LocalGPT is an open-source initiative that allows you to converse with your documents without compromising your privacy. With everything running locally, you can be assured that no data ever leaves your computer. Dive into the world of secure, local document interactions with LocalGPT.
- Utmost Privacy: Your data remains on your computer, ensuring 100% security.
- Versatile Model Support: Seamlessly integrate a variety of open-source models, including HF, GPTQ, GGML, and GGUF.
- Diverse Embeddings: Choose from a range of open-source embeddings.
- Reuse Your LLM: Once downloaded, reuse your LLM without the need for repeated downloads.
- Chat History: Remembers your previous conversations (in a session).
- API: LocalGPT has an API that you can use for building RAG Applications.
- Graphical Interface: LocalGPT comes with two GUIs, one uses the API and the other is standalone (based on streamlit).
- GPU, CPU & MPS Support: Supports multiple platforms out of the box, Chat with your data using
CUDA,CPUorMPSand more!
By selecting the right local models and the power of LangChain you can run the entire RAG pipeline locally, without any data leaving your environment, and with reasonable performance.
ingest.pyusesLangChaintools to parse the document and create embeddings locally usingInstructorEmbeddings. It then stores the result in a local vector database usingChromavector store.run_localGPT.pyuses a local LLM to understand questions and create answers. The context for the answers is extracted from the local vector store using a similarity search to locate the right piece of context from the docs.- You can replace this local LLM with any other LLM from the HuggingFace. Make sure whatever LLM you select is in the HF format.
This project was inspired by the original privateGPT.
- 📥 Clone the repo using git:
git clone https://github.com/PromtEngineer/localGPT.git- 🐍 Install conda for virtual environment management. Create and activate a new virtual environment.
conda create -n localGPT python=3.10.0
conda activate localGPT- 🛠️ Install the dependencies using pip
To set up your environment to run the code, first install all requirements:
pip install -r requirements.txtInstalling LLAMA-CPP :
LocalGPT uses LlamaCpp-Python for GGML (you will need llama-cpp-python <=0.1.76) and GGUF (llama-cpp-python >=0.1.83) models.
If you want to use BLAS or Metal with llama-cpp you can set appropriate flags:
For NVIDIA GPUs support, use cuBLAS
# Example: cuBLAS
CMAKE_ARGS="-DLLAMA_CUBLAS=on" FORCE_CMAKE=1 pip install llama-cpp-python==0.1.83 --no-cache-dirFor Apple Metal (M1/M2) support, use
# Example: METAL
CMAKE_ARGS="-DLLAMA_METAL=on" FORCE_CMAKE=1 pip install llama-cpp-python==0.1.83 --no-cache-dirFor more details, please refer to llama-cpp
Installing the required packages for GPU inference on NVIDIA GPUs, like gcc 11 and CUDA 11, may cause conflicts with other packages in your system.
As an alternative to Conda, you can use Docker with the provided Dockerfile.
It includes CUDA, your system just needs Docker, BuildKit, your NVIDIA GPU driver and the NVIDIA container toolkit.
Build as docker build -t localgpt ., requires BuildKit.
Docker BuildKit does not support GPU during docker build time right now, only during docker run.
Run as docker run -it --mount src="$HOME/.cache",target=/root/.cache,type=bind --gpus=all localgpt.
For testing, this repository comes with Constitution of USA as an example file to use.
Put your files in the SOURCE_DOCUMENTS folder. You can put multiple folders within the SOURCE_DOCUMENTS folder and the code will recursively read your files.
LocalGPT currently supports the following file formats. LocalGPT uses LangChain for loading these file formats. The code in constants.py uses a DOCUMENT_MAP dictionary to map a file format to the corresponding loader. In order to add support for another file format, simply add this dictionary with the file format and the corresponding loader from LangChain.
