我无法运行我编写的用于开始理解 Deeplearning4j 的简单程序。
我尝试了此链接中的代码: Deep Learning In Java Using Deeplearning4J
不幸的是，它对我不起作用。事实上我有这个错误:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". SLF4J: Defaulting to no-operation (NOP) logger implementation SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

如有任何建议，我将不胜感激。提前致谢
最佳答案
除了上面的评论:您需要一个 nd4j 后端。请查看错误消息。相关文档就在该链接中。通常您需要 nd4j-native-platform 和最新版本。对于最新版本的东西，请使用我们的示例存储库:https://github.com/deeplearning4j/dl4j-examples
