错误：在为 azure ML ACI 部署创建 docker 映像时无法卸载“ruamel-yaml”

Question

我正在尝试在 azure ACI 中部署机器学习模型，但在创建 docker 映像时出现以下错误

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.

**谁能帮帮我吗 **

Answer 1

这是自 pip 版本 10 以来的一个问题（关于 pip repo 的相关讨论）。该线程详细介绍了一些解决方案：

手动删除文件site-packages。就我而言，删除ruamel.yaml命令是rm -rf /path/to/anaconda3/lib/python3.7/site-packages/ruamel*

您还可以将 pip 降级到版本 <10，使用该--disable-pip-version-check选项重新安装 ruamel ，然后使用pip install --upgrade pip.

更新：这是一个删除 ruamel 包的 1-liner：

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

分解一下： $(...) 中的所有内容都是用于获取全局站点包目录（source）的单行代码。该rm -rf递归删除ruamel包目录。该/ruamel*后缀瞄准ruamel包。

我在其他包 ( boto, gmpy2, pycosat) 中遇到了同样的问题，解决方案是相同的，只是替换了后缀。

也许使用“pip install --ignore-installed [package]”
