Dear Murray

 

I updated the terminology from "Anaconda Launcher" to "Anaconda Navigator"

at the Jwiki as well as on Github README.md. Same for ipython-notebook

to "Jupyter Notebook".

Thanks for pointing me at this.

 

A dying jkernel normally means that there is something wrong with the

installation/configuration of the jkernel components.

Please check the installation instructions.

 

In your original email you are using J806 beta 3. Unfortunately I cannot

check whether this would work with Jupyter or not. My hardware is too

old for J806 / AVX extension :-(

Can anybody confirm that J806 is working (or not) with Jupyter?

 

The problem with Jupyter and Python 2.7 (your 2nd email) is that the

module "jkernel" was not found in the Python 2.7 environment:

 
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python
.app/Contents/MacOS/Python: No module named jkernel [I 11:09:42.308
NotebookApp] KernelRestarter: restarting kernel (1/5)

 

So please try installing the "jkernel" module into the Python 2.7
environment,

or continue to use Python 3.6 which I would recommend.

 

Is the "jkernel" working with J805 at your site?

Please let me know.

 

Best Regards

 

Martin
