error: Error -3 while decompressing data: invalid distance too far back

Question

While I am trying to load the .mat file in Python, I am facing the following error:

    error                                     Traceback (most recent call last)

      2     print('Inside Main')
----> 3     mat = loadmat("/content/01_01_c0001_info.mat")
      4     print("File Read........")

error: Error -3 while decompressing data: invalid distance too far back

As we can see the error is occurring in the loadmat function.

The code example is given below:

import numpy as np
from scipy.io import loadmat

if __name__ == '__main__':
    print('Inside Main')
    mat = loadmat("/content/01_01_c0001_info.mat")
    print("File Read........")

File was corrupted. Downloaded it again. It is fixed now. Thank you
