DocSum¶
Helm chart for deploying DocSum service.
DocSum depends on LLM microservice, refer to llm-uservice for more config details.
Installing the Chart¶
To install the chart, run the following:
cd GenAIInfra/helm-charts/
./update_dependency.sh
helm dependency update docsum
export HFTOKEN="insert-your-huggingface-token-here"
export MODELDIR="/mnt/opea-models"
export MODELNAME="Intel/neural-chat-7b-v3-3"
helm install docsum docsum --set global.HUGGINGFACEHUB_API_TOKEN=${HFTOKEN} --set global.modelUseHostPath=${MODELDIR} --set tgi.LLM_MODEL_ID=${MODELNAME}
# To use Gaudi device
# helm install docsum docsum --set global.HUGGINGFACEHUB_API_TOKEN=${HFTOKEN} --values docsum/gaudi-values.yaml
Verify¶
To verify the installation, run the command kubectl get pod
to make sure all pods are running.
Curl command and UI are the two options that can be leveraged to verify the result.
Verify the workload through curl command¶
Then run the command kubectl port-forward svc/docsum 8888:8888
to expose the DocSum service for access.
Open another terminal and run the following command to verify the service if working:
curl http://localhost:8888/v1/docsum \
-H 'Content-Type: application/json' \
-d '{"messages": "Text Embeddings Inference (TEI) is a toolkit for deploying and serving open source text embeddings and sequence classification models. TEI enables high-performance extraction for the most popular models, including FlagEmbedding, Ember, GTE and E5."}'
Verify the workload through UI¶
The UI has already been installed via the Helm chart. To access it, use the external IP of one your Kubernetes node along with the NGINX port. You can find the NGINX port using the following command:
export port=$(kubectl get service docsum-nginx --output='jsonpath={.spec.ports[0].nodePort}')
echo $port
Open a browser to access http://<k8s-node-ip-address>:${port}
to play with the ChatQnA workload.
