For local use, you need to disable the prompt optimization node. --- ### ⚠️ Torch Compile Warning If your setup doesn’t support torch compile, set attention mode to `sdpa` in the model loader and bypas the Torch Compile settings and adjust the base_precision to just fp16 --- ### ⚠️ Block Swapping Block swapping helps if you have lower VRAM and/or get OOM. You can bypass it first and then update the blocks to swap to a higher number till you don't get OOM (up to 40) It will run slower so don't use if you have enough VRAM. --- ### ⚠️ Other known issues If you get an error that has "FlowMatch" in it, please change your scheduler to uni_pc from FlowMatch_Causvid (or something else you like, dmp++_sde/beta is good too)
