What is PyTorch? A deep dive for engineers (and how to deploy it)

PyTorch, an open-source machine learning framework developed by Meta's AI Research lab, has become a vital tool in deep learning research and AI systems since its release in 2016, thanks to its dynamic computation graphs and seamless integration with Python, allowing for flexible and efficient model development. Unlike frameworks like TensorFlow 1.x, PyTorch's dynamic graph feature enables building computation graphs on-the-fly, which simplifies debugging and enhances model design flexibility. PyTorch's widespread adoption in major ML labs and large-scale production systems is supported by its robust ecosystem, including libraries like TorchVision and TorchAudio, and its compatibility with multiple hardware backends such as CUDA, ROCm, and Metal. However, deploying PyTorch models in production can be challenging due to the complexities of setting up infrastructure, which is where platforms like Northflank come in, offering a streamlined process for deploying containerized workloads with GPU support, autoscaling, and Git-based CI/CD, thereby addressing the deployment challenges and enhancing developer efficiency.
