Error after upgrading to v0.2
RuntimeError: Expected argument self to have 1 dimension(s), but has 4 at /opt/conda/conda-bld/pytorch_1502006348621/work/torch/csrc/generic/TensorMethods.cpp:23086
Line that has issue
torch.dot(tensor_1, tensor_2)

tensor_1 size: (512L, 256L, 3L, 3L)
tensor_2 size: (512L, 256L, 3L, 3L)

Used to work prior to v0.2 (I downgraded to 0.1.12 and it worked) @Soumith_Chintala
