Data & Pre-trained Models

• Prepare MSCOCO data follow link.
• Download pretrained Bert and Faster-RCNN from Baidu Cloud Disk [code: 0j9f] or Google Drive.
  • It's an unified checkpoint file, containing a pretrained Bert-base and the fc6 layer of the Faster-RCNN.
• Download our pretrained LaBERT model from Baidu Cloud Disk [code: fpke] or Google Drive.
