#错误：ImportError:没有名为的模块样品.光强度#

Question

这是我的剧本：

import maya.cmds as cmds

def changeLightIntensity(percentage=1.0):
    """
    Changes the intensity of each light the scene by percentage.

    Parameters:
        percentage - Percentage to change each light's intensity. Default value is 1.

    Returns:
        Nothing.
    """
    #The is command is the list command. It is used to list various nodes
    #in the  current scene. You can also use it to list selected nodes.
    lightInScene = cmds.ls(type='light')

    #If there are no lights in the scene, there is no point running this script
    if not lightInScene:
        raise RunTimeError, 'There are no lights in the scene!'

    #Loop through each light
    for light in lightInScene:
        #The getAttr command is used to get attribute values of a node
        currentIntensity = cmds.getAttr('%s.intensity' % light)
        #Calculate a new intensity
        newIntensity = currentIntensity * percentage
        #Change the lights intensity to the new intensity
        cmds.setAttr('%s.intensity' % light, newIntensity)
        #Report to the user what we just did
        print 'Changed the intensity of light %s from %.3f to %.3f' % (light, currentIntensity, newIntensity)


import samples.lightIntensity as lightIntensity
lightIntensity.changelightIntensity(1.2)

我的错误是：

ImportError: No module named samples.lightIntensity

怎么了？我能处理这个吗？解决办法是什么？在

谢谢！在

似乎您正在遵循this教程。您所误解的是，代码示例中的最后两行不应该是脚本的一部分，但它们应该在解释器中运行前面的代码。如果您再看一下教程，您将看到主代码示例上方有一个标题，上面写着光强度.py，而第二个较小的代码示例前面有“以运行此脚本，请在脚本编辑器中键入…

所以，这个：

import samples.lightIntensity as lightIntensity
lightIntensity.changelightIntensity(1.2)

不应该以那种形式出现在你的档案中。在

你可以做两件事。不过，我更希望你能轻松地使用第二个代码。在

1. 将不带最后两行的代码保存为lightIntensity.py，并在pythonshell中（在命令行上启动python，使用IDLE，无论使用什么），在提示符后，键入import lightIntensity导入脚本，并lightIntensity.changelightIntensity(1.2)调用脚本中的函数。

2. 或者，可以修复脚本，使其在不尝试导入自身的情况下运行。为此，请删除import行并将最后一行更改为changelightIntensity(1.2)
