From b63d0726cd26aa8124e6d2e6f339b474a1563459 Mon Sep 17 00:00:00 2001 From: AUTOMATIC <16777216c@gmail.com> Date: Mon, 22 Aug 2022 20:08:32 +0300 Subject: [PATCH] fixed bug with images not resizing for img2img added GFPGAN as an option for img2img added GFPGAN as a tab added autodetection for row counts for grids, enabled by default removed Fixed Code sampling because no one can figure out what it does; maybe someone will be upset by removal and will tell me --- webui.py | 178 ++++++++++++++++++++++++++++++------------------------- 1 file changed, 98 insertions(+), 80 deletions(-) diff --git a/webui.py b/webui.py index b0d67f316..bb53e5fff 100644 --- a/webui.py +++ b/webui.py @@ -13,6 +13,7 @@ from torch import autocast from contextlib import contextmanager, nullcontext import mimetypes import random +import math import k_diffusion as K from ldm.util import instantiate_from_config @@ -31,7 +32,7 @@ parser = argparse.ArgumentParser() parser.add_argument("--outdir", type=str, nargs="?", help="dir to write results to", default=None) parser.add_argument("--skip_grid", action='store_true', help="do not save a grid, only individual samples.
