Numpy ke csv file

halo, saya mau bertanya. Bagaimana cara menulis ke file csv dari hasil output numpy loop ?

import glob

import cv2

from os import listdir

from os.path import isfile, join

import os

import numpy as np

from sklearn.utils.validation import check_array

import csv

import pandas as pd

def find_mode(np_array) :

        vals,counts = np.unique(np_array, return_counts=True)

        index = np.argmax(counts)

        return(vals[index])

folder = ("C:/Users/ROG FLOW/Desktop/Untuk SIDANG TA/Sudah Aman/testbikincsv/folderdatacitra/*.jpg")

for file in glob.glob(folder):

    image = cv2.imread(file)

    rows = image.shape[0]

    cols = image.shape[1]

    middlex = cols/2

    middley = rows/2

    middle = [middlex,middley]

    titikawalx = middlex - 10

    titikawaly = middley - 10

    titikakhirx = middlex + 10

    titikakhiry = middley + 10

    crop = image[int(titikawaly):int(titikakhiry), int(titikawalx):int(titikakhirx)]

    c = cv2.cvtColor(crop, cv2.COLOR_BGR2HSV)

    H,S,V = cv2.split(c)

    Modus_citra = find_mode(H)                # tinggal masukan ke csv

import necessary libraries

import pandas as pd import numpy as np

create a dummy array

arr = np.arange(1,11).reshape(2,5)

display the array

print(arr)

convert array into dataframe

DF = pd.DataFrame(arr)

save the dataframe as a csv file

DF.to_csv("data1.csv")</pre><div><br>Sumber <a href="https://www.geeksforgeeks.org/convert-a-numpy-array-into-a-csv-file/">https://www.geeksforgeeks.org/convert-a-numpy-array-into-a-csv-file/</a></div>
