Question

我正在尝试运行以下 link 中的代码“https://github.com/habom2310/Heart-rate-measurement-using-camera”

但是我得到如下导入错误：

ImportError: cannot import name 'registerParameterItemType' from 'pyqtgraph.parametertree.Parameter' (C:\Users\ialam\anaconda3\lib\site-packages\pyqtgraph\parametertree\Parameter.py)

谁能帮我解决这个问题？
