      CogView4 (supports different length c and uc) (#10649) · d90cd362

      * init
      
      * encode with glm
      
      * draft schedule
      
      * feat(scheduler): Add CogView scheduler implementation
      
      * feat(embeddings): add CogView 2D rotary positional embedding
      
      * 1
      
      * Update pipeline_cogview4.py
      
      * fix the timestep init and sigma

      * fix
      
      * [WIP][cogview4]: implement initial CogView4 pipeline
      
      Implement the basic CogView4 pipeline structure with the following changes:
      - Add CogView4 pipeline implementation
      - Implement DDIM scheduler for CogView4
      - Add CogView3Plus transformer architecture
      - Update embedding models
      
      Current limitations:
      - CFG implementation uses padding for sequence length alignment
      - Need to verify transformer inference alignment with Megatron
      
      TODO:
      - Consider separate forward passes for condition/uncondition
        instead of padding approach
      
      * [WIP][cogview4][refactor]: Split condition/uncondition forward pass in CogView4 pipeline
      
      Split the forward pass for conditional and unconditional predictions in the CogView4 pipeline to match the original implementation. The noise prediction is now done separately for each case before combining them for guidance. However, the results still need improvement.
      
      This is a work in progress as the generated images are not yet matching expected quality.

      * remove text_projector

      * [WIP] for older glm
      
      * use with cogview4 transformers forward twice of u and uc
      
      * Update convert_cogview4_to_diffusers.py
      
      * remove this
      
      * use main example
      
      * change back

      * setback
      
      * back
      
      * back 4
      
      * Fix qkv conversion logic for CogView4 to Diffusers format
      
      * back5
      
      * revert to sat to cogview4 version
      
      * update a new convert from megatron
      
      * [WIP][cogview4]: implement CogView4 attention processor
      
      Add CogView4AttnProcessor class for implementing scaled dot-product attention
      with rotary embeddings for the CogVideoX model. This processor concatenates
      encoder and hidden states, applies QKV projections and RoPE, but does not
      include spatial normalization.
      
      TODO:
      - Fix incorrect QKV projection weights
      - Resolve ~25% error in RoPE implementation compared to Megatron
      
      * [cogview4] implement CogView4 transformer block
      
      Implement CogView4 transformer block following the Megatron architecture:
      - Add multi-modulate and multi-gate mechanisms for adaptive layer normalization
      - Implement dual-stream attention with encoder-decoder structure
      - Add feed-forward network with GELU activation
      - Support rotary position embeddings for image tokens
      
      The implementation follows the original CogView4 architecture while adapting
      it to work within the diffusers framework.
      
      * with new attn
      
      * [bugfix] fix dimension mismatch in CogView4 attention
      
      * [cogview4][WIP]: update final normalization in CogView4 transformer
      
      Refactored the final normalization layer in CogView4 transformer to use separate layernorm and AdaLN operations instead of combined AdaLayerNormContinuous. This matches the original implementation but needs validation.
      
      Needs verification against reference implementation.
      
      * 1
      
      * put back
      
      * Update transformer_cogview4.py
      
      * change time_shift
      
      * Update pipeline_cogview4.py
      
      * change timesteps
      
      * fix
      
      * change text_encoder_id
      
      * [cogview4][rope] align RoPE implementation with Megatron
      
      - Implement apply_rope method in attention processor to match Megatron's implementation
      - Update position embeddings to ensure compatibility with Megatron-style rotary embeddings
      - Ensure consistent rotary position encoding across attention layers
      
      This change improves compatibility with Megatron-based models and provides
      better alignment with the original implementation's positional encoding approach.
      
      * [cogview4][bugfix] apply silu activation to time embeddings in CogView4
      
      Applied silu activation to time embeddings before splitting into conditional
      and unconditional parts in CogView4Transformer2DModel. This matches the
      original implementation and helps ensure correct time conditioning behavior.
      
      * [cogview4][chore] clean up pipeline code
      
      - Remove commented out code and debug statements
      - Remove unused retrieve_timesteps function
      - Clean up code formatting and documentation
      
      This commit focuses on code cleanup in the CogView4 pipeline implementation, removing unnecessary commented code and improving readability without changing functionality.
      
      * [cogview4][scheduler] Implement CogView4 scheduler and pipeline
