:zap: Data classes for custom xarray creation
TL;DR
xarray-custom is a third-party Python package which helps to create custom DataArray classes in the same manner as the Python's native dataclass. Here is an introduction code of what the package provides:
from xarray_custom import ctype, dataarrayclass
@dataarrayclass(accessor='img')
class Image:
"""DataArray class to represent images."""
dims = 'x', 'y'
dtype = float
x: ctype('x', int) = 0
y: ctype('y', int) = 0
def normalize(self):
return self / self.max()
The key features are:
# create a custom DataArray
image = Image([[0, 1], [2, 3]], x=[0, 1], y=[0, 1])
# use a custom method via an accessor
normalized = image.img.normalize()
# create a custom DataArray filled with ones
ones = Image.ones((2, 2), x=[0, 1], y=[0, 1])
- Custom DataArray instances with fixed dimensions, datatype, and coordinates can easily be created.
- NumPy-like special functions like
ones()
are provided as class methods. - Custom DataArray methods can be available via a custom accessor.
