WSL support

[rakuri255]

BTW, I wouldn't mind to try the WSL solution, but I don't know how to follow after running the command:

sudo apt update && sudo apt install nvidia-cuda-toolkit

Because following the tutorial makes this issue:

/mnt/c/Programas/UltraSinger-WSL$ .venv\Scripts\activate
.venvScriptsactivate: command not found
/mnt/c/Programas/UltraSinger-WSL$ cd .venv
/mnt/c/Programas/UltraSinger-WSL/.venv$ ls -a
.  ..  bin  include  lib  lib64  pyvenv.cfg
/mnt/c/Programas/UltraSinger-WSL/.venv$ cd Scripts
-bash: cd: Scripts: No such file or directory

I imagine that the instructions for using python on linux would be different, but I never used so I don't know how to proceed.

Ok, after a lot of try and error, just found the way to use in WSL. However, since I have to try and install a lot of things, I don't remember the full steps, but here I'll write some of them at least.

Some previous steps (not all the necessary previous steps unfortunately):

Installing python venv:
sudo apt-get install python3-venv

Setting up the venv:
python3 -m venv .venv

Installing ffmpeg on WSL (thanks to https://gist.github.com/ScottJWalter/eab4f534fa2fc9eb51278768fd229d70)

sudo add-apt-repository ppa:mc3man/trusty-media
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install ffmpeg

For using:

source .venv/bin/activate
cd src
python3 UltraSinger.py <commands>

For gpu you need sudo apt install nvidia-cuda-toolkit
