treex.sequence

Creates a function that applies a sequence of callables to an input.

Examples:

class Block(tx.Module):
    linear: tx.Linear
    batch_norm: tx.BatchNorm
    dropout: tx.Dropout
    ...

    def __call__(self, x: jnp.ndarray) -> jnp.ndarray:
        return tx.sequence(
            self.linear,
            self.batch_norm,
            self.dropout,
            jax.nn.relu,
        )(x)

Parameters:

Name	Type	Description	Default
*layers	Callable[..., jax._src.numpy.lax_numpy.ndarray]	A sequence of callables to apply.	()
