gorse gorse-in-one启动时候还有个panic

只在启动时候出现, 不过捕获到了... 就是看着难受 -_-! { "level":"error", "ts":1656313095.142161, "caller":"base/util.go:61", "msg":"panic recovered", "panic":"runtime error: index out of range [-1]", "stacktrace":"github.com/zhenghaoz/gorse/base.CheckPanic /Users/ak47/dec/gorse-master/base/util.go:61 runtime.gopanic /usr/local/go/src/runtime/panic.go:838 runtime.goPanicIndex /usr/local/go/src/runtime/panic.go:89 github.com/zhenghaoz/gorse/base/search.(*IVF).Build.func1 /Users/ak47/dec/gorse-master/base/search/ivf.go:205 github.com/zhenghaoz/gorse/base/parallel.Parallel /Users/ak47/dec/gorse-master/base/parallel/parallel.go:31 github.com/zhenghaoz/gorse/base/search.(*IVF).Build /Users/ak47/dec/gorse-master/base/search/ivf.go:192 github.com/zhenghaoz/gorse/base/search.(*IVFBuilder).Build /Users/ak47/dec/gorse-master/base/search/ivf.go:274 github.com/zhenghaoz/gorse/master.(*Master).findItemNeighborsIVF /Users/ak47/dec/gorse-master/master/tasks.go:386 github.com/zhenghaoz/gorse/master.(*Master).runFindItemNeighborsTask /Users/ak47/dec/gorse-master/master/tasks.go:254 github.com/zhenghaoz/gorse/master.(*Master).runRankingRelatedTasks /Users/ak47/dec/gorse-master/master/tasks.go:857 github.com/zhenghaoz/gorse/master.(*Master).RunPrivilegedTasksLoop /Users/ak47/dec/gorse-master/master/master.go:277" }

这个是数据集为空时候会出现的BUG

这个BUG的深层次原因是计算距离的时候出现了NaN，复现的话需要依赖数据

The deep-seated reason for this bug is that NaN appears when calculating the distance.

如果你愿意共享下数据的话就容易修复了，这个bug需要特定数据触发😂
