Question

我正在尝试遵循“使用Scikit-Learn和Tensorflow进行机器学习动手”和练习请求之一来加载MNIST数据集。我按照下面的代码

    from sklearn.datasets import fetch_openml
    mnist = fetch_openml('MNIST_784', version = 1)

但是我收到以下回溯错误：

Traceback (most recent call last):

  File "<ipython-input-15-a3c5f878b528>", line 1, in <module>
    mnist = fetch_openml('MNIST original', version = 1)

    raise HTTPError(req.full_url, code, msg, hdrs, fp)

HTTPError: Bad Request

以下是我正在使用的sklearn的当前版本：

    print('The scikit-learn version is {}.'.format(sklearn.__version__))
    The scikit-learn version is 0.20.3.

我也在使用Anaconda Navigator，我认为可能是问题所在。我执行了“ conda update scikit-learn”，并假设我的软件包已经过时了，但是事实并非如此。

如果有类似问题的答案，请标记为重复。
