I am trying to save contents of physiobank Normal Sinus Rhythm RR Interval Database into a numpy array but I keep getting an error:

Traceback (most recent call last):
  File "AverageRRI.py", line 20, in <module>
    averageArray = np.fromfile(file,dtype=float)
FileNotFoundError: [Errno 2] No such file or directory: 'nsr001.ecg'

but the file does exist in the directory.

Thanks so much!

What I have tried:

Python

import os
import numpy as np

for root, dirs, files in os.walk('normal-sinus-rhythm-rr-interval-database-1.0.0'):
    for file in files:
        if file.endswith(".ecg"):
            print(os.path.exists('normal-sinus-rhythm-rr-interval-database-1.0.0/nsr001.ecg'))
            print(file)
            averageArray = np.fromfile(file,dtype=float)
            print(averageArray)

When I add the pathname like:

Python

averageArray = np.fromfile('normal-sinus-rhythm-rr-interval-database-1.0.0/nsr001.ecg',dtype=float)
            print(averageArray)

It works.

Set the absolute path and check again

So you've solved your own question.

If you don't include the path, your code will try to find the file in the current working directory. The file does not exist in the current working directory, so you get an error.
