mono - Sagemaker 上的 pythonnet 无法导入 clr

问题描述

出现此错误，我无法从 SageMaker 导入 clr。什么样的调整使这个成功？

从 Sagemaker 控制台：

source activate python3    
conda install pythonnet

这似乎可以很好地安装 pythonnet 而不会出错。

在python代码中：

import clr

这会产生此错误：

Traceback (most recent call last):

    import clr

环境 ：

类似症状：

尝试导入 clr 时出现 System.DllNotFoundException，尽管引用的程序集存在 #1034：我在正确的目录中确认了 libmono-native.so 库。
