* add phi modeling from hf * update for packing and use new modeling class for phi * update e2e tests for phi to use new model name * update example phi to also use new phi model name * use AutoModelForCausalLM for phi lora since sample packing isn't supported
Phi
Due to some nuances with the phi code, please use deepspeed when training phi for full finetune.
accelerate launch -m axolotl.cli.train examples/phi/phi-ft.yml --deepspeed deepspeed/zero1.json
# OR
python -m axolotl.cli.train examples/phi/phi-qlora.yml
