导入语句上的Python缩进错误？

我正在为应用程序Maya编写python脚本。在控制台中，我得到此错误：

# Error: IndentationError: file <maya console> line 2: expected an indented block # 

但这是一个简单的导入语句。我不确定为什么要得到它，它仅发生在“ import neoARLLF”语句上。如果将其取出，它将不再提供。该模块肯定与其余脚本一起位于文件夹中，否则我认为我会收到导入错误。此外，脚本的其余所有部分都正确缩进了，并且我没有混合制表符和空格，它们全部缩进了4个空格。

import maya.cmds as mc
import neoARLLF
import neoARnameConv
reload(neoARnameConv)
reload(neoARLF)

seg = neoARLLF.MidLvlFunc()
nameC = neoARnameConv.NameConv()

def jntSegTest():
    jointRad = mc.joint("joint1", q=True, rad=True)
    jnts = 2
    names = []

    for i in xrange(1, 2, 1):
        name = nameC.curConv("test", "AuxKnee", "right", "joint", "01")
        names.append(name)

    seg.segmentJnt("joint1", "joint2", jnts, "y", jointRad, names)

jntSegTest()

有人知道这段代码是怎么回事吗？我已经搜索了很长时间，发现的所有缩进错误都涉及到将制表符与空格混合，或者在分号（定义，类，循环等）之后无法正确缩进。所以我很茫然。

如果有帮助，请在此提供模块neoARLLF的代码。我认为这段代码中有很多错误，但是我无法测试代码来修复它，直到我可以使import语句在上一个模块中工作
