L2 Loss.

Computes half the L2 norm of a tensor without the sqrt:

output = sum(t ** 2) / 2


#### Args:

• t: A Tensor. Must be one of the following types: half, bfloat16, float32, float64. Typically 2-D, but may have any dimensions.
• name: A name for the operation (optional).

#### Returns:

A Tensor. Has the same type as t.
