* fix for parallelism config from trainer * fix handling of parallelism_config w accelerate * add todo for removal * update to latest axolotl-contribs-mit for optimizer fix too * synchronize training after checkpoint save * dir spelling * use latest accelerate main * fix to not use partial state parallelism_config * more fixeS * use most recent accelerate fix * fix cpu_ram_efficient_loading to meta devices from rank 0 to prevent CPU RAM oom * improve handling of broadcasting fsdp2 state dict * support for openai chat template with thinking key as the reasoning trace * address PR feedback * refactor to remove dependency on PartialState for parallelism config * bump accelerate, gptoss fixes * limit meta fixes to fsdp2 for now * fixes for gpt oss * fixup examples, don't use cpu-ram-efficient-loading for now * remove problematic barrier * patch parallelism config * reorder comparison * device mesh fixes * make pure CP work * lint
