I am running some long parallel chains on a cluster where instead of printing the screen output, it is saved to a file. I have a limited space for these files, and I am getting repeated warnings:
Informational Message: The current Metropolis proposal is about to be rejected because of the following issue: Exception: cholesky_decompose: Matrix m is not positive definite (in 'unknown file name' at line 122) If this warning occurs sporadically, such as for highly constrained variable types like covariance matrices, then the sampler is fine, but if this warning occurs often then your model may be either severely ill-conditioned or misspecified.
That is the case, so the warnings are expected, the only problem being that they are creating large files for my quota instead of the brief percentage progress.
I would like to suppress these warnings, is that possible?
