 ## Examples
 
 Here is an example of how to train a model to predict sentiment from text samples (based on [this](https://github.com/dotnet/machinelearning/blob/master/README.md) ML.NET example). The full code for this example is [here](https://github.com/Microsoft/NimbusML-Samples/blob/master/samples/2.1%20%5BText%5D%20Sentiment%20Analysis%201%20-%20Data%20Loading%20with%20Pandas.ipynb).
 
 ```python
+from nimbusml import Pipeline, FileDataStream
+from nimbusml.datasets import get_dataset
+from nimbusml.ensemble import FastTreesBinaryClassifier
+from nimbusml.feature_extraction.text import NGramFeaturizer
+
+train_file = get_dataset('gen_twittertrain').as_filepath()
+test_file = get_dataset('gen_twittertest').as_filepath()
+
+train_data = FileDataStream.read_csv(train_file, sep='\t')
+test_data = FileDataStream.read_csv(test_file, sep='\t')
+
 pipeline = Pipeline([ # nimbusml pipeline
-    NGramFeaturizer(columns={'Features': ['SentimentText']}),
-    FastTreeBinaryClassifier(feature=['Features'], label='Sentiment')
+    NGramFeaturizer(columns={'Features': ['Text']}),
+    FastTreesBinaryClassifier(feature=['Features'], label='Label')
 ])
 
 # fit and predict
-pipeline.fit(data)
-results = pipeline.predict(data)
+pipeline.fit(train_data)
+results = pipeline.predict(test_data)
 ```
 
 Instead of creating an `nimbusml` pipeline, you can also integrate components into Scikit-Learn pipelines:
 
 ```python
+from sklearn.pipeline import Pipeline
+from nimbusml.datasets import get_dataset
+from nimbusml.ensemble import FastTreesBinaryClassifier
+from sklearn.feature_extraction.text import TfidfVectorizer
+import pandas as pd
+
+train_file = get_dataset('gen_twittertrain').as_filepath()
+test_file = get_dataset('gen_twittertest').as_filepath()
+
+train_data = pd.read_csv(train_file, sep='\t')
+test_data = pd.read_csv(test_file, sep='\t')
+
 pipeline = Pipeline([ # sklearn pipeline
     ('tfidf', TfidfVectorizer()), # sklearn transform
-    ('clf', FastTreeBinaryClassifier())]) # nimbusml learner
+    ('clf', FastTreesBinaryClassifier()) # nimbusml learner
 ])
 
 # fit and predict
-pipeline.fit(data)
-results = pipeline.predict(data)
+pipeline.fit(train_data["Text"], train_data["Label"])
+results = pipeline.predict(test_data["Text"])
 ```
