tf.cast(x, dtype, name=None)

tf.cast(x, dtype, name=None)

See the guide: Tensor Transformations > Casting

Casts a tensor to a new type.

The operation casts x (in case of Tensor) or x.values (in case of SparseTensor) to dtype.

For example:

# tensor `a` is [1.8, 2.2], dtype=tf.float
tf.cast(a, tf.int32) ==> [1, 2]  # dtype=tf.int32


  • x: A Tensor or SparseTensor.
  • dtype: The destination type.
  • name: A name for the operation (optional).


A Tensor or SparseTensor with same shape as x.


  • TypeError: If x cannot be cast to the dtype.
