tf.compat.v1.to_bfloat16

Casts a tensor to type bfloat16. (deprecated)

tf.compat.v1.to_bfloat16(
    x, name='ToBFloat16'
)

Migrate to TF2

This name was deprecated and removed in TF2, but has an exact replacement tf.cast(..., tf.bfloat16). There are no further issues with eager execution or tf.function.

Before:

tf.compat.v1.to_bfloat16(tf.constant(3.14, dtype=tf.float32))
<tf.Tensor: shape=(), dtype=bfloat16, numpy=3.14>

After:

tf.cast(tf.constant(3.14, dtype=tf.float32), tf.bfloat16)
<tf.Tensor: shape=(), dtype=bfloat16, numpy=3.14>

Description

Args
x	A Tensor or SparseTensor or IndexedSlices.
name	A name for the operation (optional).

Returns
A Tensor or SparseTensor or IndexedSlices with same shape as x with type bfloat16.

Raises
TypeError	If x cannot be cast to the bfloat16.
