PyTorch is a powerful machine learning framework that has taken the data science and developer communities by storm. Based on the Torch library, PyTorch is an open-source software that is free to use and has a wide range of applications, including computer vision and natural language processing.
PyTorch was originally developed by Meta AI, which was later renamed Facebook AI Research (FAIR). The framework was publicly released in January 2017 and has since seen a rapid uptake in the data science and developer community. PyTorch is based on Torch, a scientific computing framework and script language that is in turn based on the Lua programming language. PyTorch has quickly become a popular choice for developers and researchers alike.
PyTorch is used by a wide range of customers, including professional services organizations, startups, and large enterprises. Some of the featured customers of PyTorch include:
- Falkonry, and many others.
Funding, Capital Raised, Estimated Revenue
PyTorch is an open-source software and does not have a traditional funding model. However, PyTorch is backed by Facebook AI Research (FAIR), which provides resources and support for the development of the framework. As of 2021, there is no information available on the estimated revenue of PyTorch.
