ComfyUI utan dator
Inget grafikkort? BitVector kör samma modeller med öppen källkod och ComfyUI-arbetsflöden i molnet, från telefonen, surfplattan eller vilken PC som helst. Förinstallerat, ingen installation, fast pris.
CLIP Text Encode (Prompt)
- Token indices sequence length is longer than the specified maximum (77)
- The prompt seems ignored and the image barely changes
- Error: embedding not found / "embedding:xyz" printed in the output
- Weighted words like (red:1.5) produce artifacts
ComfyUI Manager
- Red nodes remain after installing missing nodes
- IMPORT FAILED for a pack
- Manager button missing
- Update All broke everything
- This action is not allowed with this security level
KSampler
- Noise, static or a blurry blob instead of an image
- Deep-fried, oversaturated, high-contrast output
- torch.OutOfMemoryError: CUDA out of memory during sampling
- Error: mat1 and mat2 shapes cannot be multiplied
- Images change every run although the seed is fixed
- The same image repeats across prompts (seed stuck)
Load Checkpoint
- ckpt_name shows "undefined" or the dropdown is empty
- Error while deserializing header: HeaderTooLarge or MetadataIncompleteBuffer
- Images come out as noise or grey squares with a valid checkpoint
- Clip missing: ["text_projection.weight"] or "clip missing" warnings in the console
- Out of memory as soon as the checkpoint loads
Save Image
- Images are not in the output folder
- PermissionError when saving
- Dragging the PNG into ComfyUI does not restore the workflow
- Colours are washed out compared with the preview
VAE Decode
- Black image after decode
- Given groups=1, weight of size [...] expected input to have 4 channels, but got 16
- Out of memory in VAE Decode
- Visible grid seams in the decoded image
