Failed to attach map when modeling maps in python

I want to explain the BIMBase installation path in D disk because I want to use the map in the BIMBase library. Turn to < a href = "https://blog.csdn.net/weixin_43284694/article/details/116062024?spm=1001.2014.3001.5502" target="_blank"> BIMBase Python The parameterized component library manual just found a way to use python maps

Example code is as follows

# 定义参数化模型
class 长方体(Component):
 # 定义各个参数及其默认值
 def __init__(self):
   Component.__init__(self)
   self['长'] = Attr(1000, obvious = True, combo = [500,1000,2000,3000,4000])
   self['宽'] = Attr(300.0, obvious = True)
   self['高'] = Attr(500, obvious = True)
   self['长方体'] = Attr(None, show = True)
   self.replace()
 @export
  # 模型造型
 def replace(self): 
   # 设置变量，同时调用参数(简化书写过程)
 
   L = self['长']
   W = self['宽']
   H = self['高']
 # 绘制模型
   TestCube = scale(L,W,H) * Cube()
   self['长方体'] = TestCube
   self['长方体'].material('M8')
 
# 输出模型
if __name__ == "__main__":
  mt3 = create_material('M8', mapMode = 5, mapUnit = 0, uvScale = [1,1], 
  wRotation = 0)
 mt3.mapFile = R'C:\Users\PKPM\Pictures\BIMBase 图标.png'
 FinalGeometry = 长方体()
  place(FinalGeometry)

The final result is

I write the
code according to the example method as follows

from pyp3d import *
class 椅子(Component):
    def __init__(self):
        Component.__init__(self)
        # 绘制模型参数

        self['椅子'] = Attr(None,show=True)
        self.replace()
