FLUX.1-dev

like 4.49k

same on Windows 11
I had to downgrade to numpy <2 and then got this error TypeError: expected str, bytes or os.PathLike object, not NoneType
with this small code example:

from diffusers import FluxPipeline
from huggingface_hub import login

login(token="xxxx")

pipe = FluxPipeline.from_pretrained("black-forest-labs/FLUX.1-dev", torch_dtype=torch.bfloat16)
# pipe.enable_model_cpu_offload() # save some VRAM by offloading the model to CPU. Remove this if you have enough GPU power

prompt = "A cat holding a sign that says hello world"
image = pipe(
    prompt,
    height=1024,        # 1024
    width=1024,         # 1024
    guidance_scale=3.5,
    num_inference_steps=50,
    max_sequence_length=512,
    generator=torch.Generator("cpu").manual_seed(0)
).images[0]
image.save("flux-dev.png")```

did you find a fix?

i think cuda 11 was the issu for me, i went cuda 12 and its working now
