这里应当注意的点在于,train_dataset = paddle.vision.datasets.MNIST(mode='train'),这句代码,当你目录C:\Users\用户名\.cache\paddle\dataset\mnist下没有对应的数据集时,它会主动下载,但是在python中进行下载,几乎时很费时费力的,所以我建议直接下载数据集在目录下较为方便。

A trained model predicts outcomes based on new input conditions that aren't in the original data set. Some of the typical steps for building and deploying a deep learning application are data consolidation, data cleansing, model building, training, validation, and deployment. Example Python code ...
Conv2D:This convolution layer can be thought of as matrix multiplication using the kernel size matrix in our example (3,3) so if our input size of the image is (28,28) our first Conv2D output would be a matrix of (28–3+1,28–3+1) so (26,26). We also have this process run...
such as learning rate or momentum. The choice for a loss function depends on the task that you have at hand: for example, for a regression problem, you’ll usually use the Mean Squared Error (MSE). As you see in this example, you usedbinary_crossentropyfor the binary classification probl...
