PermissionError: [Errno 13] Permission denied: 'D:/DATA/mnist'

Minist

问题1，PermissionError: [Errno 13] Permission denied: 'D:/DATA/mnist'

在jupter notebook 用Keras操作的https://elitedatascience.com/keras-tutorial-deep-learning-in-python#step-4的

其中读入数据部分搞了小半天，太烦人，最后用以下方法解决

问题2，ValueError: Negative dimension size caused by subtracting 3 from 1 for 'conv2d_2/convolution' (op: 'Conv2D') with input shapes: [?,1,28,28], [3,3,28,32].
