Segmentation Fault when running rbeast in a for-loop with hasOutlier=True #32

Open marinasie opened 1 month ago

marinasie commented 1 month ago

Hi everyone,

I've been using your algorithm to detect change points in bird populations, and I'm loving the results so far!

When I run BEAST like this without a for-loop, it works perfectly: o = rb.beast(y, deltat='7 days', period='1 year', hasOutlier=True) However, when I introduce a for-loop around it to calculate change points for multiple time series, the first iteration executes without any issues, but I encounter a segmentation fault during the second iteration. With hasOutlier=False, the loop works fine.

I'm using the latest version of the Python package on my Mac, and all my time series have a length of 260.

Do you have any suggestions on how I might resolve this issue? Thank you!

Marina,

Thanks for the important feedback. Unfortunately there is no way to tell what went wrong without reproducing the error on my end. If possible, can you share a sample dataset plus the failing script for me to test-run it and figure out the cause?

Thanks. Kaiguang
