The mbart-large-50-verbalization model is a specialized transformer designed to convert structured Ukrainian text into fully expanded forms, tailored specifically for Text-to-Speech (TTS) applications. This guide will help you understand how to set up and use this model effectively, as well as troubleshooting tips if you run into any issues.

Understanding the Model

The mbart-large-50-verbalization model is fine-tuned from the facebook/mbart-large-50 architecture, recognized for its robust performance in translation and text generation across multiple languages. Imagine it like a skilled translator that not only understands words but can transform data (like dates and numbers) into a natural, conversational format.

Setup Instructions

Step 1: Install Required Libraries

Ensure that you have the necessary libraries for this model:

• transformers
• datasets
• torch

You can install them using:

pip install transformers datasets torch

Step 2: Load the Model and Tokenizer

Begin by loading the model and tokenizer in your Python environment:

from transformers import MBartForConditionalGeneration, AutoTokenizer
import torch

model_name = "skypro1111/mbart-large-50-verbalization"
device = torch.cuda.is_available() if "cuda" else "cpu"

model = MBartForConditionalGeneration.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name)

Step 3: Prepare Your Input Text

Next, let’s prepare the Ukrainian text you want to verbalize. For example:

input_text = "Цей додаток вийде 15.06.2025."

Step 4: Encoding and Generating Output

Now, encode your input and generate the verbalized output:

encoded_input = tokenizer(input_text, return_tensors="pt", padding=True, truncation=True, max_length=1024).to(device)
output_ids = model.generate(**encoded_input, max_length=1024, num_beams=5, early_stopping=True)
output_text = tokenizer.decode(output_ids[0], skip_special_tokens=True)

print(output_text)

Troubleshooting Tips

If you encounter any issues while using the mbart-large-50-verbalization model, here are some common troubleshooting ideas:

• Dependency Errors: Double-check that all required libraries are properly installed. Use pip list to inspect installed packages.
• Memory Issues: If you’re using a GPU, make sure you’ve allocated enough memory. You might want to reduce the batch size.
• Model Not Found: Ensure that you’ve correctly typed the model name: skypro1111/mbart-large-50-verbalization.
• Input Format Errors: Confirm that your input is correctly formatted as a string.
