er will be used for computing the prompt embeddings.    Encodes the prompt into text encoder hidden states.  fuse_qkv_projections  < source > ( unet: bool = True vae: bool = True  )   Parameters   unet (bool, defaults to True) — To apply fusion on the UNet.   vae (bool, defaults to True) — To apply fusion on the VAE.    Enables fused QKV projections. For self-attention modules, all projection matrices (i.e., query,
key, value) are fused. For cr
