How do I load a TensorFlow PB model?

How do I load a TensorFlow PB model?

  1. Load a pb file into tensorflow as a graph.
  2. Use the loaded graph as the default graph.
  3. Generate tf records (some binary data format)
  4. Save the loaded graph in tensorboard and then visualize it.
  5. Do inference with loaded graph.
  6. Feed image data into predictive model.
  7. Feed data from tf records into predictive model.

What is PB file in TensorFlow?

pb stands for protobuf. In TensorFlow, the protbuf file contains the graph definition as well as the weights of the model. Thus, a pb file is all you need to be able to run a given trained model. Given a pb file, you can load it as follow.

How do I restore a saved model in TensorFlow?

You can also take this easier way.

  1. Step 1: initialize all your variables. W1 = tf.
  2. Step 2: save the session inside model Saver and save it. model_saver = tf.train.Saver() # Train the model and save it in the end, “saved_models/CNN_New.ckpt”)
  3. Step 3: restore the model.

What is the PB format in TensorFlow?

The .pb format is the protocol buffer (protobuf) format, and in Tensorflow, this format is used to hold models. Protobufs are a general way to store data by Google that is much nicer to transport, as it compacts the data more efficiently and enforces a structure to the data.

What file formats can I save an entire model in TensorFlow?

An entire model can be saved in two different file formats ( SavedModel and HDF5 ). The TensorFlow SavedModel format is the default file format in TF2.x. However, models can be saved in HDF5 format. More details on saving entire models in the two file formats is described below.

Can I resume training from the optimizer-state in TensorFlow?

Since the optimizer-state is recovered, you can resume training from exactly where you left off. An entire model can be saved in two different file formats ( SavedModel and HDF5 ). The TensorFlow SavedModel format is the default file format in TF2.x. However, models can be saved in HDF5 format.

Why is my TensorFlow model getting different results for different weights?

You are freezing the graph properly that is why you are getting different results basically weights are not getting stored in your model. You can use the ( link) for getting a correctly stored graph.
