Creating an instance of babyGPT:

        baby_gpt = babyGPT(
                            max_seq_length = max_seq_length,
                            batch_size = batch_size,
                            embedding_size = embedding_size,
                            num_basic_decoders = num_basic_decoders,
                            num_atten_heads = num_atten_heads,
                            optimizer_params = optimizer_params,
                            num_warmup_steps = num_warmup_steps,
                            masking = masking,
                            verify_text_corpus = False,
                            path_saved_model = {"decoder" : "./saved_decoder",
                                                "embedding_generator" : "./saved_embedding_generator",
                                               },
                          )

Since babyGPT calls on TransformerFG for language modeling, you must also construct an instance of that class:

        xformer = baby_gpt.TransformerFG(
                            max_seq_length = max_seq_length,
                            embedding_size = embedding_size,
                            tokenizer_json = tokenizer_json,
                            num_warmup_steps = num_warmup_steps,
                            optimizer_params = optimizer_params,
                  )

Withing the TransformerFG module, it is the MasterDecoder class that is needed for the next word prediction for the purpose of self-supervised learning:

        master_decoder = baby_gpt.MasterDecoderWithMasking(
                            xformer,
                            num_basic_decoders = num_basic_decoders,
                            num_atten_heads = num_atten_heads,
                            masking = masking
                         )


Finally, here is an instance of the dataloader you're going to need:

        dataloader = baby_gpt.ArticleDatasetWithBufferedContext(
                            gpt = baby_gpt,
                            tokenizer_json = tokenizer_json,
                            context_window_size = context_window_size,
                            context_buffer_size = context_buffer_size,
                            articles_dir = articles_dir,
                     )
