xformers Not working. "torch.cuda.OutOfMemoryError: CUDA out of memory."

[Krazy4Stable]

Hi, I am facing this issue with stable diffusion with I am trying to Hires. fix my image.

torch.cuda.OutOfMemoryError: CUDA out of memory. Tried to allocate 1.77 GiB (GPU 0; 8.00 GiB total capacity; 4.86 GiB already allocated; 0 bytes free; 6.75 GiB reserved in total by PyTorch) If reserved memory is >> allocated memory try setting max_split_size_mb to avoid fragmentation. See documentation for Memory Management and PYTORCH_CUDA_ALLOC_CONF

I have edited the webui-user.bat:
git pull
@echo off

start chrome "http://127.0.0.1:7860/"

set PYTHON=
set GIT=
set VENV_DIR=
set COMMANDLINE_ARGS= --xformers

call webui.bat

I have also updated launch.py:
commandline_args = os.environ.get('COMMANDLINE_ARGS', "--xformers")
