Floating point exception (core dumped)?

[buptmengjj]

When I used TeaCache to accerate the model of FLUX1.dev，the error "Float point exception (core dumped)" occured. How to solve it? The Inference code are " FluxTransformer2DModel.forward = teacache_forward num_inference_steps = 4 seed = 1997 guidance_scale = 0.0 height = 720 width = 1280 prompt = "An image of a squirrel in Picasso style" pipeline = DiffusionPipeline.from_pretrained("/workspace/mengjj/models/AIGC/FLUX.1-schnell", torch_dtype=torch.float16)

pipeline = DiffusionPipeline.from_pretrained("/workspace/mengjj/models/FLUX.1-dev", torch_dtype=torch.float16)

pipeline.enable_model_cpu_offload() #save some VRAM by offloading the model to CPU. Remove this if you have enough GPU power

TeaCache
