title: Load TensorFlow model from .pb file
body: <p><strong>Background:</strong> I have my TensorFlow model stored in a directory with the folders/files: assets, variables, and saved_model.pb. All I need to do with this model is make predictions (no training) so I do not need the assets and variables folders. The saved_model.pb file is much smaller than the variables folder and storage is extremely important to me.</p>
  <p><strong>Question:</strong> How could I load my TensorFlow model from the saved_model.pb file only (no variables or assets folders) in Tensorflow 2.3?</p>
  <p>This is my file structure:</p>
  <pre><code>saved_models
  ├── model_1
  |   ├── assets
  |   |   └── (this is an empty folder)
  |   ├── saved_model.pb
  |   ├── variables
  |   |   ├── variables.data-00000-of-00001
  |   |   └── variables.index
  </code></pre>
