A local image upscaler using Replicate. Upscale images using a high-resolution controlnet model:

https://replicate.com/batouresearch/high-resolution-controlnet-tile

1. Make a Replicate account and set your token:

   export REPLICATE_API_TOKEN=<token>

1. Install the required packages from requirements.txt using pip:

   pip install -r requirements.txt

2. Make the script upscale executable:

   chmod u+x upscale

3. You can run the script directly using the following command:

   ./upscale path_to_your_image.png

   This will upscale the image at the specified path using the default parameters.

4. Optionally, you can add the script to your PATH to run it from anywhere. To make this change persistent across sessions, add the export command to your shell's configuration file (e.g., ~/.bashrc or ~/.bash_profile for bash, ~/.zshrc for zsh):

   echo 'export PATH=$PATH:/path/to/script/directory' >> ~/.bashrc

   Then, source your shell's configuration file to apply the change immediately:

   source ~/.bashrc

You can also specify additional parameters such as steps, strength, scheduler, guess_mode, resolution, guidance_scale, condition_scale, negative_prompt, and prompt. For example:

./upscale path_to_your_image.png --steps 30 --strength 0.5

This will upscale the image with 30 steps and a strength of 0.5.

The upscaled image will be saved in the same directory as the original image with -upscaled appended to the original file name.
