Jupyter notebook

[twanmal]

Hello,
I wonder why Jupyter recommend the anaconda installation and does not ask to install python variables because if you follow the anconda installation, it recommends to not update the environment variables. Then there is surely a problem while trying "jupyter notebook" in the command line...

Hello twanmal,

could you please explain the problem you encountered?

If the Anaconda environment is correctly initialized, the notebook server in that environment should have no problem to start with a localhost setup. With correctly initialized, I mean that you executed "source activate <environment>" (or the Windows equivalent) in the command line before trying "jupyter notebook".

cheers,

  Roland

Hello Roland,

the point is this one

1) on the Jupyter website they strongly recommend the installation of Anaconda.

2) The anaconda installer strongly recommends the installation without updating the environement variables in the path

3) After the installation of anaconda, Jupyter asks to run in the command line

-> jupyter notebook

which naturally doesn't go because the variables have not been updated in the path.

I just wonder why the Jupyter installation recommendation do not even mention to do that on the website, either by telling that, or by asking to choose the second installation
 way in the Anaconda installation :

Installing Jupyter using Anaconda

We strongly recommend installing Python and Jupyter using the Anaconda Distribution, which includes Python, the Jupyter Notebook, and other commonly used packages for scientific computing and data science.

First, download Anaconda. We recommend downloading Anaconda’s latest Python 3 version.

Second, install the version of Anaconda which you downloaded, following the instructions on the download page.

Congratulations, you have installed Jupyter Notebook! To run the notebook, run the following command at the Terminal (Mac/Linux) or Command Prompt (Windows):

jupyter notebook

Best regards !

Antoine

As far as I rememeber – at least when I installed on macOS – anaconda asked if it could update my env-variable by modyfying my bashrc on its own.

Are you using windows ? It may be that on windows they recommend you to use the Anaconda launcher which will not modify the Env Variable, but shell started from the launcher will have Path setup correctly.

exactly,

i know the problem, and just wonder why Jupyter does not ask neither to choose the install with updating the environment variables or to update the variables path afterwards, but ok...

Best regards,

Antoine

but Now, i know what a solution ( or maybe i did not understand it ) : anaconda comes with anaconda prompt, and from there it's possible to enter "jupyter notebook", and not from the windows cmd.;-)
