Python: TypeError: an integer is required (got type module)

Question

i have small code to read all image on folder and send them to current API alternately. but this code doesn't work yet, how to solve this problem. thankyou.

import cv2
import os
import json
import requests
import time

vehicle_count = [0]
current_path = os.getcwd() #+ "/"
file = '/image_folder/image' + str(len(vehicle_count)) + ".png"
path = '/home/username/Documents/path/to/image_folder%s' % file
temp_file = current_path + file
result = []

def send_image(source_image):
    cv2.imread(temp_file , source_image)
    vehicle_count.insert(0, 1)
    with open(path, 'rb') as fp:
        response = requests.post(
            'https://url_to_API/',
            files=dict(upload=fp),
            headers={'Authorization': 'Token ' + 'MY_API'})
        result.append(response.json())
        print(json.dumps(result, indent=2));

        with open('data.json', 'w') as outfile:
            json.dump(result, outfile)
    os.remove("%s" %temp_file)

and this is error traceback:

Answer 1

The problem is here: cv2.imread(temp_file, source_image) , you're passing two arguments to the imread() function where only one is needed. Try: cv2.imread(temp_file) given that temp_file is the correct path to the image file you want to load.

Note: the second argument that you can pass to the imread(path, flag) function is flag which specifies the way in which image should be read. It's default value is cv2.IMREAD_COLOR
