 We provide two implementation instances of SQR-adamixer in this repo, one is in [/mmdet/models/roi_heads/adamixer_decoder_Qrecycle.py](/mmdet/models/roi_heads/adamixer_decoder_Qrecycle.py), which might be slower for training but require less GPU memory (and easy to understand the logic). Another is in [/mmdet/models/roi_heads/adamixer_decoder_Qrecycle_optimize.py](/mmdet/models/roi_heads/adamixer_decoder_Qrecycle_optimize.py), which is much faster than the former but has higher requirement on GPU memory. 
 
 ### SQR-Deformable DETR
-We provide the implementation of SQR-deformable DETR in `QRDeformableDetrTransformerDecoder` in [/mmdet/models/utils/transformer.py](/mmdet/models/utils/transformer.py). Note Deformable DETR requires 32 as training batchsize and we follow this setting.
+Similarly, We provide two implementation instances of SQR-deformable DETR in `QRDeformableDetrTransformerDecoder` in [/mmdet/models/utils/transformer.py](/mmdet/models/utils/transformer.py). Named as `forward` and `forward_slow`, separately.
 
 __NOTE:__
 Please use `mmcv_full==1.3.3` and `pytorch>=1.5.0` for correct reproduction.
