这是示例代码:
from exampleshelper import dataPath, outputPath
from imagine import modeler
m=modeler.Model()
ri = m.RasterInput(dataPath + "C:/Users/owrasa/PycharmProjects/den/data/lanier.img")
bandSelect = m.BandSelection(ri, "1:4")
sumBands = m.StackTotal(bandSelect)
ro = m.RasterOutput(sumBands, outputPath + "summing-image-layers.img")
m.Execute()
这是整个错误消息:

我想添加一个选项，用户只需使用类似于 Paint 上的笔小部件的鼠标即可绘制任何内容。我尝试了很多东西，我不知道怎么做。我怎么能让海龟用鼠标在画布上画任何东西（比如 Paint 上的笔小部件）
