按照本教程，我剛剛開始使用 CIFAR10 資料集使用 TensorFlow 在 Python 中創建影像分類程式。到目前為止，這是我的代碼：
import tensorflow as tf
from tensorflow.keras import datasets, layers, models
import matplotlib.pyplot as plt
import numpy as np
datasets.cifar10.load_data()
我收到如下錯誤：
File "C:\Users\Admin\AppData\Local\Programs\Python\Python39\lib\urllib\request.py", line 1346, in do_open
h.request(req.get_method(), req.selector, req.data, headers,

self._sslobj.do_handshake()
ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: certificate has expired (_ssl.c:1129)
這個錯誤是什么意思，我能做些什么來修復它？我是 TensorFlow 的初學者，一直無法找到針對此問題的確切解決方案。
uj5u.com熱心網友回復：
最近在使用python時遇到了類似的錯誤3.7，只是像這樣關閉了驗證：
import tensorflow as tf
from tensorflow.keras import datasets, layers, models
import matplotlib.pyplot as plt
import numpy as np
import ssl
ssl._create_default_https_context = ssl._create_unverified_context
datasets.cifar10.load_data()
查看此問題以獲取更多資訊。您當然可以嘗試為您的 Python 版本安裝缺少的證書。我可以確認您的代碼適用于 Google Colab。所以這肯定是由于缺少一些證書。
