ables fused QKV projections. For self-attention modules, all projection matrices (i.e., query,
key, value) are fused. For cross-attention modules, key and value projection matrices are fused. This API is 🧪 experimental.  get_guidance_scale_embedding  < source > ( w embedding_dim = 512 dtype = torch.float32  ) → torch.FloatTensor  Parameters   timesteps (torch.Tensor) —
