jupyter_core.command

[#1]

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.

Solved. I had to:  

$ export PATH= /opt/cloudera/parcels/Anaconda-4.0.0/bin:$PATH

I had Python installed before installing Anaconda, and it was clashing.

Could any one explain it little more? I am new to python.

Can you clarify your question?  Do you mean regarding jupyter or what the core was from?

To solve: $ export PATH= /opt/cloudera/parcels/Anaconda-4.0.0/bin:$PATH had Python installed before installing Anaconda, and it was clashing.

I followed the cloudera installation page for anaconda and jupyter and I had the same problem. This worked for an interactive session.  Now I would like to add this to systemd and run this as a service.

cat jupyter-notebook.service
[Unit]
Description=Jupyter notebook

Here is the status after a start attempt
