我一直在研究一个项目，我需要调用pyautogui.press（'space'），但是，当调用这个项目时，会有一个明显的滞后。我需要尝试使代码以相当快的速度运行，因为正在使用OpenCV。如果有人知道我怎样才能在pyautogui.press（'space'）被调用时阻止代码放慢速度，那将是惊人的。当恐龙跳跃时，您还可以在视频中看到延迟：https://www.youtube.com/watch?v=vceDabnT3OE。pyautogui.press（）在调用时导致延迟
下面是代码：

sch, scw = smallCactus.shape[:-1]
bch, bcw = bigCactus.shape[:-1]
ph, pw = ptero.shape[:-1]

lastTime = time.time()

pyautogui.keyDown('space')
