Hi, thanks for the great work!
I am trying to run training for multip-frames code. Could you please tell where to download backbone params?
seem from the code https://github.com/clks-wzz/FAS-SGTD/blob/master/fas_sgtd_multi_frame/generate_network.pyat line 460:
tf.train.init_from_checkpoint(os.path.join(
'model_finetune', 'model.ckpt-9501'),
{v.name.split(':')[0]: v for v in variables_to_restore})
