tf.string_to_hash_bucket(string_tensor, num_buckets, name=None)

tf.string_to_hash_bucket(string_tensor, num_buckets, name=None)

See the guide: Strings > Hashing

Converts each string in the input Tensor to its hash mod by a number of buckets.

The hash function is deterministic on the content of the string within the process.

Note that the hash function may change from time to time. This functionality will be deprecated and it's recommended to use tf.string_to_hash_bucket_fast() or tf.string_to_hash_bucket_strong().


  • string_tensor: A Tensor of type string.
  • num_buckets: An int that is >= 1. The number of buckets.
  • name: A name for the operation (optional).


A Tensor of type int64. A Tensor of the same shape as the input string_tensor.
