Features:

• Integrated AWS SQS to facilitate the sending of training requests for machine learning processes.
• Implemented a send_training_request function to structure and send messages to the SQS FIFO queue.
• Developed a process_messages function to receive and delete messages after processing, ensuring that training requests are handled efficiently.
• Created a guide (sqs_setup.md) detailing the setup of AWS SQS for training request handling, including queue creation and IAM permissions.
