title: How to fix ipykernel_launcher.py: error: unrecognized arguments in jupyter?
body: <p>I am following this tensorflow <a href="https://www.tensorflow.org/get_started/get_started_for_beginners" rel="noreferrer">tutorial</a> after two days setting up the environment I finally could run <code>premade_estimator.py</code> using cmd</p>

  <p>but when I try to run the same code in a jupyter notebook I am getting this error:</p>
  
  <blockquote>
  <pre><code>usage: ipykernel_launcher.py [-h] [--batch_size BATCH_SIZE]
                               [--train_steps TRAIN_STEPS]

  </code></pre>
  </blockquote>
  
  <p>I have tried to fix it without success using:</p>
  
  <pre><code>pip install --ignore-installed --upgrade jupyter
  
  pip install ipykernel
  python -m ipykernel install
  
  conda install notebook ipykernel
  ipython kernelspec install-self
  </code></pre>
  
  <p>Any idea will be appreciate! Thanks!</p>
