index_to_string(...): Maps tensor of indices into string values based on mapping. (deprecated)

index_to_string_table_from_file(...): Returns a lookup table that maps a Tensor of indices into strings.

index_to_string_table_from_tensor(...): Returns a lookup table that maps a Tensor of indices into strings.

string_to_index(...): Maps tensor of strings into int64 indices based on mapping. (deprecated)

string_to_index_table_from_file(...): Returns a lookup table that converts a string tensor into int64 IDs.

string_to_index_table_from_tensor(...): Returns a lookup table that converts a string tensor into int64 IDs.
