Eris Bot API modifier
Eris Promptlog:
Every Prompt that is send from through the API will be saved in a Textfile, with the current date as name, in a folder named "logs"
Eris Imagelog:
Every generated Images will be saved in the default "outputs" folder
Eris Consolelog:
Every Prompt that is send from through the API will be displayed in the console/terminal window
Eris TRTpatch:
Necessary modification for the TRT Plugin to work.
Please refer the Readme on https://git.foxo.me/Hitmare/Eris_api_tensor_patch for the full TRTpatch instructions
2023-11-14 19:46:55 +00:00
Eris Imagelimit:
Will resize every request down to 1024px max on height and width, keeping the aspect ratio. Also reduces Steps down to the set limit if the set Steps exceeds the limit
Compatible with the TRTpatch. Please refer the Readme on https://git.foxo.me/Hitmare/Eris_api_tensor_patch for the full TRTpatch instructions
2023-11-14 19:46:55 +00:00
