請幫忙，我試圖用Tensorflow下載MNIST數據集時遇到以下錯誤。在Mac OS上加載tensorflow中mnist的問題

你會想以顯示您的代碼，並使用代碼塊格式化您的文章。 – Tchotchke

我建議你安裝TensorFlow as eparate virtualenv。

這裏按照下列步驟：Installing TensorFlow with virtualenv

And always remember to activate the virtualenv environment each time you use TensorFlow in a new shell by running:
$ source ~/<target_directory>/bin/activate

我在'virtualenv'運行，我得到這個太： ' >>> MNIST = input_data.read_data_sets（「MNIST_data /」，one_hot = TRUE）回溯（最近最後一次通話）： ... ssl.SSLError：[SSL：CERTIFICATE_VERIFY_FAILED]證書驗證失敗（_ssl.c：748） ' – aec

我有同樣的問題，和下面的命令（如https://github.com/tensorflow/tensorflow/issues/10779所示）幫助：
