Covariance matrix not positive definite

[DYYYYYYYYY]

Hello, when I run v_spendred, I get the following prompt:

Covariance matrix not positive definite - To avoid this, try a higher energy floor (e.g. algo_params.ef=-50) or running the algorithm in slow mode using algo_params.mo = 0

I tried changing the value of algo_params.ef to -50, -40, -30, -20, but still, I tried algo_params.mo = 0 again and found it running for a long time but still running. Why is this so?

Hello,
Sorry for taking a long time to respond. Can you send me the input data that causes the problem (either via GitHub or directly to [email protected])? I'll see if I can find/fix the problem.
