Incorrect example

Code snippet below the part that should talk about submitting a training script to the local machine uses "MyCluster" as the compute target. Following is the text and corresponding code snippet taken from the documentation:

_The following sample shows how to submit a training script on your local machine._

```
from azureml.core import ScriptRunConfig, Experiment

# create or load an experiment
experiment = Experiment(workspace, 'MyExperiment')
# create or retrieve a compute target
cluster = workspace.compute_targets['MyCluster']
# create or retrieve an environment
env = Environment.get(ws, name='MyEnvironment')
# configure and submit your training run
config = ScriptRunConfig(source_directory='.',
script='train.py',
arguments=['--arg1', arg1_val, '--arg2', arg2_val],
compute_target=cluster,
environment=env)
script_run = experiment.submit(config)
```
