This library is separated from the main phlower library to provide tensor operations and utilities that can be used independently. It includes tensor objects which have physical dimensions, as well as various tensor operations such as addition, multiplication, contraction, and more.

You can install the library using pip:

pip install phlower-tensor

Here is a simple example of how to use the phlower_tensor library:

import torch
from phlower_tensor import phlower_tensor

# Create two tensors with physical dimensions
velocity = phlower_tensor(torch.rand(100, 3), dimension={"T": -1, "L": 1})
mass = phlower_tensor(torch.rand(100, 1), dimension={"M": 1})

kinetic_energy = 0.5 * mass * (velocity ** 2)
print(kinetic_energy.dimension)
# Output: PhlowerDimensionTensor(T: -2.0, L: 2.0, M: 1.0, I: 0.0, Theta: 0.0, N: 0.0, J: 0.0)

Physical dimensions are represented as dictionaries where keys are dimension symbols (e.g., "L" for length, "T" for time) and values are their respective exponents.
