Hey there,

when lunching my webui cmd, the program is always relaunching. there is an runtime error

RuntimeError: CUDA out of memory. Tried to allocate 114.00 MiB (GPU 0; 2.00 GiB total capacity; 1.67 GiB already allocated; 0 bytes free; 1.72 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

what does that mean? what have i to do? how can i config the memory?  
greetings.
