Tuning:

Inference:
python evaluate/cogvideo_example.py --use_spas_sage_attn --model_out_path evaluate/models_dict/CogVideoX-2b_0.06_0.07.pt
Note: We provide pre-tuned hyper-parameters
CogVideoX-2b_0.06_0.07.pt
that allow you to run the inference script directly. However, for better performance in both speed and quality, we recommend re-tuning because the provided hyper-parameters are tuned with SpargeAttn based on SageAttention, whereas the default API is based on SageAttention2 now.
The tuning and inference usage is similar to CogVideoX.
Note: All experiments in this paper used SpargeAttn based on SageAttention. An updated implementation based on SageAttention2, is available now. It further offers a 30% speedup.
