我已经检查了dl4j示例并执行了 AnimalsClassification 示例，以成功进行测试。
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等于 FCN 。
并将 AnimalsClassification 示例的网络从该链接更改为 UNet
但出现错误。 您能帮我解决这个错误吗？
错误：

*
* 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, ...

它指出了堆栈跟踪中的错误。您需要在图形上调用setInputs。这类似于我们在底部设置输出的方式。 请仔细阅读错误消息。
