torch.utils.serialization.read_lua_file.T7ReaderException: unknown type id 7565827. The file may be corrupted.

I am trying to convert a couple of pre-trained VQA models from another repository and i am getting this error `torch.utils.serialization.read_lua_file.T7ReaderException: unknown type id 7565827. The file may be corrupted.` I am not sure what the issue is. I also added `long_size=8 ` as suggested in another issue. Could someone help me out?
