#This step converts text inputs into numerical representations that the model can process.

#Hugging Face provides tools like DataLoader or DataProcessor for this purpose.

#Fine-tune the model: Train the model on your dataset using the training loop. 
#Adjust the hyperparameters such as learning rate, batch size, and number of epochs to optimize performance. 
#Monitor the validation set metrics to avoid overfitting and select the best model based on these metrics.


#Evaluate the model: Once training is complete, evaluate the performance of your trained model on the test set. Calculate relevant metrics such as accuracy, precision, recall, or F1 score.
#Save and load the model: Save the trained model parameters to disk so that you can later load and use it for predictions without having to retrain from scratch.
