### Inference a video using streaming mode (Experimental features)
We implement an experimental streaming mode **without training**. In details, we save the hidden states of temporal attentions for each frames in the caches, and only send a single frame into our video depth model during inference by reusing these past hidden states in temporal attentions. We hack our pipeline to align the original inference setting in the offline mode. Due to the inevitable gap between training and testing, we observe a **performance drop** between the streaming model and the offline model (e.g. the `d1` of ScanNet drops from `0.926` to `0.836`). Finetuning the model in the streaming mode will greatly improve the performance. We leave it for future work.
