Meet einx: A Python Library that Allows Formulating Many Tensor Operations as Concise Expressions Using Einstein Notation
The field of machine learning and artificial intelligence heavily relies on tensor operations for data manipulation and analysis. Tensors, which are multidimensional arrays, are crucial in representing and processing complex data structures. However, formulating tensor operations can often be cumbersome, requiring lengthy and convoluted code. To simplify this process, a powerful Python library called einx has emerged, allowing users to express tensor operations concisely using Einstein notation.
What is einx?
Einx is a Python library that provides a streamlined approach to formulating tensor operations using Einstein notation. Inspired by the success of einops, einx takes the concept further by offering a fully composable and versatile library for tensor manipulations. It introduces []-notation, which enables users to express tensor operations concisely and intuitively.
Developed by researchers, einx aims to facilitate the formulation of complex tensor operations in a more readable and efficient way. It supports a wide range of operations with Numpy-like naming conventions, making it accessible to users already familiar with popular tensor frameworks such as Numpy, PyTorch, Tensorflow, and Jax.
