使用visa数据集训练模型，测试效果不理想，与官方已训练模型测试效果相差甚远

Hello author, I tested the Visa dataset using a model that has been trained in engineering and the results were good. However, when I used the Visa dataset, created a meta.json file, and trained for 15 epochs, the testing results were very poor. What is the reason for this?

Maybe the epochs are too small?

Similarly, when I train the replicated model myself and test it on the VISA dataset, the results are not as good as those of the author, with a difference of about 1 to 2 percentage points
