I am installing pytorch with pip3. I am using the commands from the website:
pip3 install http://download.pytorch.org/whl/cu90/torch-0.3.0.post4-cp35-cp35m-linux_x86_64.whl
pip3 install torchvision

The first one works perfectly and installs pytorch. The second one, however, gives:

You are using pip version 8.1.1, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

The problem is I do not want to use anaconda, I just want a regular pip3 installation. I remember stumbling across this error some time ago, and I somehow managed to overcome it, but I really don’t remember how.
