  "Description": "Perform tensor operations using a concise yet expressive\nsyntax inspired by the Python library of the same name.\nReshape, rearrange, and combine multidimensional arrays for\nscientific computing, machine learning, and data analysis.\nEinops simplifies complex manipulations, making code more\nmaintainable and intuitive. The original implementation is\ndemonstrated in Rogozhnikov (2022)\n<https://openreview.net/forum?id=oapKSVM2bcj>.",
