error while loading .mat file in google colab

I have a .mat file which i need to open/load in google colab. the file size is 590MB. I have uploaded file on google colab from my local drive. Then I have used different codes like following,

from scipy.io import loadmat

data=loadmat('Perfect_H_40000.mat')

another one is,

from os.path import dirname, join as pjoin

import scipy.io as sio

data_dir = pjoin(dirname(sio.file), 'matlab', 'tests', 'data')

mat_fname = pjoin(data_dir, 'Perfect_H_40000.mat')

mat_contents = sio.loadmat(mat_fname)

there is another,

import h5py

f = h5py.File('Perfect_H_40000.mat')

but all the time I failed to load this .mat file. please suggest some suitable method. Thankyou
