Links cannot be deepcopied after to_device('native'). We need to find a workaround or wait until it's fixed. chainer/chainer#5916 solved

Async training requires chainer/chainer#5931 to be fixed.

def deepcopy_link(link):
    device = link.device
    link.to_device(np)
    new_link = copy.deepcopy(link)
    link.to_device(device)
    new_link.to_device(device)
    return new_link

This can be a workaround to deepcopy.

Current ChainerX does not support advanced indexing, which prevents from applying it to CategoricalDQN and IQN. chainer/chainer#5944
