Intent Detection Microservice by TGI

🚀1. Start Microservice with Python（Option 1）

1.1 Install Requirements

pip install -r requirements.txt

1.2 Start TGI Service

export HUGGINGFACEHUB_API_TOKEN=${your_hf_api_token}
docker run -p 8008:80 -v ./data:/data --name tgi_service --shm-size 1g ghcr.io/huggingface/text-generation-inference:1.4 --model-id ${your_hf_llm_model}

1.3 Verify the TGI Service

curl http://${your_ip}:8008/generate \
  -X POST \
  -d '{"inputs":"What is Deep Learning?","parameters":{"max_new_tokens":17, "do_sample": true}}' \
  -H 'Content-Type: application/json'

1.4 Setup Environment Variables

export TGI_LLM_ENDPOINT="http://${your_ip}:8008"

1.5 Start Intent Detection Microservice with Python Script

Start intent detection microservice with below command.

cd ../../../
cp comps/intent_detection/langchain/intent_detection.py .
python intent_detection.py

🚀2. Start Microservice with Docker (Option 2)

2.1 Start TGI Service

Please refer to 1.2.

2.2 Setup Environment Variables

export TGI_LLM_ENDPOINT="http://${your_ip}:8008"
