Jupyter Notebook doesn't show new environments

问题

I have anaconda python 2.7 installed on my windows and I recently created a new environment for python 3.5 (using conda create -n py35 python=3.5).

When I activate py35 and run jupyter notebook, it doesn't show py35 environment. It only has python root (py27).

How can I use this environment by jupyter ?

回答1:

To use jupyter notebook inside a virtual environment, ipykernal is required to be installed in your venv.

1. Inside your virtual environment:

   pip install ipykernel

2. Then run the kernel "self-install" script:

   python -m ipykernel install --user --name=my-virtualenv-name

Now, your new kernel has been installed.

See: pythonanywhere

You can install nb_conda and it will give you Conda environment and package access extension from within Jupyter. Inside your env you can use this command:

conda install nb_conda
