AttributeError in `diffusers.models.transformers.transformer_flux` - Missing `rope` Attribute

[rajveer43]

Describe the bug

I encountered an issue while working with the diffusers library where an AttributeError is raised because the transformer_flux module does not have an attribute named rope. This problem arises when trying to modify therope function to handle CUDA devices.

Reproduction

Below is a code snippet that leads to this error:

import torch
from diffusers import FluxPipeline
import diffusers
from PIL import Image
import matplotlib.pyplot as plt

# Attempt to modify the rope function to handle CUDA device
_flux_rope = diffusers.models.transformers.transformer_flux.rope
def new_flux_rope(pos: torch.Tensor, dim: int, theta: int) -> torch.Tensor:
    assert dim % 2 == 0, "The dimension must be even."
    if pos.device.type == "cuda":
        # Move tensor to CPU for ROPE computation, then move it back to CUDA
        return _flux_rope(pos.to("cpu"), dim, theta).to(device=pos.device)
    else:
        # Perform ROPE computation directly if tensor is not on CUDA
        return _flux_rope(pos, dim, theta)

# Replace the original rope function with the new one
diffusers.models.transformers.transformer_flux.rope = new_flux_rope

The rope function should be accessible in the transformer_flux module to allow customization, such as handling CUDA devices or modifying ROPE computations.

hi @rajveer43 we did a refactor and replaced the rope method with the get_1d_rotary_pos_embed see this PR https://github.com/huggingface/diffusers/pull/9074
