如何讀取DataFrame的資料 - Cupoy

from PIL import Image
from io import BytesIO
import numpy as np
import matplotlib.pyplot as plt

# 請用 df.loc[...] 得到第一筆資料的連結
first_link = df.loc[0:0,1:]
response = requests.get(first_link)
img = Image.open(BytesIO(response.content))

# Convert img to numpy array

plt.imshow(img)
plt.show()
