Question

我已经很好地遵循了here概述的文档。

我已经通过以下方式设置了我的azure机器学习环境：

  const rotatePoint = (pivotPoint, point, angle) => {
    const { x: px, y: py } = pivotPoint;
    const { x, y } = point;

    var radians = (Math.PI / 180) * angle,
      cos = Math.cos(radians),
      sin = Math.sin(radians),
      nx = cos * (x - px) + sin * (y - py) + px,
      ny = cos * (y - py) - sin * (x - px) + py;

    return { x: nx, y: ny };
  };

我为推理配置了一个score.py文件（与我遇到的问题无关）...

然后我设置推理配置

from azureml.core import Workspace

# Connect to the workspace
ws = Workspace.from_config()

from azureml.core import Environment
from azureml.core import ContainerRegistry

myenv = Environment(name = "myenv")

myenv.inferencing_stack_version = "latest"  # This will install the inference specific apt packages.

# Docker
myenv.docker.enabled = True
myenv.docker.base_image_registry.address = "myazureregistry.azurecr.io"
myenv.docker.base_image_registry.username = "myusername"
myenv.docker.base_image_registry.password = "mypassword"
myenv.docker.base_image = "4fb3..." 
myenv.docker.arguments = None

# Environment variable (I need python to look at folders 
myenv.environment_variables = {"PYTHONPATH":"/root"}

# python
myenv.python.user_managed_dependencies = True
myenv.python.interpreter_path = "/opt/miniconda/envs/myenv/bin/python" 

from azureml.core.conda_dependencies import CondaDependencies
conda_dep = CondaDependencies()
conda_dep.add_pip_package("azureml-defaults")
myenv.python.conda_dependencies=conda_dep

myenv.register(workspace=ws) # works!

我设置了我的计算集群：

from azureml.core.model import InferenceConfig
inference_config = InferenceConfig(entry_script="score.py", environment=myenv)

一切都成功了；然后我尝试部署模型以进行推断：

from azureml.core.compute import ComputeTarget, AksCompute
from azureml.exceptions import ComputeTargetException

# Choose a name for your cluster
aks_name = "theclustername" 

# Check to see if the cluster already exists
try:
    aks_target = ComputeTarget(workspace=ws, name=aks_name)
    print('Found existing compute target')
except ComputeTargetException:
    print('Creating a new compute target...')
    prov_config = AksCompute.provisioning_configuration(vm_size="Standard_NC6_Promo")

    aks_target = ComputeTarget.create(workspace=ws, name=aks_name, provisioning_configuration=prov_config)

    aks_target.wait_for_completion(show_output=True)

from azureml.core.webservice import AksWebservice

# Example
gpu_aks_config = AksWebservice.deploy_configuration(autoscale_enabled=False,
                                                    num_replicas=3,
                                                    cpu_cores=4,
                                                    memory_gb=10)

它并没有说它找不到环境。更具体地说，我的环境版本是 11版，但它一直在尝试查找版本号比当前环境高1（即 12版）的环境。：

from azureml.core.model import Model

model = Model(ws, name="thenameofmymodel")

# Name of the web service that is deployed
aks_service_name = 'tryingtodeply'

# Deploy the model
aks_service = Model.deploy(ws,
                           aks_service_name,
                           models=[model],
                           inference_config=inference_config,
                           deployment_config=gpu_aks_config,
                           deployment_target=aks_target,
                           overwrite=True)

aks_service.wait_for_deployment(show_output=True)
print(aks_service.state)

我尝试手动编辑环境JSON以匹配Azureml试图获取的版本，但是没有任何效果。有人可以看到这段代码有什么问题吗？

更新

更改环境名称（例如FailedERROR - Service deployment polling reached non-successful terminal state, current service state: Failed Operation ID: 0f03a025-3407-4dc1-9922-a53cc27267d4 More information can be found here: Error: { "code": "BadRequest", "statusCode": 400, "message": "The request is invalid", "details": [ { "code": "EnvironmentDetailsFetchFailedUserError", "message": "Failed to fetch details for Environment with Name: myenv Version: 12." } ] }）并将其传递给my_inference_env似乎是正确的做法。但是，错误现在更改为以下

InferenceConfig

解决方案

以下关于蓝色天蓝色ML环境的使用，实际上是正确的。但是，我遇到的最后一个错误是因为我使用摘要值（sha）而不是图像名称和标记（例如Running.......... Failed ERROR - Service deployment polling reached non-successful terminal state, current service state: Failed Operation ID: f0dfc13b-6fb6-494b-91a7-de42b9384692 More information can be found here: https://some_long_http_address_that_leads_to_nothing Error: { "code": "DeploymentFailed", "statusCode": 404, "message": "Deployment not found" }）来设置容器图像。请注意第一段中的代码行：

imagename:tag

我引用了摘要值，但应将其更改为

myenv.docker.base_image = "4fb3..."

一旦进行了更改，部署就成功了！：）

Answer 1

花了我一段时间的一个概念是注册和使用Azure ML Environment的分歧。如果您已经注册了环境myenv，并且您的环境的详细信息都没有更改，则无需向myenv.register()重新注册它。您可以像这样简单地使用Environment.get()获取已经注册的环境：

myenv = Environment.get(ws, name='myenv', version=11)

我的建议是给您的环境起一个新的名称：例如"model_scoring_env"。将其注册一次，然后将其传递到InferenceConfig。

Azure-ML部署看不到AzureML环境（版本号错误）
