I am experiencing the same error, seems like there is an issue when unloading the motion module. Restarting the whole webui.bat allows for one successful generation, afterwards I'm getting weird noise unless I restart the webui.bat.

yes. this is annoying. For me my generation doesn't even make a gif.

Please give me a screenshot of your webui, otherwise I cannot reproduce your error on my side.

Hello, I'm not the OP but I have the same error. The Webui is up-to-date and I installed this addon about 30 minutes ago so I assume this is as well. I have included a screenshot, hope it helps.

Yep same error and same symptoms with all images going to garbage after first run.

I fixed it by reinstalling torch. Check for error messages on the window where you launched webui

For old pytorch there is a solution:

def _pop(self, key):
    v = self[key]
    del self[key]
    return v

def _insert(self, index, module):
    n = len(self._modules)
    if not (-n <= index <= n):
        raise IndexError(
            f'Index out of range: {index}')
    if index < 0:
        index += n
    for i in range(n, index, -1):
        self._modules[str(i)] = self._modules[str(i - 1)]
    self._modules[str(index)] = module
    return self

TimestepEmbedSequential.pop = _pop
TimestepEmbedSequential.insert = _insert

in scripts/animatediff.py somewhere after imports
But it only works for 1 run

I will close this issue for now. If you meet this problem again, please update your pytorch by running webui with --reinstall-torch (if I remember correctly)
