10 and 49 corresponds to the number of batches which your dataset has been divided into in each epoch. 10 和 49 对应于您的数据集在每个 epoch 中划分的批次数。
For example, in your train dataset, there are totally 10000 images and your batch size is 64, then there will be totally math.ceil(10000/64) = 157 batches possible in each epoch.例如，在您的训练数据集中，总共有 10000 张图像，您的批量大小为 64，那么每个 epoch 总共可能有math.ceil(10000/64) = 157批次。
