当代码为 运行 时，Turtle 图形脚本不断崩溃
Turtle graphics script keeps crashing when code is run
我正在创建一个加载图像并将其转换为 1 和零的项目，然后使用 turtle 绘制它。然而，每次我 运行 它告诉我它在第一列完成后停止工作。如果问题出在我的计算机的处理能力上，我想知道是否有办法切换到 GPU 来完成任务。任何帮助将不胜感激。谢谢

这段代码一团糟。您将名为 Maze 的 JPEG 迷宫图像输入二维数组并将其传递给 ShowMaze(Maze) 以表明您已正确读取它。但是 ShowMaze() 全局访问 Maze 并认为它的论点是 ShowMaze(possibleRoutes) 其中 possibleRoutes 从未计算过迷宫？另外：Maze 的 X 和 Y 意义似乎颠倒了；迷宫的行有一层额外的 list 包裹着它们，没有明显的原因；包含死代码；你读的不是 1 和 0，而是四种不同的颜色代码；绘图代码似乎没有希望。
我修改了你的代码，简单地将迷宫读入列表列表，然后使用 stamping 而不是 drawing[=33] 与海龟一起显示它=] 来简化和加速代码：

PIXEL_SIZE = 5

height, width = len(maze), len(maze[0])
screen = Screen()
screen.setup(width * PIXEL_SIZE, height * PIXEL_SIZE)
screen.setworldcoordinates(0, height, width, 0)
turtle = Turtle('square', visible=False)
turtle.shapesize(PIXEL_SIZE / CURSOR_SIZE)
turtle.penup()
screen.tracer(False)
for y in range(height):
for x in range(width):
color = maze[y][x]
if color in COLORS:
turtle.fillcolor(COLORS[color])

turtle.fillcolor("orange") # error color
turtle.stamp()
turtle.forward(1)
turtle.goto(0, turtle.ycor() + 1)
screen.tracer(True)
screen.mainloop()
