我正在导入 maya.standalone，对其进行初始化，然后将 pymel.core 作为 pmc 导入到我的 Maya Python 解释器中，该解释器在 powershell 中运行。在这一点上，我收到了很多警告。在我调用:xform, shape = pmc.polysphere() 之后，我收到警告:name 'xform' is not defined
这是 pymel 导入的输出

我正在阅读 Practical Maya Programming 这本书，这是书中的文字:
Now we will start digging into Maya and PyMEL. Let's begin by initializing Maya in the mayapy interpreter so we can use more than just standard Python functionality. We do this by calling maya.standalone.initialize, as shown in the following code:
>>> import maya.standalone
>>> maya.standalone.initialize()
>>> import pymel.core as pmc
>>> xform, shape = pmc.polySphere()
The import of pymel.core will implicitly call maya.standalone.initialize automatically, but I do it explicitly here so it's clear what's going on. In the future, you can generally skip the call to maya.standalone.initialize and just import pymel.core.
There is a lot we can discover about these PyMEL objects, which represent Maya nodes, using basic Python. For example, to see the type of either of our objects, we can use the built-in type function (we will dig much deeper into types later in this chapter).
谁能解释我在解释器中遇到的错误并提供解决方案？
最佳答案
(这不是一个完整的答案，但我是菜鸟，所以我不能发表评论。)
一堆警告，看起来像
xgmNurbsPatch [u'containerBase', u'entity', u'dagNode', u'shape', u'geometryShape', u'deformableShape', u'controlPoint', u'surfaceShape', u'THsurfaceShape', u'xgmPatch', u'containerBase', u'entity', u'dagNode', u'shape', u'geometryShape', u'deformableShape', u'controlPoint', u'surfaceShape', u'THsurfaceShape', u'xgmNurbsPatch']
# Warning: pymel.internal.apicache : lineage for node xgmNurbsPatch is cyclical: [u'containerBase', u'entity', u'dagNode', u'shape', u'geometryShape', u'deformableShape', u'controlPoint', u'surfaceShape', u'THsurfaceShape', u'xgmPatch', u'containerBase', u'entity', u'dagNode', u'shape', u'geometryShape', u'deformableShape', u'controlPoint', u'surfaceShape', u'THsurfaceShape', u'xgmNurbsPatch'] #
(我认为)是 Maya 2016 的问题，可能不是您需要担心的任何问题。
我在脚本编辑器中工作，而不是使用 maya.standalone。当我将 Pymel 导入 Maya 2016 时，我收到了 6 个针对各种“xgm”类的警告，与您一样。在以前的 Maya 版本中没有发生这种情况。
至于错误，mtoa/Arnold和xgen都是插件(而且你所有的错误似乎都与插件加载有关)。也许你可以禁用它们？抱歉，我没有在主 Maya 应用程序之外使用 Maya Python 解释器。
编辑:我在此处看到其他人(或者您？)在使用 XGen、Arnold 和 Maya 2016 时遇到类似错误: http://forums.cgsociety.org/archive/index.php?t-1287693.html
