    "This sample shows how use `text-classification` components from the `azureml` system registry to fine tune a model to detect emotions using emotion dataset. [Serverless compute](https://learn.microsoft.com/en-us/azure/machine-learning/how-to-use-serverless-compute?view=azureml-api-2&tabs=python) is used to fine-tune the model. We then deploy the fine tuned model to an online endpoint for real time inference. The model is trained on tiny sample of the dataset with a small number of epochs to illustrate the fine tuning approach.\n",
