I'm trying to install Jupyter using these instructions http://www.cloudera.com/documentation/enterprise/5-6-x/topics/spark_ipython.html.   I've have installed under Anaconda and when I try to run pyspark ( from section 

Starting a Notebook with PySpark) I receive the following error:  

$ pyspark

Traceback (most recent call last):

  File "/opt/cloudera/parcels/Anaconda/bin/jupyter", line 4, in <module>

    from jupyter_core.command import main

ImportError: No module named jupyter_core.command

Any help is appreciated.
