Text Generation with Custom HuggingFace Model

In this demo we will:

• Launch a pretrained a custom text generation HuggingFace model in a Seldon Deployment

• Send a text input request to get a generated text prediction

The custom HuggingFace text generation model is based on the TinyStories-1M model in the HuggingFace hub.

Create a V1 Seldon Deployment

1. On the Overview page, click on Create new deployment.

2. Enter the deployment details as follows, then click Next:

   Parameter	Value
   Name	hf-custom-tiny-stories
   Namespace	seldon [1]
   Type	Seldon Deployment
   Protocol	Inference V2

3. Configure the default predictor as follows, then click Next:

   Parameter	Value
   Runtime	HuggingFace
   Model Project	default
   Model URI	gs://seldon-models/v1.18.1/huggingface/text-gen-custom-tiny-stories
   Storage Secret	(leave blank/none) [2]
   Model Name	(Leave blank)

4. Fill in the predictor parameters as follows:

   Predictor Parameters	Value
   task	text-generation

5. Click Next for the remaining steps^[3], then click Launch.

1. The

seldon

and

seldon-gitops

namespaces are installed by default, which may not always be available. Please select a namespace which best describes your environment.
2. A secret may be required for private buckets.
3. Additional steps may be required for your specific model.

Get Prediction

1. Click on the hf-custom-tiny-stories deployment created in the previous section to enter the deployment dashboard.

2. Inside the deployment dashboard, click on the Predict button.

3. On the Predict page, enter the following text:

   {
      "inputs": [{
        "name": "args",
        "shape": [1],
        "datatype": "BYTES",
        "data": ["this is a test"]
      }]
   }
   

4. Click the Predict button.

Congratulations, you’ve successfully sent a prediction request using a custom HuggingFace model! 🥳

Next Steps

Why not try our other demos? Or perhaps try running a larger-scale model? You can find one in gs://seldon-models/v1.18.1/huggingface/text-gen-custom-gpt2. However, you may need to request more memory!
