Hi
I’m trying to build PyTorch 1.7.1 from source using CUDA 11.1 on Windows (build worked fine on Ubuntu 18.04, now needs the Windows version)
I’m following this thread: PyTorch build from source on Windows - #17 by mmisiur 4 and I keep getting these errors:
..\aten\src\ATen/core/dispatch/Dispatcher.h(368): error C2039: 'boxArgs': is not a member of 'c10::impl::BoxedKernelWrapper<Return (at::Tensor &,const at::Tensor &,c10::optional<c10::MemoryFormat>),void>'
        with
        [
            Return=at::Tensor &
        ]
..\aten\src\ATen/core/dispatch/Dispatcher.h(368): note: see declaration of 'c10::impl::BoxedKernelWrapper<Return (at::Tensor &,const at::Tensor &,c10::optional<c10::MemoryFormat>),void>'
        with
        [
            Return=at::Tensor &
        ]
..\aten\src\ATen/core/boxing/impl/boxing.h(100): error C2070: 'FuncType': illegal sizeof operand
        with
        [
            FuncType=at::Tensor (const at::Tensor &,c10::optional<c10::MemoryFormat>)
        ]

CMake summary output (not enough room to post entire output, will post later if needed):
