Instructions to setup your virtual environment using pyenv on Debian/Ubuntu:

1. Install the necessary changes with this command:
    sudo apt install -y make build-essential libssl-dev zlib1g-dev \
    libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev \
    libncursesw5-dev xz-utils tk-dev libffi-dev liblzma-dev python-openssl \
    git

2. Install pyenv:
    git clone https://github.com/pyenv/pyenv.git ~/.pyenv

3. Add the pyenv to your $PATH (if you use a different shell than bash you have to change ~/.bashrc accordingly):
    echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc
    echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrc
    echo 'eval "$(pyenv init --path)"' >> ~/.bashrc

4. Install Python Version 3.10.9:
    pyenv install 3.10.9

5. Clone this repository:
    git clone https://github.com/GeorgiosIoannouCoder/realesrgan.git

6. Navigate to the cloned repository folder:
    cd realesrgan

7. Use the installed Python version in the cloned repository folder:
    pyenv local 3.10.9

8. Create virtual environment in the cloned repository folder:
    python -m venv .realesrgan-venv

9. Activate the virtual environment:
    source .realesrgan-venv/bin/activate

10. Install the dependencies listed in the requirements.txt file:
    pip install -r requirements.txt
