 define the path to the corresponding cross attention
processor. This is strongly recommended when setting trainable attention processors.    Sets the attention processor to use to compute attention.  set_default_attn_processor  < source > ( )    Disables custom attention processors and sets the default attention implementation.  unfuse_qkv_projections  < source > ( )    Disables the fused QKV projection if enabled. This API is 🧪 experimental.
