title: Rasa nlu model is not working. AttributeError: 'str' object has no attribute 'load'
body: <p>First of all i want to say that i am completly new to this topic.
  I was trying to build a Chatbot with Rasa.
  While following a tutorial on YouTube :<a href="https://www.youtube.com/watch?v=xu6D_vLP5vY&amp;t=514s" rel="nofollow noreferrer">https://www.youtube.com/watch?v=xu6D_vLP5vY&amp;t=514s</a>
  I came across a problem with the nlu_model.py file.</p>
  
  <p>Because the tutorial is made a while ago, there have been some changes made. 
  I tried the old and the new Version and both won't work for me.</p>
  
  <pre class="lang-py prettyprint-override"><code>from rasa_nlu.training_data import load_data
  from rasa_nlu import config
  from rasa_nlu.model import Trainer
  
  def train_nlu(data, config, model_dir):
      training_data = load_data(data)
      trainer = Trainer(config.load(configs))
      trainer.train(training_data)
      model_directory = trainer.persist(model_dir, fixed_model_name = 'weathernlu')
  
  if __name__ == '__main__':
      train_nlu('./data/data.json', 'config_spacy.json', './models/nlu')
  </code></pre>
  
  <p>this is my nlu_model.py file</p>
  
  <pre><code>C:\Users\Yannic\Documents\Waetherbot&gt;python nlu_model.py
  Traceback (most recent call last):
    File "nlu_model.py", line 12, in &lt;module&gt;
      train_nlu('./data/data.json', 'config_spacy.json', './models/nlu')
    File "nlu_model.py", line 7, in train_nlu
      trainer = Trainer(config.load(configs))
  AttributeError: 'str' object has no attribute 'load'
  </code></pre>
  
  <p>And this is my Shell Output.
  I really hope i can get some help.</p>
