python - 在Azure Kubernetes服务中部署时导入cv2错误-python

Question

我已经阅读过有关天蓝色应用程序服务的类似问题，但仍然找不到答案。我试图在azure kubernetes服务中部署模型，但是在导入cv2时遇到错误(这对我很重要)。
Opencv-python包含在我的环境.yaml文件中:

name: project_environment
dependencies:
  # The python interpreter version.
  # Currently Azure ML only supports 3.5.2 and later.
- python=3.6.2

- pip:
  # You must list azureml-defaults as a pip dependency
  - azureml-defaults>=1.0.45
  - Cython
  - matplotlib>=3.2.2
  - numpy>=1.18.5
  - opencv-python>=4.1.2
  - pillow
  - PyYAML>=5.3
  - scipy>=1.4.1
  - torch>=1.6.0
  - torchvision>=0.7.0
  - tqdm>=4.41.0
channels:
- conda-forge

我正在按以下方式部署:

aks_service = Model.deploy(ws,
                       models=[model],
                       inference_config=inference_config,
                       deployment_config=gpu_aks_config,
                       deployment_target=aks_target,
                       name=aks_service_name)

我得到这个错误:

您可以访问要安装的节点的终端吗？
如果是，请执行以下步骤:
