tensorflow/archive/<git hash>.tar.gz | sha256sum
#    and update the 'sha256' arg with the result.
# 3. Request the new archive to be mirrored on mirror.bazel.build for more
#    reliable downloads.
#load("//tensorflow_serving:repo.bzl", "tensorflow_http_archive")

#tensorflow_http_archive(
#    name = "org_tensorflow",
#    sha256 = "0f4b8375de30c54cc3233bc40e04742dab0ffe007acf8391651c6adb62be89f8",
#    git_commit = "2ea398b12ed18b6c51e09f363021c6aa306c5179",
#)

local_repository(
    name = "org_tensorflow",
    path = "/vagrant/tf/tensorflow/",
)


# TensorFlow depends on "io_bazel_rules_closure" so we need this here.
# Needs to be kept in sync with the same target in TensorFlow's WORKSPACE file.
http_archive(
    name = "io_bazel_rules_closure",
    sha256 = "a38539c5b5c358548e75b44141b4ab637bba7c4dc02b46b1f62a96d6433f56ae",
    strip_prefix = "rules_closure-dbb96841cc0a5fb2664c37822803b06dab20c7d1",
    urls = [
        "https://mirror.bazel.build/github.com/bazelbuild/rules_closure/archive/dbb96841cc0a5fb2664c37822803b06dab20c7d1.tar.gz",
        "https://github.com/bazelbuild/rules_closure/archive/dbb96841cc0a5fb2664c37822803b06dab20c7d1.tar.gz",  # 2018-04-13
    ],
)

# Please add all new TensorFlow Serving dependencies in workspace.bzl.
load("//tensorflow_serving:workspace.bzl", "tf_serving_workspace")

tf_serving_workspace()

# Specify the minimum required bazel version.
load("@org_tensorflow//tensorflow:version_check.bzl", "check_bazel_version_at_least")

check_bazel_version_at_least("0.15.0")

但是我用这个命令错误构建：

应该如何使用本地 tensorflow 成功构建服务？谢谢！

【解决方案1】：

您应该提高 docker build 资源 CPU 和内存。我在笔记本电脑上对 docker 进行了 4 vcpu 和 4 Gig ram 升级，但是在构建 tensorflow 服务映像时，您需要使用此选项将 Bazzel C 编译器限制为 2048 Meg 内存

https://www.tensorflow.org/serving/docker

docker build --pull --build-arg TF_SERVING_BUILD_OPTIONS="--copt=-mavx \
  --cxxopt=-D_GLIBCXX_USE_CXX11_ABI=0 --local_resources 2048,.5,1.0" -t \
  $USER/tensorflow-serving-devel -f Dockerfile.devel .

还需要将 Bazel 的版本升级到 20 才能使构建工作。在你的 docker 文件中

设置 Bazel augmenter 版本 20 倒编译器 tensorflow

  

   Set up Bazel augmenter version 20 pour compiler tensorflow
    # Need >= 0.15.0 so bazel compiles work with docker bind mounts.
    ENV BAZEL_VERSION 0.20.0
    WORKDIR /
    RUN mkdir /bazel && \
        cd /bazel && \
        curl -H "User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/57.0.2987.133 Safari/537.36" -fSsL -O https://github.com/bazelbuild/bazel/releases/download/$BAZEL_VERSION/bazel-$BAZEL_VERSION-installer-linux-x86_64.sh && \
        curl -H "User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/57.0.2987.133 Safari/537.36" -fSsL -o /bazel/LICENSE.txt https://raw.githubusercontent.com/bazelbuild/bazel/master/LICENSE && \
        chmod +x bazel-*.sh && \
        ./bazel-$BAZEL_VERSION-installer-linux-x86_64.sh && \
        cd / && \
        rm -f /bazel/bazel-$BAZEL_VERSION-installer-linux-x86_64.sh

这里是名为 dockerbuild.txt 的整个 docker 文件和 docker build 命令

docker build --pull --build-arg TF_SERVING_BUILD_OPTIONS="--copt=-mavx --cxxopt=-D_GLIBCXX_USE_CXX11_ABI=0 --local_resources 2048,.5,1.0" -f dockerbuild.txt .
