  • .NET Version: .NET 5

Describe the bug

When using DetectEntireAnomalyBySrCnn with versions 1.5.4 or greater, no anomalies are detected when running the DetectAnomaly method from the phone call tutorial.

Changing options does nothing. Has anything changed with this algorithm that would suddenly make it stop working after 1.5.4?

If you run the sample using version 1.5.2 with the same data and options it works.
