title: how can i test my model using different dataset in machine learning
body: <p>i m new in machine learning and i am create a one small project using CountVectorizer model. i am split my data to 80% -20%. 80% for training model and 20% for testing model. my model work properly run on 20% test data but can i used to test my model on different data set that is similar to training data set?</p>
  <p>i am using joblib  for dump and load my model.</p>
  <pre><code>from joblib import dump, load
  dump(pipe, filename)
  
  loaded_model = load('filename')
  </code></pre>
  <p>my question is how i directly test my model using different dataset?</p>
