It is indeed not exposed.
You can access it via something like this which is an autogenerated binding: https://github.com/pytorch/pytorch/blob/master/torch/nn/functional.py#L473 29
 torch.nn._functions.thnn.auto.TemporalRowConvolution.forward
 torch.nn._functions.thnn.auto.TemporalRowConvolution.backward
 torch.nn._functions.thnn.auto.TemporalRowConvolution.apply

These should be available, but we haven’t exposed them as PyTorch nn modules yet.
