这个错误提示已经在之前回答中提到了，是由于传递给 `butter_lowpass` 函数的参数类型不正确导致的。可以检查一下 GetRpeak.py 中调用 `butter_lowpass` 函数时，传递的参数格式是否如下所示：

butter_lowpass(cutoff, sample_rate, order=order)

其中，`cutoff` 参数应该为一个浮点数列表，如 `[0.5, 40.0]`，而 `sample_rate` 参数应该为一个整数或浮点数，表示信号的采样率。如果传递的参数格式正确，但依然出现这个错误，可以将 `cutoff` 参数改为一个浮点数，如 `cutoff = 0.5`。
