-
Model and Tokenizer Initialization:
- Necessary libraries are imported, including Torch and Transformers.
- A pre-trained GPT-2 model along with its associated tokenizer is initialized.
-
Data Preparation:
- A dataset of jokes is loaded from a CSV file, utilizing a custom dataset class.
- The data is preprocessed to prepare it for model training.
-
Model Training:
- The GPT-2 model is trained on the jokes data, with jokes fed into the model in batches.
- Loss is calculated at each iteration to adjust the model weights.
-
Generation of New Jokes:
- Once the model is trained, it is utilized to generate new jokes.
- The generation process iteratively selects the next tokens to complete a joke until a termination condition is met.
-
Model and Results Saving:
- The trained model is saved after each epoch.
- The generated jokes are saved in an output file.
In summary, the code implements a complete process, from data preparation to training a GPT-2 model on a set of jokes, followed by the generation of new jokes using the trained model.
