How to input the model with the DT_STRING type

[Alex555github]

Hi, зlease tell me how to enter such a model:

signature_def['serving_default']:
The given SavedModel SignatureDef contains the following input(s):
inputs['text_vectorization_input'] tensor_info:
dtype: DT_STRING
shape: (-1)
name: serving_default_text_vectorization_input:0
The given SavedModel SignatureDef contains the following output(s):
outputs['dense_1'] tensor_info:
dtype: DT_FLOAT
shape: (-1, 1)
name: StatefulPartitionedCall_1:0
Method name is: tensorflow/serving/predict

submit data of type string. If you don't mind, I can give you a code example in C++. Thank you very much in advance!
