我如何在 google colab 中读取 phton 中的 .bdf 文件

编程问答 2022-04-28

问题描述

我正在处理 deap 数据集，我想使用 python 在 google colab 中打开和查看 .bdf 文件的原始数据文件。但是当我把这段代码

import pyedflib
import numpy as np
import matplotlib.pyplot as plt

f = pyedflib.EdfReader('/content/drive/MyDrive/s01.bdf')

n = f.signals_in_file

signal_labels = f.getSignalLabels()

sigbufs = np.zeros((n,f.getNSamples()[0]))

fig = plt.figure()

ax = plt.axes()

for i in np.arange(n):

        sigbufs[i,:] = f.readSignal(i)

        ax.plot(f.readSignal(i))

        plt.show()

我收到此错误

OSError                                   Traceback (most recent call last)

      4 import matplotlib.pyplot as plt

----> 5 f = pyedflib.EdfReader('/content/drive/MyDrive/s01.bdf')

      6 n = f.signals_in_file

      7 signal_labels = f.getSignalLabels()
