Lost Jupyter27 - How to recover

[kumarmy...@gmail.com]

Until now I was able to create new notebooks either in Jupyter27 or Jupyter35.

For some reason, now I am unable to crteate in Jupyter27.

Following is the message in Anaconda27 shell.

Thanks in advance for your suggestions to get back my Jupyter27!

Best,

Kumar.

Have you been using different conda environments for 27 and 35? If you run "conda info", what active environment does it show, and what Python version does it show?

[anatta]

Actually I do not have both python2 and python kernel now...so says the messages.  Is it a good idea to delete the entire anaconda and reinstall.  If so, please point to me to the right un-installation/re-installation guide/reference!  thansk again. Kumar.+

more details attached.  Thanks for the help.

What commands do you use to launch Jupyter27 and Jupyter35? Are you using "activate py27" and then "jupyter-notebook"?

It's best not to uninstall and reinstall if you can avoid it. If you have to do it, the instructions are here:

https://docs.anaconda.com/anaconda/install/uninstall

https://docs.anaconda.com/anaconda/install/windows

@Will Warner:  tried all your suggestions and from anaconda documentation.  I am not sure if you have seen my attachments provided here in this email chain.  I hoped that someone will have the specific solution for the kernels not loading.  Any way, now the solution is to uninstall and reinstall.  You mentioned that this is  not preferable.  Please explain what precautions that I need to take other than following uninstall documentation you have previously referred here.  Thanks in advance for this help.  Kumar.

You should give the *exact* steps that you followed otherwise we are basically guessing at what you may have done.
