Jupyter show Python[root] instead of Python 2.7

[dbl001]

1. Any idea why Jupyter shows Python[Root] instead of 'Python 2.7'?
2. How do I update Julia to version 0.5? I built Julia from source and it runs from the shell.
   

OS X 10.11.6
Anaconda2-4.1.1-MacOSX-x86_64
David-Laxers-MacBook-Pro:~ davidlaxer$ conda --version
conda 4.1.11
David-Laxers-MacBook-Pro:~ davidlaxer$ python --version
Python 2.7.12 :: Anaconda 4.1.1 (x86_64)

Any idea why Jupyter shows Python[Root] instead of 'Python 2.7'?

That's an anaconda thing, it show the environment of python kernel. It does automatically list environment, and the default environment append to me named [root].

@damianavila , @bollwyvl can you report things up the continuum chain the [root] is confusing a lot of users, we had a bootcamp monday/tuesday that thought [root] was the user running the kernel.

Can we just change the display_name to be more explicit ? like Python {version} [{env} environment]
Maybe there is already an issue on conda/conda ?

How do I update Julia to version 0.5? I built Julia from source and it runs from the shell.

That's a question for the Julia people, in particular the IJulia repository I guess.

Jupyterlab displays ‘No kernel’ … but Python is really running.

Jupyterlab displays ‘No kernel’ … but Python is really running.

JupyterLab is alpha version, it's likely a bug in JupyterLab,

@Carreau last version of nb_conda_kernels shows Python [default] and Python [conda root] and Python [conda: name_of_env]. That should make things less confusing...
