如何导入PyMEL core？

我正在导入maya.standalone，对其进行初始化，然后将pymel.core as pmc导入到我在powershell中运行的Maya Python解释器中。在这一点上，我得到了很多警告。当我打电话给：xform, shape = pmc.polysphere()之后，我得到警告：name 'xform' is not defined

这是pymel导入的输出

我正在阅读《实用Maya编程》一书，以下是书中的文本：

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:

^{pr2}$

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).

有人能解释一下我在翻译中遇到的错误并提出解决办法吗？在

由于您使用的是windows，请确保您没有使用Powershell ISE。只需使用标准的Powershell。在

正如@Boon所说，这些错误大多来自插件和一些本可以编写得更好的Maya代码。在

当你专注于学习编程时，你不需要那些插件。可以从交互式Maya会话禁用它们：

  1. 打开Maya。在
  2. 选择Windows->设置/首选项->插件管理器
  3. 关闭所有不在的插件的“加载”和“自动加载” 顶部部分：即Xgen、biflost、Substance、mtoa等
  4. 关闭Maya。在

现在在您的shell中重试：

mayapy
import maya.standalone
maya.standalone.initialize()
import pymel.core as pm

在这一点上，我看到一个关于Y-Up的警告，一些Alembic版本信息，其他什么都没有。没什么好担心的。在

提示是>>>，这是一件好事。现在应该可以输入pymel命令了： 键入（一次一个以查看输出）：

^{pr2}$

编辑

如果您正在使用powershell并设置了一个配置文件，则可以通过将以下行添加到剖面图.ps1公司名称：

function ms { mayapy -i  -c "import maya.standalone;maya.standalone.initialize();import pymel.core as pm;print('maya standalone initialized and pymel.core imported as pm')" }

现在可以打开powershell，输入ms并开始编码。在

（这不是一个完整的答案，但我是个无名小卒，所以不允许发表评论。）

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'] #

是（我认为）玛雅2016的问题，可能不是你需要担心的。在

我在脚本编辑器中工作，而不是使用maya.独立. 当我将Pymel导入到Maya 2016中时，我会收到6条针对各种“xgm”类的警告，与您相同。在早期版本的Maya中没有发生这种情况。在

至于错误，mtoa/Arnold和xgen都是插件（所有的错误似乎都与插件加载有关）。也许你可以让他们瘫痪？抱歉，我没有在主Maya应用程序之外使用Maya Python解释器。在

编辑：我看到别人了（或者你呢？）XGen、Arnold和Maya 2016也存在类似错误： http://forums.cgsociety.org/archive/index.php?t-1287693.html
