批量运行我的Repast Simphony模型时，出现以下错误消息：
log4j:WARN No appenders could be found for logger (RLFA.society3.run.1.1).
log4j:WARN Please initialize the log4j system properly.
关于log4j http://repast.sourceforge.net/docs/tutorial/SIM/Frequently%20Asked%20Questions.html#FrequentlyAskedQuestions-log4j的答案根本没有帮助，因为我只有在开始批量运行时才遇到问题。通常，启动模型时，一切都很好。而且我也无法在stackoverflow中适应其他任何log4j问题/答案，因为Repast Simphony中的问题似乎相当具体。
有人遇到过这个问题并解决过吗？还是一个想法，这个RLFA是什么？
注意：在第一步中完全初始化模型时，会发生错误。
谢谢你的帮助

编辑：在Velocity.log中，我找到了此日志记录，其中说缺少VM_global_library.vm-但这是否进一步帮助了？

最佳答案
问题是我忘了在Repast Simphony中定义输出器。
