import io

import zipfile

def makeZip(data_list):

    zip_buffer = io.BytesIO()

    with zipfile.ZipFile(zip_buffer, "a", zipfile.ZIP_DEFLATED, False) as zip_file:

        for file_name, data in data_list:

            zip_file.writestr(file_name, data.getvalue())

    return zip_buffer

data_list = [('1.txt', io.BytesIO(b'111')), ('2.txt', io.BytesIO(b'222'))]

zip_buffer = makeZip(data_list)

with open('./b.zip', 'wb') as f:

    f.write(zip_buffer.getvalue())

Thank you.

Byte 2 opencv Mat

refer to below source code. ^^

import base64
import numpy as np
import cv2

def byte2Mat(data):

    imgdata = base64.b64decode(data)

    nparr = np.frombuffer(imgdata, np.uint8)

    img = cv2.imdecode(nparr, cv2.IMREAD_COLOR)

    print(img.shape)

    

    return img
