Issue resolved by changing version from v0.0.13 in requirements.txt to v0.0.12 as per: AUTOMATIC1111/stable-diffusion-webui#2047

Now another error comes:

can you pl help in understanding cuda & python version that needs to be installed, im using win 11, facing same issue as you mentioned

[VictorLaskin]

You need to put large disclaimer that windows is unsupported if it is so - so people would not waste their time trying to run it on win 11, please. As I see - motion-vector-extractor - is linux only.

[VictorLaskin]

I managed to run it under win11 - 1) in requirements - xformers==0.0.16 and comment out motion-vector-extractor and triton
2) used slightly different version torch - pip install torch==1.13.1+cu117 torchvision==0.14.1+cu117 torchaudio==0.13.1 --extra-index-url https://download.pytorch.org/whl/cu117
3) reinstalled pip install flash-attn==0.2.1 -i https://pypi.tuna.tsinghua.edu.cn/simple - not sure that it's necessity
4) changed backend to gloo in i2vgen-xl\tools\inferences\inference_i2vgen_entrance.py(line 82): dist.init_process_group(backend='gloo', world_size=cfg.world_size, rank=cfg.rank)

and it's generating videos while producing some errors like - 'rm' is not recognized as an internal or external command,
operable program or batch file.
'rm' is not recognized as an internal or external command,

@VictorLaskin Has anyone tried to run this using WSL?..

[leomaxwell973]

To resolve the "rm" errors, you can use either Visual Studio(maybe coder too), or Notepad++, and do a folder or project wide replace command using the advanced find functions in each (ctrl+shift+f in VS, ctrl+f in ++):

Find:
rm -rf
Replace:
RD /S /Q

This should translate the unix command to win equivalent so it can perform it's function in a windows environment.

there is always some risk when doing a mass blind multi file line replace batch job, however, "rm -rf" is rather specific so the risk is low IMO, but, you still own your risk and do so at your own risk.

I believe mine said the project had a total of 17 occurrences. no idea where, so, if you knew where though it's not totally undoable manually as well. or you could search for them instead of replace as well, just slower.

Make sure you are using python3.8 for installing xformers.
