我正在尝试使用 Pyautogui 为名为“Graal Online Classic”的 MMO 创建一个机器人。它会读取向其发送消息的玩家的“PM”（个人消息），然后回复适当的响应。它还会截取玩家姓名的屏幕截图，将其存储在字典中（还存储该特定玩家在机器人响应层次结构中的位置），并使用它来确定玩家之前是否曾向他们发送过消息。

print(image)

pyautogui.click(image)

main()
它会产生以下错误。

我对列表和字典没有太多经验，所以我不确定如何处理这个问题。我查看了类似的线程，并出现错误“TypeError：不可散列类型：”，但我并不真正理解这些响应。任何帮助将不胜感激，谢谢。
为了将项目添加到字典中，它必须是可散列的。在大多数情况下，这意味着它必须是不可变的。您不能直接对
PIL.Image.Image()bytes# Store the image
name_image = pyautogui.screenshot('name_test.png', region = name_coords)
name_image_asbytes = name_image.tobytes()
players[name_image_asbytes] = None
# Retrieve data associated with the image
# In this case, I am using my_img as the image I want to get associated data from
data = players[my_img.tobytes()]
# Create image from bytes (in case you ever need to later on)
# You would also need to install the PIL library for this, but I suspect it is already installed because pyautogui needs PIL
