使用 docker 服务多个 tensorflow 模型

Question

看到this github 问题和this stackoverflow 帖子，我希望这能简单地工作。

似乎传入环境变量MODEL_CONFIG_FILE 没有任何影响。我正在通过docker-compose 运行它，但我使用docker-run 遇到了同样的问题。

错误：

Dockerfile

FROM tensorflow/serving:nightly

COPY ./models/first/ /models/first
COPY ./models/second/ /models/second

COPY ./config.conf /config/config.conf

ENV MODEL_CONFIG_FILE=/config/config.conf

撰写文件

version: '3'

services:
  serving:
    build: .
    image: testing-models
    container_name: tf

配置文件

model_config_list: {
  config: {
    name:  "first",
    base_path:  "/models/first",
    model_platform: "tensorflow",
    model_version_policy: {
        all: {}
    }
  },
  config: {
    name:  "second",
    base_path:  "/models/second",
    model_platform: "tensorflow",
    model_version_policy: {
        all: {}
    }
  }
}

错误是因为服务找不到您的模型。

E tensorflow_serving/sources/storage_path/file_system_storage_path_source.cc:369] FileSystemStoragePathSource encountered a file-system access error: Could not find base path /models/model for servable model

您的 docker compose 文件没有在容器中挂载您的模型文件。所以服务找不到你的模型。 我建议设置三个配置文件。

1 docker-compose.yml

2 .env

3 个models.config

docker-compose.yml:

将模型文件从主机挂载到容器。我认为你可以这样做：

 version: "3"
  services:
        sv:
                image: tensorflow/serving:latest
                restart: unless-stopped
                ports:
                        - 8500:8500
                        - 8501:8501
                volumes:
                        - ${MODEL1_PATH}:/models/${MODEL1_NAME}
                        - ${MODEL2_PATH}:/models/${MODEL2_NAME}
                        - /home/deploy/dcp-file/tf_serving/models.config:/models/models.config
                command: --model_config_file=/models/models.config

.env: docker-compose.yml 从这个文件加载信息。

MODEL1_PATH=/home/notebooks/water_model
MODEL1_NAME=water_model
MODEL2_PATH=/home/notebooks/ice_model
MODEL2_NAME=ice_model

models.config：

model_config_list: {
  config {
    name:  "water_model",
    base_path:  "/models/water_model",
    model_platform: "tensorflow",
    model_version_policy: {
        versions: 1588723537
        versions: 1588734567
    }
  },
  config {
    name:  "ice_model",
    base_path:  "/models/ice_model",
    model_platform: "tensorflow",
    model_version_policy: {
        versions: 1588799999
        versions: 1588788888
    }
  }
}

Answer 2

我在 Windows 上遇到了 git bash 的 this 双斜杠问题。

因此，我将@KrisR89 提到的论点通过command 传递给docker-compose。

新的docker-compose 看起来像这样并与提供的dockerfile 一起使用：

version: '3'

services:
  serving:
    build: .
    image: testing-models
    container_name: tf
    command: --model_config_file=/config/config.conf

Answer 3

没有名为“MODEL_CONFIG_FILE”的 docker 环境变量（这是一个 tensorflow/serving 变量，请参阅 docker image link），因此 docker 镜像将仅使用默认的 docker 环境变量（“MODEL_NAME=model”和“MODEL_BASE_PATH =/models")，并在 docker 镜像启动时运行模型“/models/model”。 “config.conf”应该用作“tensorflow/serving”启动时的输入。 尝试运行这样的东西：

docker run -p 8500:8500 8501:8501 \
  --mount type=bind,source=/path/to/models/first/,target=/models/first \
  --mount type=bind,source=/path/to/models/second/,target=/models/second \
  --mount type=bind,source=/path/to/config/config.conf,target=/config/config.conf\
  -t tensorflow/serving --model_config_file=/config/config.conf
