How to Use Trained Model In Tensorflow Serving?

9 minutes read

To use a trained model in TensorFlow Serving, you first need to export your trained model in the SavedModel format. This can be done using the tf.saved_model.save() function in TensorFlow.


Once you have exported your model, you can start the TensorFlow Serving server and load your model into it using the --model_base_path flag to specify the directory where your SavedModel is stored.


After starting the server, you can make predictions using the REST API or gRPC interface provided by TensorFlow Serving. You can send input data to the server and receive predictions from the model in real-time.


Overall, using a trained model in TensorFlow Serving involves exporting your model in the SavedModel format, starting the serving server, loading your model into the server, and making predictions using the server's API.

What is the format of input data for a TensorFlow Serving request?

The input data for a TensorFlow Serving request is typically in the form of a protocol buffer message. The message contains the data that needs to be passed to the model for inference. The data can be either in binary format or in JSON format. The specific format of the input data depends on the model architecture and the type of data it is designed to process.


How to call a TensorFlow Serving API endpoint?

To call a TensorFlow Serving API endpoint, you can use a variety of tools or programming languages. One common way is to use Python with the requests library. Here is an example of how you can make a POST request to a TensorFlow Serving API endpoint:

import requests
import json

# Define the endpoint URL
url = 'http://localhost:8501/v1/models/model_name:predict'

# Prepare the request data in the required format
data = {
    "instances": [
        {"input": [1, 2, 3, 4]}
    ]
}

# Convert the data to JSON format
json_data = json.dumps(data)

# Make a POST request to the API endpoint
response = requests.post(url, data=json_data)

# Get the prediction result
prediction_result = response.json()

print(prediction_result)


In this example, you need to replace model_name with the name of your TensorFlow model and ensure that the input data matches the format expected by the model. Make sure to also handle any authentication or other required headers if necessary.


What is the role of gRPC in TensorFlow Serving?

gRPC (Google Remote Procedure Call) is used in TensorFlow Serving as the communication protocol between clients and servers. It allows clients to send requests to the TensorFlow serving server, which then processes the requests and sends back the responses. gRPC is a high-performance, open-source remote procedure call (RPC) framework that is designed for efficient communication between distributed systems.


In TensorFlow Serving, gRPC is used to define the communication protocol for serving machine learning models. Clients can send requests to the server using gRPC, specifying which model to run and what input data to use. The server then processes the request, runs the specified model on the input data, and sends back the results to the client. This allows for efficient and fast communication between clients and servers, making it ideal for serving machine learning models at scale.
