How to add custom prompts

Add your method to a file in prompt_strategies. Please see other files as example.
Use your custom file name as the dataset type <prompt_strategies_file>.load_<load_fn>.

Optionally, download some datasets, see data/README.md

Config

See examples for quick start. It is recommended to duplicate and modify to your needs. The most important options are:

model

base_model: ./llama-7b-hf # local or huggingface repo

Note: The code will load the right architecture.

dataset

sequence_len: 2048 # max token length for prompt

# huggingface repo
datasets:
  - path: vicgalle/alpaca-gpt4
    type: alpaca # format from earlier

# huggingface repo with specific configuration/subset
datasets:
  - path: EleutherAI/pile
    name: enron_emails
    type: completion # format from earlier

# local
datasets:
  - path: json
    data_files: data.jsonl # or json
    type: alpaca # format from earlier

loading

load_in_4bit: true
load_in_8bit: true
bf16: true # require >=ampere
fp16: true
tf32: true # require >=ampere
bfloat16: true # require >=ampere, use instead of bf16 when you don't want AMP (automatic mixed precision)
float16: true # use instead of fp16 when you don't want AMP

Note: Repo does not do 4-bit quantization.

Inference

Pass the appropriate flag to the train command:

Pretrained LORA:

--inference --lora_model_dir="./lora-output-dir"

Full weights finetune:

--inference --base_model="./completed-model"

Full weights finetune w/ a prompt from a text file:

cat /tmp/prompt.txt | python scripts/finetune.py configs/your_config.yml \
  --base_model="./completed-model" --inference --prompter=None --load_in_8bit=True

Merge LORA to base

Add below flag to train command above

--merge_lora --lora_model_dir="./completed-model" --load_in_8bit=False --load_in_4bit=False

If you run out of CUDA memory, you can try to merge in system RAM with

CUDA_VISIBLE_DEVICES="" python3 scripts/finetune.py ...

Common Errors 🧰

Cuda out of memory

Please reduce any below

micro_batch_size
eval_batch_size
gradient_accumulation_steps
sequence_len

RuntimeError: expected scalar type Float but found Half

Try set fp16: true

NotImplementedError: No operator found for memory_efficient_attention_forward ...

Try to turn off xformers.
