使用 CLI v1 创建和管理 Azure 机器学习计算实例

适用于：Python SDK azureml v1

import datetime
import time

from azureml.core.compute import ComputeTarget, ComputeInstance
from azureml.core.compute_target import ComputeTargetException

# Choose a name for your instance
# Compute instance name should be unique across the azure region
compute_name = "ci{}".format(ws._workspace_id)[:10]

# Verify that instance does not exist already
try:
    instance = ComputeInstance(workspace=ws, name=compute_name)
    print('Found existing instance, use it.')
except ComputeTargetException:
    compute_config = ComputeInstance.provisioning_configuration(
        vm_size='STANDARD_D3_V2',
        ssh_public_access=False,
        # vnet_resourcegroup_name='<my-resource-group>',
        # vnet_name='<my-vnet-name>',
        # subnet_name='default',
        # admin_user_ssh_public_key='<my-sshkey>'
    )
    instance = ComputeInstance.create(ws, compute_name, compute_config)
    instance.wait_for_completion(show_output=True)

• ComputeInstance 类
• ComputeTarget.create
• ComputeInstance.wait_for_completion

适用于：Azure CLI ml 扩展 v1

az ml computetarget create computeinstance  -n instance -s "STANDARD_D3_V2" -v

有关详细信息，请参阅 Az PowerShell 模块 az ml computetarget create computeinstance 参考。

适用于：Python SDK azureml v1

在下例中，计算实例的名称为“instance”。

• 获取状态

  # get_status() gets the latest status of the ComputeInstance target
  instance.get_status()
  

• 停止

  # stop() is used to stop the ComputeInstance
  # Stopping ComputeInstance will stop the billing meter and persist the state on the disk.
  # Available Quota will not be changed with this operation.
  instance.stop(wait_for_completion=True, show_output=True)
  

• 开始

  # start() is used to start the ComputeInstance if it is in stopped state
  instance.start(wait_for_completion=True, show_output=True)
  

• 重启

  # restart() is used to restart the ComputeInstance
  instance.restart(wait_for_completion=True, show_output=True)
  

• Delete

  # delete() is used to delete the ComputeInstance target. Useful if you want to re-use the compute name
  instance.delete(wait_for_completion=True, show_output=True)
  

适用于：Azure CLI ml 扩展 v1

在下例中，计算实例的名称均为“实例”

• 停止

  az ml computetarget stop computeinstance -n instance -v
  

  有关详细信息，请参阅 Az PowerShell 模块 az ml computetarget stop computeinstance。

• 开始

  az ml computetarget start computeinstance -n instance -v
  

  有关详细信息，请参阅 Az PowerShell 模块 az ml computetarget start computeinstance。

• 重启

  az ml computetarget restart computeinstance -n instance -v
  

  有关详细信息，请参阅 Az PowerShell 模块 az ml computetarget restart computeinstance。

• 删除

  az ml computetarget delete -n instance -v
