title: What is the SageMaker TensorFlow SavedModel export format?
body: <p>I'm new to AWS SageMaker TensorFlow 1.11.0 script mode. Been looking around the documentation for a while and can't seem to find the folder structure to export the model in after training. All I know is that I'm suppose to export to the directory specified in the env variable "SM_MODEL_DIR" and that the format is SavedModel.</p>
  
  <p>I've used <code>tf.saved_model.simple_save</code> to export in the following folder structure:</p>
  
  <pre><code>- model.tar.gz
  -- saved_model.pb
  -- variables
  --- variables.index
  --- variables.data-00000-of-00001
  </code></pre>
  
  <p>But upon deploying, I get the error:</p>
  
  <pre><code>Traceback (most recent call last):
  File "/sagemaker/serve.py", line 189, in &lt;module&gt;
  ServiceManager().start()
  File "/sagemaker/serve.py", line 163, in start
  self._create_tfs_config()
  File "/sagemaker/serve.py", line 53, in _create_tfs_config
  raise ValueError('no SavedModel bundles found!')
  </code></pre>
  
  <p>any help would be nice. Thx</p>
