4 months ago After investigating a little the file latent_preview.py, function decode_latent_to_preview, which was modified a few days ago, the values are transformed into [0.0, 255.0], but the dtype stays torch.float32 instead of becoming torch.uint8.
For some reason the "to" method doesn't do the type change unless you do it alone like this:
latents_ubyte = (((latent_image + 1) / 2)
.clamp(0, 1) # change scale from -1..1 to 0..1
.mul(0xFF) # to 0..255
)
latents_ubyte = latents_ubyte.to(dtype=torch.uint8)
latents_ubyte = latents_ubyte.to(device="cpu", dtype=torch.uint8, non_blocking=True)Not sure if it doesn't beat the purpose though. Hope it helps.

Hi,
After 2 days without using, I updated comfyUI and now I get this error when I try to sample anything, seemingly happens when it tries to show a preview:
!!! Exception during processing!!! Cannot handle this data type: (1, 1, 3), <f4 Traceback (most recent call last): File "C:\Users\maveyyl\AppData\Roaming\StabilityMatrix\Packages\ComfyUI\venv\lib\site-packages\PIL\Image.py", line 3130, in fromarray mode, rawmode = _fromarray_typemap[typekey] KeyError: ((1, 1, 3), '<f4')
The above exception was the direct cause of the following exception:
