Description

🐛 Bug

I have installed PyTorch version 1.8.0 from source and am now attempting to install the C++ API to torchvision 0.9.0 from source.

When making torchvision's C++ API I am getting an error that I need to use a C++14 or later compatible compiler (I am using gcc 9.3.0 which supports C++14):

I think the places of interest are the following:

  • [ 71%] Building CXX object CMakeFiles/torchvision.dir/torchvision/csrc/ops/cpu/roi_pool_kernel.cpp.o
    • Uses the flag -std=gnu++14
  • [ 75%] Building CUDA object CMakeFiles/torchvision.dir/torchvision/csrc/ops/cuda/nms_kernel.cu.o
    • Uses the flag -std=c++11

It seems like all of the CPU builds use the C++14 flag and the CUDA builds (incorrectly) use the C++11 flag.
Can I point this to CMAKE_CUDA_FLAGS being set in vision/CMakeLists.txt? It looks like CUDA_FLAGS contains the flag -std=c++11 as shown in vision/build/CMakeFiles/torchvision.dir/flags.make:

# CMAKE generated file: DO NOT EDIT!
# Generated by "Unix Makefiles" Generator, CMake Version 3.16

# compile CUDA with /usr/local/cuda/bin/nvcc
# compile CXX with /usr/bin/c++
CUDA_FLAGS =  --expt-relaxed-constexpr -Xcompiler=-fPIC   -D_GLIBCXX_USE_CXX11_ABI=1 -std=c++11

Any idea where this is coming from? How it's getting set? And how to change it so that it is set to -std=gnu++14 or similar? Is it coming from my PyTorch install?

  • PyTorch / torchvision Version (e.g., 1.0 / 0.4.0): 1.8.0 / 0.9.0
  • OS (e.g., Linux): Ubuntu 20.04
  • How you installed PyTorch / torchvision (conda, pip, source): source / source
  • Build command you used (if compiling from source): Listed above
  • Python version: 3.8
  • CUDA/cuDNN version: 11.2
  • GPU models and configuration: 3x GeForce GTX 1080

Additional context

The commands I used to build PyTorch:
git clone https://github.com/pytorch/pytorch.git
cd pytorch
git checkout v1.8.0
git submodule sync
git submodule update --init --recursive
python3 setup.py build -j4 --cmake-only
cd build
cmake -DBUILD_CUSTOM_PROTOBUF=0 ..
cmake --build . -j4 --target install
cd ..
python3 setup.py install

Additionally,
python maps to Python 2.7.18
python3 maps to Python 3.8.10

Lastly, I do have a Dockerfile that I am using... but it builds cuDNN, PyTorch, openCV, and torchvision from source... it's about 20GB and takes a few hours to build.

Research direction

Start with vision/CMakeLists.txt and the generated build/CMakeFiles/torchvision.dir/flags.make, then compare the CXX and CUDA compile flags shown in the reproduction. Trace where the CUDA standard flag is set and verify the reproduced torchvision v0.9.0 CUDA build completes with the required C++ standard.
