导入 vtk ModuleNotFoundError：没有名为“vtkCommonCorePython”的模块

Question

好的，有多个类似的错误并且没有确定的解决方案： 系统：windows 10、conda 4.10.3、python 3.7.11

在 cmd 中我激活了 conda 虚拟环境：conda activate tensorflow

我跑了

import vtk

又回来了：

ImportError                               Traceback (most recent call last)

      4     # use relative import for installed modules
----> 5     from .vtkCommonCorePython import *
      6 except ImportError:

ImportError: DLL load failed: The specified module could not be found.

During handling of the above exception, another exception occurred:

ModuleNotFoundError: No module named 'vtkCommonCorePython'

之前在 conda 虚拟环境中我运行 conda install vtk 并且运行良好。

我的路径变量包含：D:\user_data\Program_Files\Anaconda3

我还搜索并找到了以下文件夹：D:\user_data\Program_Files\Anaconda3\pkgs\vtk-8.2.0-py37h1e53df8_200

我还能如何排除故障？

我想强调这个问题。它在 Python 3.7 及更低版本中非常通用。 VTK 根本不加载，出现这个确切的错误。简单做一个虚拟环境，Conda安装VTK，然后尝试导入vtk。
