failing to run bash scripts/test_training.sh at the end of installation

[Natotela]

win10, conda, had to enable virtualization, wsl, and to install ubuntu as a distro merely to have the bash command.
Now I get a:
(imaginaire) F:\Progz\imaginaire>bash scripts/test_training.sh
scripts/test_training.sh: line 2: syntax error near unexpected token $'{\r'' 'cripts/test_training.sh: line 2: function output {

and I'm too exhausted to figure out this one. Wish there was a quick SH to BAT converter. I did use the install.bat, wasn't sure about VI/M editor popping up in the midst of the install.sh.
