jupyter 다중 커널(kernel) 설치하기

$ jupyter kernelspec install-self

[InstallNativeKernelSpec] Installed kernelspec python2 in /usr/local/share/jupyter/kernels/python2

Optional: Installing Kernels

설치된 jupyter 커널 확인

$ jupyter kernelspec list

Available kernels:

  python3    /Users/{USER}/Library/Jupyter/kernels/python3

  python2    /usr/local/share/jupyter/kernels/python2

$ jupyter kernelspec remove python3

$ jupyter kernelspec list

Available kernels:

  python3    /usr/local/lib/python3.5/site-packages/ipykernel/resources

  python2    /usr/local/share/jupyter/kernels/python2

https://ipython.readthedocs.io/en/latest/install/kernel_install.html

Kernels for Python 2 and 3

$ conda create -n python3 python=3 ipykernel

=> 이렇게만 했는데, jupyter notebook 에 Python [python3] 커널이 자동으로 추가되었음. (2016-08-07)

$ conda create -n tf3 python=3 anaconda   (tf3 라는 이름으로 라이브러리 환경을 생성함)

$ source activate tf3    (Windows 에서는 source 명령을 치지 않음)

$ conda install -c conda-forge tensorflow   (Anaconda 에서 tensorflow 설치)

jupyter notebook 을 띄우면 Python [conda env:tf3] 이 자동으로 추가된 것을 볼 수 있다. (2016-10-23)

Anaconda를 사용하지 않고 Jupyter notebook Kernel에 추가하는 법

$ python -m ipykernel install --user

Installed kernelspec python3 in /Users/{USER}/Library/Jupyter/kernels/python3

$ jupyter kernelspec list

Available kernels:

  python3    /Users/{USER}/Library/Jupyter/kernels/python3

  python2    /usr/local/share/jupyter/kernels/python2

$ pip install watermark

Collecting watermark

Requirement already satisfied (use --upgrade to upgrade): ipython in /Users/{USER}/anaconda/envs/python3/lib/python3.5/site-packages (from watermark)

Installing collected packages: watermark
