| ### Using mock data (optional, for debugging) | ||
|
|
||
| - Using `--mock` argument. | ||
| - Adjust `video_size` (F_latents, H_latents, W_latents) and `number_packed_samples` of `WanMockDataModuleConfig` in `wan.py`. Total `seq_len = F * H * W * number_packed_samples`. |

Can you help update this seq_len = F * H * W * number_packed_samples to seq_len = (F_latents // patch_temporal) * (H_latents // patch_temporal) * (W_latents // patch_temporal) * number_packed_samples

| - Please use the appropriate system config recipe in `examples/megatron/recipes/wan/conf/<h100/gb200/gb300>_perf_pretrain_mock.yaml` | ||
| - Usage example `examples/megatron/recipes/wan/pretrain_wan.py --mock --training-mode pretrain --config-file examples/megatron/recipes/wan/conf/gb300_perf_pretrain_mock.yaml` | ||
| - Note that the FLOPs calculation for Wan 2.1 is not currently supported in Megatron-Bridge. Please use a manual calculator until a fix is made. |

Can we share some of our pre-computed FLOPs here, as a reference point for users? It's not trivial calculating the correct FLOPs number.
