Setup

Environment

First, setup EVA-02 pre-training & image classification environment.

Then, install mmcv==1.7.1 and mmsegmentation==0.29.1.

Data

Please prepare ADE20K datasets according to the guidelines in MMSegmentation.

EVA-02 pre-trained weight

model name	#params	MIM pt dataset	MIM pt epochs	weight
eva02_B_pt_in21k_p14to16	86M	IN-21K	150	🤗 HF link

• eva02_psz14to16 models interpolate the kernel size of patch_embed from 14x14 to 16x16, and interpolate the pos_embed from 16x16 to 14x14. This is useful for object detection, instance segmentation & semantic segmentation tasks.

Evaluation

Evaluate eva02_B_ade_seg_upernet_sz512 on ADE20K using a single node with 4 gpus.
