How can I handle the error "certificate verify failed: certificate has expired" in TensorF-CodePudding

I'm just starting to create an image classification program in Python with TensorFlow using the CIFAR10 dataset, following this tutorial. Here is my code so far:

import tensorflow as tf
from tensorflow.keras import datasets, layers, models
import matplotlib.pyplot as plt
import numpy as np
datasets.cifar10.load_data()

I'm getting an error as follows:

  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,
  File "C:\Users\Admin\AppData\Local\Programs\Python\Python39\lib\http\client.py", line 1257, in request

  File "C:\Users\Admin\AppData\Local\Programs\Python\Python39\lib\http\client.py", line 1303, in _send_request
    self.endheaders(body, encode_chunked=encode_chunked)
  File "C:\Users\Admin\AppData\Local\Programs\Python\Python39\lib\http\client.py", line 1252, in endheaders

    self.do_handshake()

    self._sslobj.do_handshake()
ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: certificate has expired (_ssl.c:1129)

What does this error mean, and what can I do to fix it? I'm a beginner with TensorFlow and haven't been able to find an exact solution for this issue.

CodePudding user response：

Recently had a similar error using python 3.7 and just turned off the verification like this:

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()

Check out this issue for more information. You can of course try to install the missing certificates for your Python version. I can confirm that your code works on Google Colab. So it is definitely due to some missing certificates.
