 Suppose that you already have a PyTorch training script called `pytorch-train.py`.
 You can then setup a ``PyTorch`` Estimator with keyword arguments to point to this script and define how SageMaker runs it:
 
-```python
+.. code:: python
 
     from sagemaker.pytorch import PyTorch
 
-    pytorch_estimator = PyTorch(entry_point="pytorch-train.py",
-                                role="SageMakerRole",

 After that, you simply tell the estimator to start a training job and provide an S3 URL
 that is the path to your training data within Amazon S3:
 
-```python
-
-    pytorch_estimator.fit("s3://bucket/path/to/training/data")
+.. code:: python

+    pytorch_estimator.fit('s3://bucket/path/to/training/data')
 
 In the following sections, we'll discuss how to prepare a training script for execution on SageMaker,
 then how to run that script on SageMaker using a ``PyTorch`` Estimator.
