Why metrics['slaviolations'] can only be 1?

[Jingbo-leo]

Thanks a lot for your open source code. I have some doubts. I found that metrics['slaviolations'] = len(np.where([c.destroyAt > c.sla for c in destroyed])) in the stats.py file. No matter how many c.destroyAt > c.sla, this metrics['slaviolations'] can only be 1 each time. Is this correct?Hope to hear from you, thank you very much.

Thanks for your interest in our project. np.where gives a list of indices where the input condition is true. Thus, len(np.where([...]) would give us the number of completed tasks in that interval for which the destroy time is higher than the service level agreement.

Thank you very much for your reply. I understand what it means. But writing like this will result in len(np.where([...]) can only be 1 each time, no matter how many c.destroyAt > c.sla. The output of an example is as follows.
destroyed = []
[c.destroyAt > c.sla for c in destroyed] output is: []
np.where([c.destroyAt > c.sla for c in destroyed]) output is: (array([], dtype=int64),)
len(np.where([c.destroyAt > c.sla for c in destroyed])) output is : 1

But, what I understand is, when destroyed = [] , the slaviolations should be 0. So I think there is something wrong with the code. Or is my understanding of slaviolations wrong?

Hope to hear from you.

Thanks for raising this. It has been fixed.
