来自 CMake 的 BUILD 文件，用于自定义操作张量流服务

Question

我是 C++ 新手，我跟随 this script 为句子构建了一个 custom_ops。从the description他们解释说，我运行cmake -DSPM_USE_BUILTIN_PROTOBUF=OFF -DSPM_ENABLE_TENSORFLOW_SHARED=ON ..后会得到一个BUILD文件

但是，在运行脚本后，我没有看到 BUILD 文件。我看到了-- Build files have been written to: /my_path/serving/tensorflow_serving/custom_ops/sentencepiece_processor/build。经过搜索，我发现 BUILD 文件是针对 Bazel 的，而 CMake 没有创建 BUILD 文件。如果是这种情况，我怎么能从 CMake 获得 BUILD 文件？谢谢。

Answer 1

好问题。我的同事打开了你提到的那个问题（stefanondisponibile 给出了一个了不起的解决方案）。我们最终需要一个带有 tensorflow serving + sentencepiece 的 docker 容器。这是 dockerfile。

要回答您的具体问题，您需要创建一个名为 BUILD 的文件，其中包含以下内容：

package(
    default_visibility = ["//visibility:public"],
    features = [
        "-layering_check",
        "-parse_headers",
    ],
)

licenses(["notice"])  # Apache 2, BSD, MIT

cc_library(
    name = "sentencepiece_processor_ops",
    srcs = [
        "sentencepiece/tensorflow/sentencepiece_processor_ops.cc"
    ],
    hdrs = [
        "sentencepiece/src/sentencepiece_processor.h"
    ],
    strip_include_prefix = "sentencepiece/src/",
    alwayslink = 1,
    deps =
        [
            "@org_tensorflow//tensorflow/core:framework",
            "@org_tensorflow//tensorflow/core:lib",
            "@com_google_protobuf//:protobuf_headers",
            "@com_google_protobuf//:protobuf",
            ":sentencepiece"
        ]
)

cc_library(
    name = "sentencepiece",
    srcs = [
        "sentencepiece/build/src/libsentencepiece.a",
        "sentencepiece/build/src/libsentencepiece_train.a"
    ],
    hdrs = glob(
        ["sentencepiece/src/*.h"]
    ),
    deps = [
        "@com_google_protobuf//:protobuf_headers",
        "@com_google_protobuf//:protobuf",
    ],
    strip_include_prefix = "sentencepiece/src/"
)

与您的Dockerfile 位于同一目录中。即

my-docker-builds
├── BUILD
└── sentencepiece.Dockerfile

这一切都可以用：

$ docker build \
    -t tensorflow-serving-with-sentencepiece:local \
    -f sentencepiece.Dockerfile .

然后等待大约 8 小时 :)

希望这会有所帮助。

编辑： 此外，如果您时间紧迫（而不是金钱），我会在 aws 上启动一台 96 核机器并构建它，它会在大约 10 分钟内完成。
