我正在嘗試使用 matplotlib 從我的檔案夾中列印一堆圖片，但是我不確定如何解決此錯誤。
基本上，我正在嘗試使用模式 ' _ 0 _ ' 或 ' _ 1 _ ' 獲取特定檔案，但它給了我一個錯誤并且不知道如何修復它。
我放了我試圖復制的代碼示例的螢屏截圖，如果您有任何問題，請告訴我。歡迎任何幫助！
import os
import matplotlib.pyplot as plt
from matplotlib.image import imread
#folder = '/content/drive/MyDrive/Colab Notebooks/data/dogs-vs-cats/train/'
plt.figure(figsize=(10,10))
for i in range(10):
plt.subplot(4,5,i 1)
filename = glob.glob(os.path.join(folder,'*_1_*.jpg'))
#for filename in folder:
#filename = glob.glob(folder '*_1_*.jpg')
#filename = glob.glob('/content/drive/MyDrive/Colab Notebooks/train_val'/'*_1_*.jpg')
#filename = folder '*_1_*.jpg'
if not os.path.exists(filename):
#if not os.path.exists(filename):
print ('No such file:' filename)
image = imread(filename)
plt.imshow(image)
for i in range(10):
plt.subplot(4,5,i 11)
plt.subplot(4,5,i 11)
plt.subplot(4,5,i 11)
filename = glob.glob(os.path.join(folder,'*_0_*.jpg'))
#filename = glob.glob('/content/drive/MyDrive/Colab Notebooks/train_val'/'*_0_*.jpg')
#filename = folder ' *_0_*.jpg'
image = imread(filename)
plt.imshow(image)
plt.show()

我要完成的作業：
uj5u.com熱心網友回復：
該glob.glob()函式回傳一個串列，錯誤訊息告訴您
TypeError: stat: path should be string, bytes, os.PathLike or integer, not list
你的回圈應該是這樣的，而不是：
for i in range(10):
plt.subplot(4, 5, i 1)
filelist = glob.glob(os.path.join(folder, '*_1_*.jpg'))
to_process = []
for entry in filelist:
if not os.path.exists(entry):
print ("File {entry} does not exist".format(entry=entry))
continue
else:
to_process.append(entry)
for entry in to_process:
# ... other desired processing
