Deleting everything Python related is a bad idea. There are system files which require it. Hopefully you didn't delete the wrong files and won't have to reinstall your operating system.
Regarding your question, you need to first activate your conda environment before launching jupyter notebook.
To see which environment you already have installed, type the following from a terminal window:
conda info --envs
Then type the following to activate your environment (obviously my_env
is the name of what ever your environment is).
source activate my_env
From here, you are in your conda environment. To open Jupyter notebook, just type:
jupyter notebook
This notebook will be linked to your conda environment and will have access to all modules therein (type conda list
from the terminal once you've activated your environment per above to see them, or !conda list
from within the notebook).
Just for fun, we'll create a quick environment named test_env.
conda create -n test_env pandas jupyter notebook qtconsole matplotlib
source activate test_env
jupyter notebook # launches your notebook
Alternatively, to launch qtconsole:
jupyter qtconsole
Although we only installed a few packages, all linked dependencies are also installed (including numpy). This is now the output of conda list
:
