In our increasingly interconnected world, the ability to translate languages swiftly and accurately sets the foundation for effective communication. The mbart-large-50 model, specifically fine-tuned for translating English to Marathi, is a powerful tool that can help bridge the language gap. This blog post will guide you through using this model, highlight its intended uses and limitations, and provide troubleshooting ideas along the way.

Setting Up the Model

To harness the capabilities of the mbart-large-50 model for English to Marathi translation, you first need to set up the appropriate Python environment. You’ll be using the Transformers library. Below are the steps to get started:

1. Install Required Libraries

• Ensure you have Python installed on your machine.
• Use pip to install the Transformers library by running the following command:

pip install transformers

2. Importing the Model

Now you’re ready to import the model and tokenizer. Here’s how you can get started:

from transformers import MBartForConditionalGeneration, MBart50TokenizerFast

3. Loading the Model and Tokenizer

Next, load the fine-tuned model and tokenizer you will be working with:

model = MBartForConditionalGeneration.from_pretrained('shivammbart-large-50-finetuned-en-mr')
tokenizer = MBart50TokenizerFast.from_pretrained('shivammbart-large-50-finetuned-en-mr', src_lang='en_XX', tgt_lang='mr_IN')

4. Inputting the English Sentence

To translate an English sentence into Marathi, define your input:

english_input_sentence = "The Prime Minister said that cleanliness, or Swachhta, is one of the most important aspects of preventive healthcare."

5. Tokenizing Input and Generating Output

Here’s where the magic happens! The model will take your tokenized input and generate the Marathi translation:

model_inputs = tokenizer(english_input_sentence, return_tensors='pt')
generated_tokens = model.generate(
    **model_inputs,
    forced_bos_token_id=tokenizer.lang_code_to_id['mr_IN'])

6. Decoding and Displaying the Marathi Output

Lastly, decode the generated tokens to get the final Marathi translation:

marathi_output_sentence = tokenizer.batch_decode(generated_tokens, skip_special_tokens=True)
print(marathi_output_sentence)

Output:

The output would be:

स्वच्छता हा प्रतिबंधात्मक आरोग्य सेवेतील सर्वात महत्त्वाचा पैलू आहे, असे पंतप्रधान म्हणाले.

Understanding the Code – An Analogy

Imagine you’re a chef cooking up a unique dish in your kitchen (your programming environment). Each ingredient represents a line of code, and the recipe as a whole showcases how to deliver the final meal (the end output).

1. You start by gathering your ingredients (installing necessary libraries).

2. You then read the recipe (importing and loading the model and tokenizer).

3. Next, you prep your ingredients (inputting the English sentence).

4. As you mix and cook (tokenizing and generating output), you follow specific instructions to ensure a delicious result.

5. Finally, you plate your dish (decoding and displaying the translation) for everyone to enjoy!

Limitations

While the mbart-large-50 model can be incredibly useful for English to Marathi translations, it’s crucial to recognize its limitations:

• The model was trained with limited epochs on Google Colab, which may affect the translation quality.
• It performs best with common phrases and may struggle with idiomatic expressions.

Troubleshooting

If you encounter issues while using the model, consider the following ideas:

• Ensure all required libraries and dependencies are correctly installed.
• Check that you’re using the correct model and tokenizer names.
• Review your input sentence for any punctuation or spelling errors that may interfere with tokenization.
