IndexError: list index out of range

[oliverban]

I get the same error as another user but with different error lines. After "Run 1st Key Frame" which works well, I get my style.
Then running "Run Key Frames" gives:

And then I read something about dividing doing some frame math myself, but I don't know the formula/equation I should use for that.

Did you change the DDIM step? Changing the DDIM step might cause this issue.
Make sure cfg.ddim_steps * cfg.mask_period[0] and cfg.ddim_steps * cfg.mask_period[1] are integers.

In the webUI I might've changed the steps, yes. If there are specific requirements for that and not being able to change it, that should be stated. There seems to be too many settings that should be "hard baked" into the process, removing the sliders (if they aren't created as variables that change the underlying math so it works anyways).

Please reconsider how this is implemented, i.e, maybe make a check for integers and if not, put that out as a error. I do understand this is very new so I hope it can be made more flexible in the future - I'll come back to this one when it is ready!

We have fixed it. We add a constraint to ensure the steps to be a multiple of 20.

Rerender_A_Video/webUI.py

	ddim_steps = gr.Slider(label='Steps',
	minimum=20,
	maximum=100,
	value=20,
	step=20)

Awesome news! :) I'll update ASAP!

[williamyang1991]

We would like to provide more flexible options for users to try. However, this may introduce some unexpected conflict.
Thus, we are actively discovering and solving these issues.

Hope this update will solve your IndexError: list index out of range error

I've changed the maximum of steps = 120 and set the steps = 120 and got the same error. How to "run all" when setting the steps = 120 or more?

[williamyang1991]

@Jerx2y the mask is generated here.

Rerender_A_Video/webUI.py

Lines 540 to 545 in a348e0a

	for i in range(cfg.ddim_steps):
	if i <= cfg.ddim_steps * cfg.mask_period[
	0] or i >= cfg.ddim_steps * cfg.mask_period[1]:
	masks += [None]
	else:
	masks += [mask * cfg.mask_strength]

You can check the length of the mask (len(masks)).
And see whether it is smaller than the total running steps.
