I am running Cobaya but would like to use an initial covmat produced by a Montepython run. When I try to just include it as the covmat, the run fails and I get the error:
. I know the covmat is positive definite, symmetric, and square (it comes from a very well converged MP run).is not a positive-definite, symmetric square matrix
Any insights on why this error is occurring and how it may be addressed would be appreciated!
