The following are the GPU memory requirements for different features, the difference lies only in whether the options are turned on.
Configuration Example | GPU mem Requirements | Description | Verified on Linux |
---|---|---|---|
config-cpu.ini | - | Use siliconcloud API for text only |
|
config-2G.ini | 2GB | Use openai API (such as kimi, deepseek and stepfun to search for text only | |
config-multimodal.ini | 10GB | Use openai API for LLM, image and text retrieval | |
[Standard Edition] config.ini | 19GB | Local deployment of LLM, single modality | |
config-advanced.ini | 80GB | local LLM, anaphora resolution, single modality, practical for WeChat group |
We take the standard edition (local running LLM, text retrieval) as an introduction example. Other versions are just different in configuration options.

Use mmpose documents to build the mmpose knowledge base and filtering questions. If you have your own documents, just put them under repodir
.
Copy and execute all the following commands (including the '#' symbol).
# Download the knowledge base, we only take the documents of mmpose as an example. You can put any of your own documents under `repodir`
cd HuixiangDou
mkdir repodir
git clone https://github.com/open-mmlab/mmpose --depth=1 repodir/mmpose
# Save the features of repodir to workdir, and update the positive and negative example thresholds into `config.ini`
mkdir workdir
python3 -m huixiangdou.service.feature_store
After running, test with python3 -m huixiangdou.main --standalone
. At this time, reply to mmpose related questions (related to the knowledge base), while not responding to weather questions.
python3 -m huixiangdou.main --standalone

Note
💡 Also run a simple Web UI with gradio
:
python3 -m huixiangdou.gradio
output.mp4
Or run a server to listen 23333, default pipeline is chat_with_repo
:
python3 -m huixiangdou.server
# test async API
curl -X POST http://127.0.0.1:23333/huixiangdou_stream -H "Content-Type: application/json" -d '{"text": "how to install mmpose","image": ""}'
# cURL sync API
curl -X POST http://127.0.0.1:23333/huixiangdou_inference -H "Content-Type: application/json" -d '{"text": "how to install mmpose","image": ""}'
Please update the repodir
documents, good_questions and bad_questions, and try your own domain knowledge (medical, financial, power, etc.).
- One-way sending to Feishu group
- Two-way Feishu group receiving and sending, recalling
- Personal WeChat Android access
- Personal WeChat wkteam access
We provide typescript
front-end and python
back-end source code:
- Multi-tenant management supported
- Zero programming access to Feishu and WeChat
- k8s friendly
Same as OpenXlab APP, please read the web deployment document.
If there is no GPU available, model inference can be completed using the siliconcloud API.
Taking docker miniconda+Python3.11 as an example, install CPU dependencies and run:
# Start container
docker run -v /path/to/huixiangdou:/huixiangdou -p 7860:7860 -p 23333:23333 -it continuumio/miniconda3 /bin/bash
# Install dependencies
apt update
apt install python-dev libxml2-dev libxslt1-dev antiword unrtf poppler-utils pstotext tesseract-ocr flac ffmpeg lame libmad0 libsox-fmt-mp3 sox libjpeg-dev swig libpulse-dev
python3 -m pip install -r requirements-cpu.txt
# Establish knowledge base
python3 -m huixiangdou.service.feature_store --config_path config-cpu.ini
# Q&A test
python3 -m huixiangdou.main --standalone --config_path config-cpu.ini
# gradio UI
python3 -m huixiangdou.gradio --config_path config-cpu.ini
If you find the installation too slow, a pre-installed image is provided in Docker Hub. Simply replace it when starting the docker.
If your GPU mem exceeds 1.8G, or you pursue cost-effectiveness. This configuration discards the local LLM and uses remote LLM instead, which is the same as the standard edition.
Take siliconcloud
as an example, fill in the API TOKEN applied from the official website into config-2G.ini
# config-2G.ini
[llm]
enable_local = 0 # Turn off local LLM
enable_remote = 1 # Only use remote
..
remote_type = "siliconcloud" # Choose siliconcloud
remote_api_key = "YOUR-API-KEY-HERE" # Your API key
remote_llm_model = "alibaba/Qwen1.5-110B-Chat"
Note
Execute the following to get the Q&A results
python3 -m huixiangdou.main --standalone --config-path config-2G.ini # Start all services at once
If you have 10G GPU mem, you can further support image and text retrieval. Just modify the model used in config.ini.
# config-multimodal.ini
# !!! Download `https://huggingface.co/BAAI/bge-visualized/blob/main/Visualized_m3.pth` to `bge-m3` folder !!!
embedding_model_path = "BAAI/bge-m3"
reranker_model_path = "BAAI/bge-reranker-v2-minicpm-layerwise"
Note:
- You need to manually download Visualized_m3.pth to the bge-m3 directory
- Install FlagEmbedding on main branch, we have made bugfix. Here you can download
bpe_simple_vocab_16e6.txt.gz
- Install requirments-multimodal.txt
Run gradio to test, see the image and text retrieval result here.
python3 tests/test_query_gradio.py
The "HuiXiangDou" in the WeChat experience group has enabled all features:
- Serper search and SourceGraph search enhancement
- Group chat images, WeChat public account parsing
- Text coreference resolution
- Hybrid LLM
- Knowledge base is related to openmmlab's 12 repositories (1700 documents), refusing small talk
Please read the following topics:
- Hybrid knowledge graph and dense retrieval
- Refer to config-advanced.ini configuration to improve effects
- Group chat scenario anaphora resolution training
- Use wkteam WeChat access, integrate images, public account parsing, and anaphora resolution
- Use rag.py to annotate SFT training data
Contributors have provided Android tools to interact with WeChat. The solution is based on system-level APIs, and in principle, it can control any UI (not limited to communication software).
-
What if the robot is too cold/too chatty?
- Fill in the questions that should be answered in the real scenario into
resource/good_questions.json
, and fill the ones that should be rejected intoresource/bad_questions.json
. - Adjust the theme content in
repodir
to ensure that the markdown documents in the main library do not contain irrelevant content.
Re-run
feature_store
to update thresholds and feature libraries.⚠️ You can directly modifyreject_throttle
in config.ini. Generally speaking, 0.5 is a high value; 0.2 is too low. - Fill in the questions that should be answered in the real scenario into
-
Launch is normal, but out of memory during runtime?
LLM long text based on transformers structure requires more memory. At this time, kv cache quantization needs to be done on the model, such as lmdeploy quantization description. Then use docker to independently deploy Hybrid LLM Service.
-
How to access other local LLM / After access, the effect is not ideal?
- Open hybrid llm service, add a new LLM inference implementation.
- Refer to test_intention_prompt and test data, adjust prompt and threshold for the new model, and update them into prompt.py.
-
What if the response is too slow/request always fails?
- Refer to hybrid llm service to add exponential backoff and retransmission.
- Replace local LLM with an inference framework such as lmdeploy, instead of the native huggingface/transformers.
-
What if the GPU memory is too low?
At this time, it is impossible to run local LLM, and only remote LLM can be used in conjunction with text2vec to execute the pipeline. Please make sure that
config.ini
only uses remote LLM and turn off local LLM.
