当我使用mayavi（4.3.1）可视化网格时，它会发出以下警告：
警告：导入的VTK版本（5.1）与使用的版本不匹配 建立TVTK课程（6.3）。这可能会导致问题。 请重建TVTK。
我的系统： MS Windows 7 64位，Anaconda 4.3.1（最新版本），

我搜索了论坛，但大多数答案都认为它是4年前VTK中的一个错误，例如TVTK Error in Mayavi (Python)。我不确定它是否有一个坚定的解决方案。在我的计算机中，确实有另一个版本的VTK（版本＆gt; 6），但它是用C ++编写的，与python和Mayavi没有任何关系。
我运行Maya示例代码时遇到的错误如下（由于我的VTK是5.10（如上所述），警告消息非常混乱，而且版本5.1的位置很奇怪），

答案 0 :(得分：3)
经过3天的艰苦努力，我找到了一个解决方法，我在这里发布了对类似的受害者有所帮助。我强烈建议Mayavi / TVTK的开发人员更加关注这个错误。
这篇文章对我很有帮助，https://github.com/ContinuumIO/anaconda-issues/issues/1510。相同的初始安装，然后更新（我的初始帖子）VTK从5到6，如https://repo.continuum.io/pkgs/free/win-64/中所列。基于python / VTK版本的改变的SetInputConnection / SetInputData接口的内在错误。
