After installing anaconda - command not found: jupyter

Add $HOME/anaconda3/bin to your $PATH and jupyter-notebook should work. There are a ton of other binaries you can lookup in that folder as well.

export PATH=$HOME/anaconda3/bin:$PATH

then

jupyter-notebook

You need to activate your conda environment (source bin/activate) and then do

$ pip install jupyter # Alternatively, you can do `conda install jupyter`
$ jupyter notebook # to actually run the notebook server
