I am getting this about remove_duplicate_image HOT 1 OPEN

import hashlib
from imageio import imread
import matplotlib.pyplot as plt
import matplotlib.gridspec as gridspec
%matplotlib inline

from tqdm import tqdm
import numpy as np
from glob import glob

def file_hash(filepath):
    with open(filepath, 'rb') as f:
        return md5(f.read()).hexdigest()

file_list = glob("directory_of_the_images")

import hashlib, os
duplicates = []
hash_keys = dict()

for index, filename in  tqdm(enumerate(file_list)):  #listdir('.') = current directory
    if os.path.isfile(filename):
        with open(filename, 'rb') as f:
            filehash = hashlib.md5(f.read()).hexdigest()
        if filehash not in hash_keys: 
            hash_keys[filehash] = index
        else:
            duplicates.append((index,hash_keys[filehash]))