DOCUMENT_MAP = {
".txt": TextLoader,
".md": TextLoader,
".py": TextLoader,
".pdf": PDFMinerLoader,
".csv": CSVLoader,
".xls": UnstructuredExcelLoader,
".xlsx": UnstructuredExcelLoader,
".docx": Docx2txtLoader,
".doc": Docx2txtLoader,
}Run the following command to ingest all the data.
If you have cuda setup on your system.
python ingest.pyYou will see an output like this:
Use the device type argument to specify a given device.
To run on cpu
python ingest.py --device_type cpuTo run on M1/M2
python ingest.py --device_type mpsUse help for a full list of supported devices.
python ingest.py --helpThis will create a new folder called DB and use it for the newly created vector store. You can ingest as many documents as you want, and all will be accumulated in the local embeddings database.
If you want to start from an empty database, delete the DB and reingest your documents.
Note: When you run this for the first time, it will need internet access to download the embedding model (default: Instructor Embedding). In the subsequent runs, no data will leave your local environment and you can ingest data without internet connection.
In order to chat with your documents, run the following command (by default, it will run on cuda).
python run_localGPT.pyYou can also specify the device type just like ingest.py
python run_localGPT.py --device_type mps # to run on Apple siliconThis will load the ingested vector store and embedding model. You will be presented with a prompt:
> Enter a query:After typing your question, hit enter. LocalGPT will take some time based on your hardware. You will get a response like this below.
Once the answer is generated, you can then ask another question without re-running the script, just wait for the prompt again.
Note: When you run this for the first time, it will need internet connection to download the LLM (default: TheBloke/Llama-2-7b-Chat-GGUF). After that you can turn off your internet connection, and the script inference would still work. No data gets out of your local environment.
Type exit to finish the script.
You can use the --show_sources flag with run_localGPT.py to show which chunks were retrieved by the embedding model. By default, it will show 4 different sources/chunks. You can change the number of sources/chunks
python run_localGPT.py --show_sourcesAnother option is to enable chat history. Note: This is disabled by default and can be enabled by using the --use_history flag. The context window is limited so keep in mind enabling history will use it and might overflow.
python run_localGPT.py --use_historyYou can store user questions and model responses with flag --save_qa into a csv file /local_chat_history/qa_log.csv. Every interaction will be stored.
python run_localGPT.py --save_qa-
Open
constants.pyin an editor of your choice and depending on choice add the LLM you want to use. By default, the following model will be used:MODEL_ID = "TheBloke/Llama-2-7b-Chat-GGUF" MODEL_BASENAME = "llama-2-7b-chat.Q4_K_M.gguf"
-
Open up a terminal and activate your python environment that contains the dependencies installed from requirements.txt.
-
Navigate to the
/LOCALGPTdirectory. -
Run the following command
python run_localGPT_API.py. The API should being to run. -
Wait until everything has loaded in. You should see something like
INFO:werkzeug:Press CTRL+C to quit. -
Open up a second terminal and activate the same python environment.
-
Navigate to the
/LOCALGPT/localGPTUIdirectory. -
Run the command
python localGPTUI.py. -
Open up a web browser and go the address
http://localhost:5111/.
To change the models you will need to set both MODEL_ID and MODEL_BASENAME.
-
Open up
constants.pyin the editor of your choice. -
Change the
MODEL_IDandMODEL_BASENAME. If you are using a quantized model (GGML,GPTQ,GGUF), you will need to provideMODEL_BASENAME. For unquantized models, setMODEL_BASENAMEtoNONE -
There are a number of example models from HuggingFace that have already been tested to be run with the original trained model (ending with HF or have a .bin in its "Files and versions"), and quantized models (ending with GPTQ or have a .no-act-order or .safetensors in its "Files and versions").
-
For models that end with HF or have a .bin inside its "Files and versions" on its HuggingFace page.
- Make sure you have a
MODEL_IDselected. For example ->MODEL_ID = "TheBloke/guanaco-7B-HF" - Go to the HuggingFace Repo
- Make sure you have a
