python 3中的mayavi特征错误

我试图在我的conda环境中将Mayavi与python 3.5结合使用。到目前为止，我从下载了VTK-7.1.0-cp35-cp35m-win_amd64.whl，然后运行

pip安装VTK-7.1.0-cp35-cp35m-win_amd64.whl

。按照中的建议，Mayavi是与pip install Mayavi一起安装的

我试过：

得到了这个错误：

TraitError:SmartVolumeMapper实例的“vector_component”特征必须为0，使用mayavi需要一组兼容的vtk、pyvtk和traits/mayavi库。这通常是通过使用包管理器来实现的。例如，您是否尝试过conda安装-c anaconda mayavi=4.5.0

当您使用conda时，从中获利是有意义的。我当然尝试过，但在我的python 3.5环境中没有成功

conda info mayavi

说mayavi 4.5.0依赖于python 2.7。我在找一个解决办法。
