from scipy import signal

 def get_sig_from_txt(directory_path, filename):
    with open(directory_path + '\\' + filename) as f:
       content = f.readlines()
       content = [int(x.strip()) for x in content]
       return np.array(content)


for filename in dirr:
    signal = get_sig_from_txt(path, filename)
    idx_peak = signal.find_peaks_cwt(signal, np.arange(1, 16))

我收到错误：AttributeError：'numpy.ndarray'对象没有属性'find_peaks_cwt'进程。我该怎么办？

Answer 1

您已经隐藏了signal变量，该变量引用了scipy.signal模块。

只需将函数调用的结果分配给另一个名称：

for filename in dirr:
    sig = get_sig_from_txt(path, filename)
    idx_peak = signal.find_peaks_cwt(sig, np.arange(1, 16))

AttributeError：“ numpy.ndarray”对象没有属性“ find_peaks_cwt”进程
