Ausnahme: URL-Abruffehler beim Laden von Daten ⇐ Python

[Anonymous]

Ich versuche, meinen Computer für die Ausführung von Tensorflow 2 einzurichten. Ich habe Tensorflow noch nie verwendet und habe gerade Python 3.7 heruntergeladen. Ich bin mir nicht sicher, ob dies ein Problem mit meiner Maschine ist oder nicht. Ich habe die Installationsanweisungen auf der Website von TensorFlow befolgt. Ich habe die Installationsanweisungen befolgt und alles schien zu funktionieren.

MacOS 10.15.3

Python 3.7

Tensorflow 2

Ich habe ein kleines Programm erstellt, nur um die Dinge auszuprobieren. Das habe ich:

Code: Select all

import io
import matplotlib.pyplot as plt
import tensorflow as tf
from tensorflow import keras
import numpy as np

data = keras.datasets.fashion_mnist

(train_images, train_labels), (test_images, test_labels) = data.load_data()

Wenn ich data.load_data() ausführe, erhalte ich diese Fehlermeldung:

Code: Select all

Auch hier verwende ich Tensorflow und Keras zum ersten Mal, aber es scheint ein Verbindungsproblem mit dem API-Dienst von Google zu sein.

Jede Hilfe wäre sehr dankbar, da ich nichts finden kann.
