Cannot find module _C.pyd

Hi, when I'm using the Dreamboth LoRA, the command line shows the next error:

enable LoRA for U-Net prepare optimizer, data loader etc. use AdamW optimizer | {} running training / 学習開始 num train images * repeats / 学習画像の数×繰り返し回数: 2000 num reg images / 正則化画像の数: 0 num batches per epoch / 1epochのバッチ数: 1000 num epochs / epoch数: 1 batch size per device / バッチサイズ: 2 gradient accumulation steps / 勾配を合計するステップ数 = 1 total optimization steps / 学習ステップ数: 1000 steps: 0%| | 0/1000 [00:00<?, ?it/s]epoch 1/1 Could not find module 'E:\IA\Plugins\Kohya\kohya_ss\venv\Lib\site-packages\xformers_C.pyd' (or one of its dependencies).

The file exists in the specified location. Anyone has any idea what the problem is?

Before this error I had other related with libbitsandbytes_cuda116.dll. I solved it like it specifies in this issue: https://github.com/TimDettmers/bitsandbytes/issues/161 Thanks you

I have the same question. Did you have ever solved it yet?

The installation of xformers seems to be something wrong. Please uninstall with pip uninstall xformers and try to install again with pip install -U -I --no-deps https://github.com/C43H66N12O12S2/stable-diffusion-webui/releases/download/f/xformers-0.0.14.dev0-cp310-cp310-win_amd64.whl.

Having this same issue, your solution above did not fix it

I had the same problem and fixed it by deleting the python_embeded folder then extracting a new python_embeded folder from the comfyui prortable install to the old location and it worked again
