Context
The fix reverts an incorrect application of
shlex.quote()inconvert_params_to_hydra_positional_arg. The initial change was included in heritability estimate batch job, is no longer required.Issue
The bug: String values starting with
{or[(e.g. JSON-like objects/lists) were being wrapped in POSIX shell quotes, turningstep.filter={a: 1}into'step.filter={a: 1}'. Hydra's override grammar is not a shell, so it received the literal single-quote characters as part of the argument, breaking the parse.Implementations
shlex.quote
