You can use Google Colab to apply ESRGAN on your own images. Also high model compatibility because "old-arch" and "new-arch" models should work.

Original Colab file created by shahidul56 can be found here and here. This notebook is a modification by styler00dollar.

Also thanks to ata4 for creating esrgan-launcher and Joey for further improving that repo.

Important information

• If you can't open Colab-ESRGAN.ipynb inside your Google Drive, try this colab link and save it to your Google Drive. The "open in Colab"-button can be missing in Google Drive, if that person never used Colab.
• ESRGAN tutorials and custom models can be found in this wiki page.
• Google Colab does assign a random GPU. It depends on luck.
• The Google Colab VM does have a maximum session length of 12 hours. Additionally there is a 30 minute timeout if you leave colab. The VM will be deleted after these timeouts.
