Welcome to our guide on employing mBART, a pre-trained model by Facebook that’s designed to de-noise multiple languages simultaneously using the BART objective. In this article, we will walk you through the steps to effectively use the mBART model for translating Gujarati to English and vice versa.

What is mBART?

mBART (Multilingual BART) is a powerful model that allows for the translation of multiple languages by leveraging extensive training data. The specific checkpoint we will be discussing here has been fine-tuned using ~60K samples from the Bhasha (pib_v1.3) Gujarati-English parallel corpus, allowing it to provide commendable translation results.

Getting Started with mBART

Follow these straightforward steps to get started:

• Step 1: Install the Necessary Libraries

You’ll need libraries like Hugging Face’s Transformers and PyTorch. Install them using pip:

pip install transformers torch

• Step 2: Load the Pre-trained mBART Model

Use the Hugging Face Transformers library to load the model:

from transformers import MBartForConditionalGeneration, MBartTokenizer

model_name = "facebook/mbart-large-cc25"
tokenizer = MBartTokenizer.from_pretrained(model_name)
model = MBartForConditionalGeneration.from_pretrained(model_name)

• Step 3: Prepare Your Input Text

Tokenize your Gujarati text that you wish to translate:

input_text = "હેય! હું વાસુદેવ ગુપ્તા છું"
inputs = tokenizer(input_text, return_tensors="pt")

• Step 4: Generate Translated Text

Use the model to generate the output:

translated_tokens = model.generate(**inputs)
translated_text = tokenizer.decode(translated_tokens[0], skip_special_tokens=True)

• Step 5: Display the Translated Output

Finally, print out the translated text:

print(translated_text)

Explaining the Code with an Analogy

Think of the process of translating text using mBART as if you were preparing a dish in a restaurant. Each step of cooking corresponds to the code:

• Step 1: Gathering Ingredients – Just like you need the right ingredients (libraries) to create a delightful dish, here you gather libraries that are essential for running the model.
• Step 2: Setting Up the Kitchen – Loading the pre-trained model and tokenizer is akin to organizing your kitchen with necessary tools before you start cooking.
• Step 3: Preparing the Ingredients – You must chop and prepare your ingredients (input text) before cooking. Tokenization is just that for your raw text.
• Step 4: Cooking – This is where the magic happens! Generating translated text with the model is like letting your dish simmer and come together based on the flavor of the ingredients.
• Step 5: Serving the Dish – Finally, once your dish (translated text) is ready, you serve it to the patrons (displaying the output) to enjoy.

Troubleshooting Tips

While working with mBART, you may encounter some issues. Here are a few common troubleshooting tips:

• Issue: Encountering Import Errors
  Solution: Ensure that the required libraries (Transformers, PyTorch) are properly installed.
• Issue: Translation Output Seems Incorrect
  Solution: Double-check the input text for any errors before tokenization, as this can affect the quality of translation.
• Issue: Model Performance is Slow
  Solution: Verify that your environment meets the necessary specifications to optimize performance. Also, consider running the model on a GPU for faster processing.
