When I load this model“sd3_medium_incl_clips_t5xxlfp8.safetensors”, this prompt appears. How to solve it?

i had the same problem. others gave various ways of solving this, but (due to my hardware being older - a 3060) i had to use the base medium model without the t5xxlfp8 included because my machine doesn't have the ability to process the fp8 data

so to solve it, i downloaded the medium model, the clip_l, the clip_g, and the xxlfp16 models from the files section and then used the comfyUI workflow to plug those in. it worked for me.

so the workflow would look like this (with the fp8 version being replaced by the fp16). Again, this is what worked for me. If you have newer hardware there are other solutions likely, but this is the one that was my ultimate solution after trying multiple other things.

Please upgrade your torch to >=2.2 for fp8 support , or try the t5 fp16 version.
