[Persimmon] Add support for persimmon (#26042)
* intiial commit * updates * nits * update conversion script * update conversion script * use path to load * add tips etc * some modeling logic * modeling update * more nits * nits * normal layer norm * update config and doc * nits * update doc remove unused * update * fix inits and stuff * fixup * revert wrong changes * updates * more nits * add default config values to the configuration file * fixup happy * update * 2 tests left * update readmes * more nits * slow test and more documentation * update readme * fix licences * styling * use fast if possible when saving tokenizer * remove todo * remove tokenization tests * small last nits * Apply suggestions from code review Co-authored-by: Matt <Rocketknight1@users.noreply.github.com> * nits to skip the timout doctest * fix integration test * fix test * update eos token * update to allow fast tokenization * styling * fix codeLlama as well for the update post processor * Apply suggestions from code review Co-authored-by: amyeroberts <22614925+amyeroberts@users.noreply.github.com> * add more copied from statements * update * doc passes doctest * remove `# final layer norm?` * change docstring prompot * update * Update README.md Co-authored-by: Sylvain Gugger <35901082+sgugger@users.noreply.github.com> * don't doctest the conversion script as it requires more packages * don't init a model in the config * oups * fix doctest --------- Co-authored-by: Matt <Rocketknight1@users.noreply.github.com> Co-authored-by: amyeroberts <22614925+amyeroberts@users.noreply.github.com> Co-authored-by: Sylvain Gugger <35901082+sgugger@users.noreply.github.com>
