 - **Some Notes** 
 
     Ideally, you can prepare these cache data from `.npy` files (as did in VidVRD). However, due to some ancient coding reasons, we extract bbox RoI feature for each frame, which makes these `.npy` files too large (**827G** for VidOR-train and **90G** for VidOR-val). Therefore, we only release pre-prepared cache data as above.
