[4940] Failed to execute script high
0.7876  WARNING         We strongly recommend you activate the PTB sound engine in PsychoPy prefs as the preferred audio engine. Its timing is vastly superior. Your prefs are currently set to use ['sounddevice', 'pyo', 'pygame'] (in that order).

检查你是否使用了图片文档字体等资源，如果有，需要把这些相关资源放在exe同目录下。
若仍然无法解决，
建议重新安装所依赖的库，Matplotlib3或更老版本

直接屏蔽该警告即可
