注意:找到了一个临时解决方案:打开camera.py
,使用pass
并在函数_view_plane_normal_changed
中注释内容,然后重新编译它。
我正在使用python(x,y)2.7.5.1
。当我使用像mayavi这样的tvtk的一些软件包时,会引发一个AttributeError:SetViewPlaneNormal.
我知道这是因为vtk已弃用此方法。
有谁知道如何解决它?
vtk
的版本为5.10.1-3.
完整的引用包含一些像这样的块:
ERROR:traits:Exception occurred in traits notification handler for object: vtkOpenGLCamera (06F89078)

我面临同样的问题。任何mayavi代码都会导致AttributeError:SetViewPlaneNormal
错误。
我的平台是Win 7 Pro x64,包含Python 2.7.5,VTK 5.10.1,Mayavi 4.3.0。
请注意,即使官方的python示例也会导致错误,但即使在控制台中不断打印错误,图形也会正确显示。

每次渲染都会打印多次上面的堆栈跟踪。如果我们移动相机导致FPS大幅下降,那就继续发生。
导致此错误的最简单代码示例:
from mayavi import mlab
mlab.points3d([1], [1], [1])

我也遇到过使用python(x,y)(2.7.5.2)的问题,但是在Anaconda(1.8.0)发行版下,代码运行正常。
# code comes from mayavi docs shipped with python(x,y) 2.7.5.2
# Create the data.
from numpy import pi, sin, cos, mgrid
dphi, dtheta = pi/250.0, pi/250.0
[phi,theta] = mgrid[0:pi+dphi*1.5:dphi,0:2*pi+dtheta*1.5:dtheta]
m0 = 4; m1 = 3; m2 = 2; m3 = 3; m4 = 6; m5 = 2; m6 = 6; m7 = 4;
r = sin(m0*phi)**m1 + cos(m2*phi)**m3 + sin(m4*theta)**m5 + cos(m6*theta)**m7
x = r*sin(phi)*cos(theta)
y = r*cos(phi)
z = r*sin(phi)*sin(theta)
# View it.
from mayavi import mlab
s = mlab.mesh(x, y, z)
mlab.show()
