Anaconda Environment Doesnt activate

Question

So i installed an Anaconda environment according to

conda create -n tardis --file https://raw.githubusercontent.com/tardis-sn/tardis/master/pip-requirements python=2 pip

Now I am trying to activate the environment using source activate tardis

But it's giving me the following error

pfrcks@pfrcks~ $ source activate tardis Reading package lists... Done Building dependency tree
Reading state information... Done E: Unable to find a source package for activate

Any help ??
