This first line of the code imports the necessary classes from the Hugging Face Transformers library, specifically the T5Tokenizer for tokenization and T5ForConditionalGeneration for loading the pre-trained T5 model.

Then we are instantiating the T5 tokenizer and model. The model is loaded with pre-trained weights, specifically the "t5-small" variant. This pre-trained model can be fine-tuned for various text generation tasks, including summarization.

Then we are passing the sample content that you want to summarize using the pre-trained T5 model.

# Tokenize and encode the content
inputs = tokenizer.encode("summarize: " + content, return_tensors="pt", max_length=512, truncation=True)

print(inputs)

tokenizer.encode: This method is used to tokenize and encode a given text. In this case, the text is "summarize: " + content. The prefix "summarize: " is added to instruct the T5 model to generate a summary of the provided content.
return_tensors="pt": This parameter specifies that the output should be in PyTorch tensor format. The encoded sequence is converted into a PyTorch tensor, making it suitable for input to a PyTorch-based model like T5.
max_length=512: This parameter sets the maximum length of the encoded sequence. If the content is longer than this maximum length after tokenization, it will be truncated to fit.
truncation=True: This parameter indicates that truncation should be applied if the content exceeds the specified maximum length.

After running this code, the variable inputs will contain the tokenized and encoded representation of the input content, ready to be fed into the T5 model for summarization. Find the content of the input variable below.
