我已经检查了 dl4j 示例并执行了AnimalsClassification示例以成功测试。
我必须训练、评估和预测（使用）像UNet这样的语义分割算法，因为输入图像的大小不同，因此需要FCN。
并将AnimalsClassification示例的网络从此链接更改为UNet
但得到错误。你能帮我解决这个错误吗？
错误：

* - Tiny ImageNet Classification with CNN: http://cs231n.stanford.edu/reports/2015/pdfs/leonyao_final.pdf
*
* CHALLENGE: Current setup gets low score results. Can you improve the scores? Some approaches:
* - Add additional images to the dataset
* - Apply more transforms to dataset
* - Increase epochs
* - Try different model configurations
* - Tune by adjusting learning rate, updaters, activation & loss functions, regularization, ...
