title: Customer Error: Additional hyperparameters are not allowed - Image classification training- Sagemaker
body: <p>I'm learning image classification with Amazon SageMaker. I was trying to follow their  learning demo <strong>Image classification transfer learning demo</strong> (<code>Image-classification-transfer-learning-highlevel.ipynb</code>)</p>
  
  <p>I got up to Start the training. Executed below.</p>
  
  <pre><code>ic.fit(inputs=data_channels, logs=True)
  </code></pre>
  
  <p>Set the hyper parameters as given in the demo</p>
  
  <pre><code>ic.set_hyperparameters(num_layers=18,
                               use_pretrained_model=1,
                               image_shape = "3,224,224",
                               num_classes=257,
                               num_training_samples=15420,
                               mini_batch_size=128,
                               epochs=1,
                               learning_rate=0.01,
                               precission_dtype='float32')
  </code></pre>
  
  <p>Got the client error</p>
  
  <pre><code>ERROR 140291262150464] Customer Error: Additional hyperparameters are not allowed (u'precission_dtype' was unexpected) (caused by ValidationError)
  
  Caused by: Additional properties are not allowed (u'precission_dtype' was unexpected)
  </code></pre>
  
  <p>Does anyone know how to overcome this? I'm also reporting this to aws support. Posting here for sharing and get a fix. Thanks !</p>
