I'm able to make it works on my GTX 1650 LP. Had to use full precision though or else it generates green images. I also had to reduce the resolution to 320x320 and close every applications that uses vram because the GPU only has 4GB of vram. Took about 2 minutes to generate a single image with ddim sampling steps set to 50.
