SR scale x1 with OOM: CUDA out of memory

[amanoooo]

I want to handle my photo(resolution 4080 × 3060), using RTX 4090, enabled Tiled, it failed!

What should i do? Does DiffBIR support quantization ?

Hey, try tiled options for inference. It can avoid memory limitation.

If you wanna inference large-resolution images with limited memory, try to specify --tiled related params as follows.

python inference.py \
.... \
--tiled --tile_size 512 --tile_stride 256

@ziyannchen 请问 tiled sample 是否意味着对图像分片超分？例如一张图像是1024x1024，tile_stride=256，那么就会把图像分成四份，对每份进行超分，然后拼接？
