gnome-terminal: command not found

Followed install instructions but got this error:
```bash
$ bash neural-style-website-up.sh
neural-style-website-up.sh: line 4: gnome-terminal: command not found
```

The script neural-style-website-up.sh is failing because it calls 'gnome-terminal' which is not available on non-GNOME systems. Look at line 4 of that script to see how the terminal is launched. Research cross-platform ways to open a terminal (e.g., detect the OS, use xterm, or offer a fallback). Check if there are any existing scripts or documentation about environment setup.
