python - 错误: Cannot uninstall 'ruamel-yaml' while creating docker image for azure ML ACI deployment

Question

我正在尝试在 azure ACI 中部署机器学习模型，但在创建 Docker 镜像时遇到以下错误

Pip subprocess error:
ERROR: Cannot uninstall 'ruamel-yaml'. It is a distutils installed project and thus we cannot 
accurately determine which files belong to it which would lead to only a partial uninstall.

下面是我的 pip 依赖项的 yml 文件

name: project_environment
dependencies:
# The python interpreter version.

# Currently Azure ML only supports 3.5.2 and later.


- pip:
  # Required packages for AzureML execution, history, and data preparation.
  - pandas
  - azureml-defaults
  - azureml-sdk
  - azureml-widgets
  - numpy
  - tensorflow-gpu
  - keras
  - azureml-defaults
  - torch==1.4.0
  - scikit-learn==0.22.2.post1

如果我使用 conda 而不是 pip 那么我会收到以下错误

Step 11/13 : RUN CONDA_ROOT_DIR=$(conda info --root) && if [ -n 
"$AZUREML_CONDA_ENVIRONMENT_PATH" ]; then conda env update -p

Please double check and ensure you dependencies file has
the correct spelling.  You might also try installing the
conda-env-Conda package to see if provides the required
installer.

自 pip 版本 10 ( relevant discussion on the pip repo ) 以来，这是一个问题。该线程详细介绍了一些解决方案:

Manually delete来自site-packages的文件。就我而言，删除 ruamel.yaml命令是 rm -rf /path/to/anaconda3/lib/python3.7/site-packages/ruamel*

You can also将 pip 降级到版本 <10，使用 --disable-pip-version-check 重新安装 ruamel选项，然后使用 pip install --upgrade pip 反转降级.

更新:这是删除 ruamel 包的 1-liner:

rm -rf $(python -c "from distutils.sysconfig import get_python_lib; print(get_python_lib())")/ruamel*

分解: $(...) 中的所有内容都是一行，用于获取全局站点包目录 ( source )。 rm -rf递归删除 ruamel 包目录。 /ruamel*后缀针对 ruamel 包。

我在其他软件包( boto 、 gmpy2 、 pycosat )中遇到了同样的问题，解决方案是相同的，除了替换后缀。
