我正在编译一个CUDA程序，它看起来很混乱（或者，我可能很困惑）关于cmath和math使用的命名空间。当我运行make时，我得到以下输出：
innovationcommons@IC-VR1:~/PackageDownloads/warp-ctc/build$ make VERBOSE=1

CMake Warning at CMakeLists.txt:48 (FIND_PACKAGE):
By not providing "FindTorch.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Torch", but
CMake did not find one.
Could not find a package configuration file provided by "Torch" with any of
the following names:
TorchConfig.cmake
torch-config.cmake
Add the installation prefix of "Torch" to CMAKE_PREFIX_PATH or set
"Torch_DIR" to a directory containing one of the above files. If "Torch"
provides a separate development package or SDK, be sure it has been
installed.

我得到的错误是isinf和isnan不属于std命名空间。我的理解是，如果导入math.h，则情况属实，但如果导入cmath.h则不行。但是，我可以在上一个编译行中看到std=c++11，当我检查test_gpu.cu时，我看到正在导入cmath：
#include <cmath>
#include <random>
#include <tuple>
#include <vector>
#include <iostream>
此时，我真的不知道如何继续。任何想法或建议都会有所帮助......
ADDENDUM：这是值得的，这是我的编译器信息：
