This will create a conda environment named dmat with the latest Python 3.6 package ready to go. You should be presented with a list of packages that will be installed, and asked if you wish to proceed. To do so, just enter the character y . If this operation is successful, you should see the following output at the end:

Preparing transaction: done Verifying transaction: done Executing transaction: done # # To activate this environment, use # # $ conda activate dmat # # To deactivate an active environment, use # # $ conda deactivate

As the message suggests, you will need to type the following command to activate and start entering commands within our environment named dmat .

conda activate dmat

Once you do that, you should see your terminal prompt now leads with the environment name within parantheses:

( dmat ) melica:~ shahin$

Note The example above shows the macOS machine name "melica" and the user "shahin". You will see something different on your own machine, and it may appear in a different format on a different operating system such as Windows. As long as the prompt leads with "(dmat)", you are on the right track.
