check_shapes

check_shapes is a library for annotating and checking tensor shapes. For example:

import tensorflow as tf

from gpflow.experimental.check_shapes import check_shapes

@tf.function
@check_shapes(
    "features: [batch..., n_features]",
    "weights: [n_features]",
    "return: [batch...]",
)
def linear_model(features: tf.Tensor, weights: tf.Tensor) -> tf.Tensor:
    return tf.einsum("...i,i -> ...", features, weights)

For more information see our documentation.

Installation

The recommended way to install check_shapes is from pypi:
