Problem using Anaconda
You can make sure that command is executed for every terminal (meaning Anaconda will be found) by adding it to your user's bash profile.

Open a terminal and follow these steps:


open the terminal profile: gedit ~/.bashrc
at the end of the file, add: export PATH=~/anaconda3/bin:$PATH
save the file (control+s) and close it
load the changed profile: source ~/.bashrc


Now this terminal window (and any new ones) should find Anaconda! See which version of Python is now the default, using which -a python. First in the list should be something like /home/username/anaconda3/bin/python

The Anaconda setup/installation usually asks you if you want to prepend Anaconda to start of your path, so whoever installed it must have said no or skipped that step.
