问题描述
我在使用 tensorflow 时遇到问题.它似乎正确安装和导入.然而，当我调用它时，解释器会抛出一连串扩展的异常，下面给出了删节.
I have trouble using tensorflow. It seems to install and import properly. However when I call it, the interpreter throws an extended litany of exceptions with abridgment given below.

先谢谢你！
推荐答案
如果您正在尝试加载 MNIST 数据集，则语法为:tf.keras.datasets.mnist.load_data
If you are trying to load an MNIST datset, the syntax is:tf.keras.datasets.mnist.load_data
例如:tf.keras.datasets.mnist.load_data(path='mnist.npz')
你可以参考这个页面:https://www.tensorflow.org/api_docs/python/tf/keras/datasets/mnist/load_data
