Ubuntu18 and Mate19 have python 2.7 and python 3.7 running, but python 2.7 is the default.

the install directions need to include (for Ubuntu18 & Mate19)

sudo apt-get install python3-pip
cd ~/HD-BET
pip3 install -e .

the directions as written use pip (which defaults to python 2.7 in ubuntu and generates a "there is no python3.5 or greater" error when trying to install HD-BET)

which then prompts one to one either try and alias out the python2.7 in ubuntu, which works poorly...or uninstall python 2.7, and for ubuntu, that leads to a truly epic fail/disaster.

existing install directions are TOO GENERAL...need to be more specific as stated above if the install is to work smoothlyfor Ubuntu18 or MATE19

Hi,
I will add a notification that users should also try pip3 if they run into problems. This should however not be the default recommendation, because what pip points to depends on your system. For me and many others, pip is python3 as it should be (Python2 is end of life).
Best,
Fabian

Hi Scott,
pip is really the best and easiest tool to install anything in python. I am surprised that you have so many problems.
My recommendation is to create a virtual environment. On Ubuntu this is really easy:

virtualenv -p python3 my_venv # creates a folder my_venv with the virtual environment files
source my_venv/bin/activate # activates the virtual environment. You nee to do this every time you intend to run hd-bet
pip install --upgrade pip # this will update pip and it won't complain anymore. And yes it's pip, not pip3. The virtual environment will make it point to the correct one
# now proceed to install hd-bet from here

Best,
Fabian
