- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
Start with emcee/moves/red_blue.py at line 99 and inspect how lnpdiff uses f, nlp, and state.log_prob[j]. The report does not include the user’s sampling code or log-probability function, so establish a minimal reproduction before changing behavior. Done means identifying the source of the invalid value and documenting or testing the resulting fix.
