How Save Tensorflow Model In Protobuf Format?

4 minutes read

To save a optimized-model-in-tensorflow" class="auto-link" target="_blank">TensorFlow model in the protobuf format, you can use the tf.saved_model.save() function provided by TensorFlow. This function allows you to save the model in a serialized format known as the SavedModel protocol buffer (protobuf) format. This format is optimized for fast loading and distribution of TensorFlow models.


To save a model in protobuf format, you need to first create the model using the TensorFlow library and then call the tf.saved_model.save() function with the model as an argument. This function will save the model to the specified directory in the protobuf format, which includes both the model architecture and the trained weights.


Once the model is saved in the protobuf format, you can easily load it back into TensorFlow using the tf.saved_model.load() function. This allows you to quickly deploy the model for inference or further training without having to retrain the model from scratch.


Overall, saving a TensorFlow model in the protobuf format is a convenient and efficient way to store and distribute deep learning models for various applications.


How to convert a TensorFlow model to a protobuf file?

To convert a TensorFlow model to a protobuf file, you can use the freeze_graph.py script that is provided in the TensorFlow repository. Here are the steps to do this:

  1. First, ensure that you have TensorFlow installed on your system.
  2. Save your TensorFlow model in the saved_model format. You can do this by using the tf.saved_model.save() function in your Python script.
  3. Once you have saved your model, navigate to the TensorFlow repository on GitHub and locate the freeze_graph.py script. You can find it in the tensorflow/python/tools directory.
  4. Run the freeze_graph.py script from the command line, passing in the necessary arguments such as the location of the saved model, the output node names, and the output directory for the protobuf file.
  5. After running the script, you should find a protobuf file created in the specified output directory. This protobuf file contains your TensorFlow model in a format that can be used for deployment or inference.


By following these steps, you can easily convert your TensorFlow model to a protobuf file for further use.


How to compress a TensorFlow model saved in protobuf format?

TensorFlow models saved in protobuf format can be compressed using standard compression algorithms such as gzip or bzip2. Here is a simple example using gzip compression:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
import gzip
import shutil

# Load the TensorFlow model
model_path = 'path_to_your_model/model.pb'
with open(model_path, 'rb') as f:
    model_data = f.read()

# Compress the model using gzip
compressed_model_path = 'compressed_model.pb.gz'
with gzip.open(compressed_model_path, 'wb') as f:
    f.write(model_data)

# Optionally, you can delete the original uncompressed model
shutil.move(compressed_model_path, model_path)


You can also use other compression algorithms like bzip2 by importing and using bz2 module instead of gzip. Remember to update the file extension accordingly when saving the compressed model.


How to check if a TensorFlow model is saved in protobuf format?

To check if a TensorFlow model is saved in protobuf format, you can follow these steps:

  1. Locate the saved model directory on your file system where your TensorFlow model is saved. The saved model directory usually consists of a saved_model.pb file and a variables subdirectory.
  2. Open the saved_model.pb file using a text editor or a tool that can read protobuf files.
  3. Look for the keywords syntax = "proto3"; at the beginning of the file. This indicates that the file is saved in protobuf format version 3.
  4. Search for the Message Name in the file. If you see message names such as Any, DoubleValue, FloatValue, Int64Value, etc., then it is a protobuf format file.
  5. If the file contains serialized structured data in binary format, it is most likely saved in the protobuf format.


By following these steps, you can verify if a TensorFlow model is saved in protobuf format.


How to verify the integrity of a TensorFlow model saved in protobuf format?

One way to verify the integrity of a TensorFlow model saved in protobuf format is to compare the checksum of the saved model file with the checksum of the original model file.


Here are the steps to verify the integrity of a TensorFlow model saved in protobuf format:

  1. Calculate the checksum of the original model file before saving it in protobuf format. This can be done using a checksum tool like md5sum, sha1sum, or shasum.
  2. Save the TensorFlow model in protobuf format.
  3. Calculate the checksum of the saved model file using the same checksum tool used in step 1.
  4. Compare the checksum of the saved model file with the checksum of the original model file. If the checksums match, the integrity of the TensorFlow model is verified.


Another way to verify the integrity of a TensorFlow model saved in protobuf format is to load and validate the model using TensorFlow itself. This can be done by loading the saved model file using TensorFlow's tf.saved_model.load() function and then performing some basic checks on the loaded model to ensure its integrity, such as checking the model's input and output shapes, checking the model's architecture, and running some test predictions to ensure the model is functioning correctly.
