2f1932fc - Fix issues in torch::tensor constructor (#26890)

Fix issues in torch::tensor constructor (#26890) Summary: This PR contains the following: 1. Fix ambiguous overload problem when `torch::tensor({{1, 2}})` is used: ``` ../test/cpp/api/tensor.cpp: In member function ‘virtual void TensorTest_MultidimTensorCtor_Test::TestBody()’: ../test/cpp/api/tensor.cpp:202:41: error: call of overloaded ‘tensor(<brace-enclosed initializer list>)’ is ambiguous auto tensor = torch::tensor({{1, 2}}); ^ In file included from ../caffe2/../torch/csrc/api/include/torch/types.h:7:0, from ../caffe2/../torch/csrc/api/include/torch/detail/static.h:4, from ../caffe2/../torch/csrc/api/include/torch/nn/pimpl.h:4, from ../caffe2/../torch/csrc/api/include/torch/nn/module.h:3, from ../caffe2/../torch/csrc/api/include/torch/nn/cloneable.h:3, from ../test/cpp/api/support.h:7, from ../test/cpp/api/tensor.cpp:2: ../torch/csrc/autograd/generated/variable_factories.h:177:644: note: candidate: at::Tensor torch::tensor(c10::ArrayRef<unsigned char>) ../torch/csrc/autograd/generated/variable_factories.h:177:1603: note: candidate: at::Tensor torch::tensor(c10::ArrayRef<signed char>) ../torch/csrc/autograd/generated/variable_factories.h:177:2562: note: candidate: at::Tensor torch::tensor(c10::ArrayRef<short int>) ../torch/csrc/autograd/generated/variable_factories.h:177:3507: note: candidate: at::Tensor torch::tensor(c10::ArrayRef<int>) ../torch/csrc/autograd/generated/variable_factories.h:177:4450: note: candidate: at::Tensor torch::tensor(c10::ArrayRef<long int>) ../torch/csrc/autograd/generated/variable_factories.h:177:5404: note: candidate: at::Tensor torch::tensor(c10::ArrayRef<float>) ../torch/csrc/autograd/generated/variable_factories.h:177:6354: note: candidate: at::Tensor torch::tensor(c10::ArrayRef<double>) ../torch/csrc/autograd/generated/variable_factories.h:177:7630: note: candidate: at::Tensor torch::tensor(c10::ArrayRef<bool>) ../torch/csrc/autograd/generated/variable_factories.h:177:9224: note: candidate: at::Tensor torch::tensor(c10::ArrayRef<c10::Half>) ../torch/csrc/autograd/generated/variable_factories.h:177:10838: note: candidate: at::Tensor torch::tensor(c10::ArrayRef<c10::BFloat16>) In file included from ../caffe2/../torch/csrc/api/include/torch/types.h:7:0, from ../caffe2/../torch/csrc/api/include/torch/detail/static.h:4, from ../caffe2/../torch/csrc/api/include/torch/nn/pimpl.h:4, from ../caffe2/../torch/csrc/api/include/torch/nn/module.h:3, from ../caffe2/../torch/csrc/api/include/torch/nn/cloneable.h:3, from ../test/cpp/api/support.h:7, from ../test/cpp/api/tensor.cpp:2: ../torch/csrc/autograd/generated/variable_factories.h:193:19: note: candidate: at::Tensor torch::tensor(torch::detail::InitListTensor) inline at::Tensor tensor(detail::InitListTensor list_init_tensor) { ^ ``` After this PR, the multidim tensor constructor `torch::tensor(...)` should be ready for general use.
