Conda 4.3.24 + Jupyter 4.3.0 + Python 2.7 on Windows 7: Jupyter + Conda ipython kernel integration does not work

[Paul Mayer]

Hi,

I am currently trying to get a Jupyter Notebook Environment running with Python 2.7 and have this question also to the Jupyter mailing list, as I am not sure wherein the problem might lie.

Using conda, I have installed ipykernel (4.6.1), nb_conda_kernels (2.1.0), jupyter (4.3.0) and Python 2.7 in a new environment.

Launching "jupyter notebook", the tab "Conda" shows all my conda environments. However, if I try to create a new Notebook, it only shows "Python 3" as kernel (which does not exist and I have no idea where it is coming from).

Trying to create the notebook, the following warning is logged:

[W 13:36:55.585 NotebookApp] Kernel not found: python3

Running jupyter kernelspec list gives the following:

Available kernels:

  python2    C:\x\y\z\jupyter\kernels\python2

The kernel.json in the folder contains:

{

 "display_name": "Python 2", 

 "language": "python", 

 "argv": [

  "python", 

  "-m", 

  "ipykernel_launcher", 

  "-f", 

  "{connection_file}"

 ]

}

Which should be fine given the %PATH% is set appropriately.

Is there anyone else who has problems with conda's ipython kernel integration in Jupyter? Is there anything else I need or does anyone have any recommendations regarding what I could look into?

Thanks,

Paul
