荒谬的错误“错误10:参数1数组不能为空." [英] Absurd error "Error 10: Argument 1 Array must not be empty."

问题描述

我是ML Studio的新手，但是我真的为这个问题的错误而疯狂.

I'm new to ML Studio but I'm really getting crazy with the error in this subject.

我的航班延误预测测试实验得到了完美的编译，并返回了很好的准确性(在270K样本上接近99％).

My test experiment on flights delay prediction is perfectly compiled and returns a nice accuracy (nearly 99% on 270K samples).

但是，当我发布为网络服务(有效)并尝试使用它时，有时"它返回上面的错误.

However when I publish as a web service (which works) and try to use it, "sometimes" it return the error above.

但是，有时它可以完美地工作！！

However, other times it perfectly works!!

我不知道这是不是原因，但是，如果我只是运行在线测试并将参数设置为-3到+3之间的任何值，它就可以工作.相反，如果它是4或更高(正数或负数)，则会出现错误.由于该信息仅代表 在出发时间"中，您可以想象可能超过4(分钟).无论如何，我不明白为什么会得到它，因为即使我进行了数千次而不是1次实验，我也从未在实验中遇到此错误，其中大多数确实具有更高的价值 大于3.

I don't know if this is the reason, however if I just run an online test and set a parameter to any value between -3 and +3, it works. Instead, if it is 4 or higher (either in positive or negative), the error appears. Since that information just represents the "time in departure", you can imagine that's likely more than 4 (mintues). Anyway I don't catch why I get it, since I never get this error in my experiment even if I run thousand of experiments rather than 1, most of which DO have a value higher than 3.

非常感谢您提供任何提示.

Thank you very much for any hint.
