pipe.scheduler.sigmas change after forward call #7904
Description
Describe the bug
I noticed this issue when trying to manually modify the sigmas in my pipeline scheduler. Despite changing the values in this tensor, the sigmas tensor shrinks to the number of inference steps after one inference instance. Subsequent calls no longer change the values of the sigmas.
Reproduction
pipe.scheduler.sigmas = pipe.scheduler.sigmas * 4 # manually modifying sigmas
_ = pipe(..., num_inference_steps = N)
print(pipe.scheduler.sigmas) # len is N + 1, values do not reflect the manual modifications and no longer change in subsequent calls
