化学信号找到_peaks数组维数

Question

我在查看几百个数据文件，寻找信号的峰值。我有一个numpy数组中的数据，并试图使用scipy中的find_peaks方法。不管怎样，我都会得到：

ValueError: x must have exactly one dimension

代码如下：

#Load electron signal data from file
data = np.loadtxt("C3tsss00001.txt", delimiter=" ", skiprows=5, dtype=float)

time, volts = np.hsplit(data, 2)

voltssmth = savgol_filter(volts, 5, 2, mode='nearest')

print(volts)
print(voltssmth)

#Invert negative detected signals into positive ones
volts = volts * -1
voltssmth = voltssmth * -1


#find peak due to detected electrons
peaks, _ =find_peaks(volts, height = .005)

这是完整的错误回溯 回溯（最近一次呼叫）：

^{pr2}$

值错误：x必须正好有一个维度

以下是给出问题的一小部分数据：
