torch does not do DNNL

[undertherain]

unite do_torch and do_pytorch or make do_torch support DNNL backend

[undertherain]

For time being is seems I've hardcoded DNNL support by some redunant code but it fails with the following error

Need to look at do_torch.py and do_pytorch.py and find the redundant DNNL code and make it nice OOPish-thingy!
