Hi,

Although I set clip_grad as below, but the grad_norm still explodes... Can anyone help me?

optim_wrapper = dict(
    type='OptimWrapper',
    optimizer=dict(
        _delete_=True, type='AdamW', lr=0.0001, weight_decay=0.0001),
    paramwise_cfg=dict(
        custom_keys={'backbone': dict(lr_mult=0.1, decay_mult=1.0)}),
    clip_grad=dict(max_norm=35., norm_type=2))

The text was updated successfully, but these errors were encountered:
