| # SELD233 Spatial Validation |
|
|
| ## Purpose |
| Validate the implemented `audio + spatial + text` path with a synthetic `B=3` |
| FOA batch whose waveform lengths differ per sample. |
|
|
| The validation script prints: |
| - processor outputs and placeholder expansion results |
| - `FOA -> 7ch` feature shapes |
| - SELD backbone hidden-state shapes |
| - `2.5 Hz` spatial-token shapes |
| - the final multimodal token tensor shape implied by the expanded prompt |
|
|
| If the full Qwen model is loaded, it also builds the actual multimodal |
| `inputs_embeds` tensor after audio and spatial injection. |
|
|
| ## Script |
| - [validate_seld233_spatial_random_foa.py](/apdcephfs_cq10/share_1603164/user/schmittzhu/code/spur-qwen-2.5-omni/scripts/validate_seld233_spatial_random_foa.py) |
|
|
| ## Recommended Run |
| Shape-only validation without loading the full Qwen model: |
|
|
| ```bash |
| python scripts/validate_seld233_spatial_random_foa.py \ |
| --model-id /apdcephfs_cq10/share_1603164/user/schmittzhu/model/Qwen2.5-Omni-7B \ |
| --baseline-repo-path /apdcephfs_cq10/share_1603164/user/schmittzhu/code/DCASE2024_seld_baseline \ |
| --seld233-checkpoint-path /apdcephfs_cq10/share_1603164/user/schmittzhu/code/DCASE2024_seld_baseline/3_1_dev_split0_multiaccdoa_foa_model.h5 \ |
| --seld233-feature-stats-dir /apdcephfs_cq10/share_1603164/user/schmittzhu/data/seld_feat_label/starss23_plus_foa_16k_29cls |
| ``` |
|
|
| Full multimodal embedding construction on a single device: |
|
|
| ```bash |
| python scripts/validate_seld233_spatial_random_foa.py \ |
| --model-id /apdcephfs_cq10/share_1603164/user/schmittzhu/model/Qwen2.5-Omni-7B \ |
| --baseline-repo-path /apdcephfs_cq10/share_1603164/user/schmittzhu/code/DCASE2024_seld_baseline \ |
| --seld233-checkpoint-path /apdcephfs_cq10/share_1603164/user/schmittzhu/code/DCASE2024_seld_baseline/3_1_dev_split0_multiaccdoa_foa_model.h5 \ |
| --seld233-feature-stats-dir /apdcephfs_cq10/share_1603164/user/schmittzhu/data/seld_feat_label/starss23_plus_foa_16k_29cls \ |
| --load-qwen-model \ |
| --device cuda:0 \ |
| --dtype bfloat16 |
| ``` |
|
|
| ## Expected Core Shapes |
| For 20-second padded inputs: |
| - `spatial_audio`: `[B, 320000, 4]` |
| - `features`: `[B, 7, 1000, 64]` |
| - `hidden_states`: `[B, 200, 128]` |
| - `spatial_tokens`: `[B, T_spat_max, 256]` |
|
|
| `T_spat_max` depends on the longest valid sample in the batch. |
|
|
| ## Current Limits |
| - `use_audio_in_video=False` only |
| - `image + spatial` not implemented |
| - `return_audio=True` not implemented for the spatial subclass |
