Pairwise distance returns inf on series with near-zero variance

Pairwise distance returns inf on series with near-zero variance: a task in MiMo-V2.6-RL-harbor-code: MiMo-V2.6-RL Code (Harbor) (Harbor dataset). I'm using matrixprofile to compute the pairwise distance on a time series I have, and the output contains inf values where I'd expect finite numbers.
