I am having problem in unpickling a .pkl file and editing it. I tried the following code but it shows error. How could I proceed?

import pickle
import numpy as np

with open('speech_emotion_data.pkl', 'rb') as pickle_file:
    new_data = pickle.load(pickle_file)

it shows error as:

UnpicklingError: invalid load key, '\x1f'.

I was having the same problem, it seems that Pickle files have some troubles when compressed. A temporal solution I found here, adding the following:

gzip or xz as parameters to pd.read_pickle function, or, as in your case, using gzip.open

import gzip
with gzip.open('speech_emotion_data.pkl', 'rb') as pickle_file:
