Hi, could you share the output of diffusers-cli env and the exact code you're using, so that we can try to reproduce the error

Using the official Diffusers documentation code + Para-attn FB Cache . Do we have quantized versions in diffusers that support FB Cache?

[a-r-r-o-w]

There's no official checkpoint maintained by us that is quantized. Users are expected to quantize models on their own (documentation). Diffusers support for FBCache is being implemented here: #11180
