Question

请帮忙解决这个错误。这是我的代码：

import numpy as np 
import pandas as pd 
from subprocess import check_output
print(check_output(["ls", "/home/mahmood/apnea-ecg"]).decode("utf8"))
import os
os.listdir("/home/mahmood/apnea-ecg")
import wfdb
import numpy as np
import matplotlib.pyplot as plt
recordname = "/home/mahmood/apnea-ecg/a04"
record = wfdb.rdsamp(recordname)
record.p_signals

Answer 1

来自wfdb.rdsamp源代码：

Returns ------- signals : numpy array A 2d numpy array storing the physical signals from the record. fields : dict A dictionary containing several key attributes of the read record: - fs: The sampling frequency of the record - units: The units for each channel - sig_name: The signal name for each channel - comments: Any comments written in the header

因此，您将获得一个由2个元素，信号和场组成的元组。我会写：

p_signals, _ = wfdb.rdsamp(recordname)

AttributeError：“元组”对象没有属性“ p_signals”
