How do i read in selective image files from a folder, where the search criteria is in a PandaFrame frame? Through cv2 in Python

问题

from PIL import Image 

import cv2
import matplotlib.pyplot as plt
import pandas as pd
import os

The following is the filtering out the pandaframe

#######################################################
m = 3000
Metadata = pd.read_csv('ISIC_2019_Training_GroundTruth.csv')

MelanomaData = Metadata.filter(["image" ,"MEL"])
MelanomaData = MelanomaData[MelanomaData.MEL == 1] 
MelanomaData = MelanomaData[:-m]

When i tried to read in the image files i get NonType in my variable explorer view

ImageList = []
ResizingImages = []
image_name_list  = MelanomaData['image'].tolist()
path_string = 'H:/My Documents/FYP/Skin Detection/ISIC_2019_Training_Input/'

datapath = os.path.join(path_string, '.jpg')

for files in datapath:    
    for image_name in image_name_list:
        img = cv2.imread(image_name)
        ImageList.append(img)

The search criteria is found in the image column

    image                                MEL

2   ISIC_0000002                         1.0

4   ISIC_0000004                         1.0

12  ISIC_0000013                         1.0

21  ISIC_0000022_downsampled             1.0

This is the CSV file screen shot but, i only need the image and MEL columns, which is what i extracted, and displayed in the first section where i extracted and filtered that column
