We deploy LLaMA-7B-tuned model online for preview. Due to the high website traffic, sometimes the website may fail to respond. You can also deploy the chatbot followingLocal Deploy.Colab chatbot (shell)We provide a simple shell demo of chatbot with Google Colab's T4/P100/V100 GPU.
Notice that the provided gpt-neo-2.7b model isa rather weak model, which only supports English and may sometimes generate
unsatisfactory responses. To improve the performance, users can use their own
dataset to finetune and obtain a better model with LMFlow. One can also try
other available decoder-only models provided in

LLaMA, GPT2, GPT-Neo, Galactica, have been fully tested. We will support encoder models soon.1.SetupOur package has been fully tested on Linux OS (Ubuntu 20.04). Other OS platforms (MacOS, Windows) are not fully tested.
You may encounter some unexpected errors. You may try it first on a Linux machine or use Google Colab to experience it.gitclonehttps://github.com/OptimalScale/LMFlow.gitcdLMFlow

pipinstall-e.2.Prepare DatasetPlease refer to ourdoc.3. Running Scripts3.1 FinetuningYou can runscripts/run_finetune.shto finetune a GPT-2 base model./scripts/run_finetune.shIf you would like to provide arguments for deepspeed to reflect your machine
settings, you may pass the corresponding deepspeed arguments to the script. For
example,./scripts/run_finetune.sh"--num_gpus=8 --master_port 10001"To enable LoRA finetuning, you may refer to./scripts/run_finetune_with_lora.shwhich can be run in similar manner.For detailed configurations, one may modify these scripts directly. These
scripts actually just call python scriptexamples/finetune.py, which can
be run in following manner,deepspeed${deepspeed_args}\examples/finetune.py\--deepspeedconfigs/ds_config_zero3.json\--bf16\--run_namefinetune_with_lora\--model_name_or_pathfacebook/galactica-1.3b\--num_train_epochs0.01\--learning_rate2e-5\--dataset_path${dataset_path}\--per_device_train_batch_size1\--per_device_eval_batch_size1\--validation_split_percentage0\--logging_steps20\--block_size512\--do_train\--output_diroutput_models/finetune\--overwrite_output_dir\--ddp_timeout72000\--save_steps5000\--dataloader_num_workers1Here we set number of epochs--num_train_epochsto0.01so that the
finetuning process can be finished quickly. If you wish to obtain a model with
better performance, feel free to adjust those hyperparameters. You may runpythonexamples/finetune.py-hto view all possible finetuning arguments. The finetuned model checkpoint will
be saved in the argument specified by--output_dir, which isoutput_models/finetunein the above example.
We followAlpacaandVicunain the model tuning process and serve the model in our web service.3.2 EvaluationOne can directly run evaluation with an existing Hugging Face model, e.g. to run
GPT2 large, one may execute./scripts/run_evaluation.shor run the corresponding python scriptCUDA_VISIBLE_DEVICES=0\deepspeedexamples/evaluate.py\--answer_typemedmcqa\--model_name_or_pathgpt2-large\--dataset_pathdata/MedQA-USMLE/validation\--deepspeedexamples/ds_config.jsonTo load the finetuned model, specify--model_name_or_pathwith the saved
model checkpoint directory path.For LoRA finetuned models, one may refer to./scripts/run_evaluation_with_lora.shThose scripts invoke the examplesexamples/*.pybuilt based on our APIs. For
more API-related examples, one may refer to the methods in the unittesttests.3.3 LMFlow BenchmarkLMFlow Benchmark is an automatic evaluation framework for open-source large language models.
We use negative log likelihood (NLL) as the metric to evaluate different aspects of a language model: chitchat, commonsense reasoning, and instruction following abilities.You can directly run the LMFlow benchmark evaluation to obtain the results to participate in theLLM comparision.
For example, to run GPT2 XL, one may execute./scripts/run_benchmark.sh--model_name_or_pathgpt2-xl--model_name_or_pathis required, you may fill in huggingface model name or local model path here.To check the evaluation results, you may checkbenchmark.login./output_dir/gpt2-xl_lmflow_chat_nll_eval,./output_dir/gpt2-xl_all_nll_evaland./output_dir/gpt2-xl_commonsense_qa_eval.4. Additional Notes4.1 LLaMA CheckpointPlease refer to ourdoc.4.2 DeepSpeed ConfigYou can config the deepspeed under configs. Details can be referred atDeepSpeed Configuration4.3 LLaMA Inference on CPUThanks to the great efforts ofllama.cpp. It is possible for everyone to run their LLaMA models on CPU by 4-bit quantization. We provide a script to convert LLaMA LoRA weights to.ptfiles. You only need to useconvert-pth-to-ggml.pyin llama.cpp to perform quantization.5. Model Release5.1 Medical Model CheckpointsYou can run following script to download our medical model checkpoints :cdoutput_models
bashdownload.shmedical_ckptcd-You can also directly download our model via google drive link :medical_ckpt.tar.gz5.2 Instruction Model CheckpointsSimilarly, you can run following script to download our instruction model checkpoints :cdoutput_models
bashdownload.shinstruction_ckptcd-You can also directly download our model via google drive link :instruction_ckpt.tar.gz5.3 Reproduce the resultAfter downloading the model checkpoints, you can merge the lora model into the base model viapython examples/merge_lora.py \
    --model_name_or_path {huggingface-model-name-or-path-to-base-model} \
    --lora_model_path {path-to-lora-model} \
    --output_model_path {path-to-merged-model}Or you can replace the--lora_model_pathwithoutput_models/instruction_ckpt/llama7b-lora(example for llama-7b for instruction) and replace--model_name_or_pathwith your converted llama model insideLMFlow/scripts/run_evaluation_with_lora.shand run this shell script to reproduce the result.For full model deltas, such as robin-7b-v2-delta, you may use the delta merge script to obtain the full model,python utils/apply_delta.py \
    --base-model-path {huggingface-model-name-or-path-to-base-model} \
    --delta-path {path-to-delta-model} \
    --target-model-path {path-to-merged-model}Then you can check the model performance at ourDoc.DocumentationPlease refer to ourDocumentationfor more API reference and experimental results.VisionHello there! We are excited to announce the upcoming release of our code repository that includes a complete LLM training process, enabling users to quickly build their own language models and train them effectively.Our code repository is not just a simple model; it includes the complete training workflow, model optimization, and testing tools. You can use it to build various types of language models, including conversation models, question-answering models, and text generation models, among others.Moreover, we aim to create an open and democratic LLM sharing platform where people can share their checkpoints and experiences to collectively improve the skills of the community. We welcome anyone who is interested in LLM to participate and join us in building an open and friendly community!Whether you are a beginner or an expert, we believe that you can benefit from this platform. Let's work together to build a vibrant and innovative LLM community!AcknowledgementLMFlow draws inspiration from various studies, including but not limited to:Alpaca:https://github.com/tatsu-lab/stanford_alpacaVicuna:https://github.com/lm-sys/FastChatSupportIf you need any help, please submit aGithubissue.ContributorsCitationIf you find this repository useful, please consider giving ⭐ and citing:@misc{lmflow,
