c++ - tensorflow 错误此文件需要编译器和库支持 ISO C++ 2011 标准

Question

结果如下，我运行项目stylegan2，但是失败了。所以我需要帮助。链接是https://github.com/NVlabs/stylegan2

我需要帮助。

我遇到了同样的错误。一个讨厌的解决方法是添加标志 --std=c++11和 -DNDEBUG到 nvcc调用 dnnlib/tflib/custom_ops.py ln 64 :

cmd = 'nvcc --std=c++11 -DNDEBUG ' + opts.strip()

为什么同时使用--std 和-DNDEBUG？

刚刚 --std=c++11给了我以下错误:

RuntimeError: NVCC returned an error. See below for full command line and output log:

nvcc --std=c++11 "/usr/lib/python3.6/site-packages/tensorflow/python/_pywrap_tensorflow_internal.so" --compiler-options '-fPIC -D_GLIBCXX_USE_CXX11_ABI=0' --gpu-architecture=sm_75 --use_fast_math --disable-warnings --include-path "/usr/lib/python3.6/site-packages/tensorflow/include" --include-path "/usr/lib/python3.6/site-packages/tensorflow/include/external/protobuf_archive/src" --include-path "/usr/lib/python3.6/site-packages/tensorflow/include/external/com_google_absl" --include-path "/usr/lib/python3.6/site-packages/tensorflow/include/external/eigen_archive" 2>&1 "/home/username/stylegan2/dnnlib/tflib/ops/fused_bias_act.cu" --shared -o "/tmp/tmp8nryqyhs/fused_bias_act_tmp.so" --keep --keep-dir "/tmp/tmp8nryqyhs"

/usr/lib/python3.6/site-packages/tensorflow/include/absl/strings/string_view.h(495): error: constexpr function return is non-constant

1 error detected in the compilation of "/tmp/tmp8nryqyhs/fused_bias_act.cpp1.ii".

这是通过使用标志 -DNDEBUG 来阻止的, as explained in this git thread .

解决方案很丑，作者通过提供更多输入选项或其他东西(或解释如何做)来解决这个问题会很酷。但就目前而言，它会做到。
