PyTorch无法检测到CUDA可能由多种原因引起。以下是一些常见的原因及其解决方案: PyTorch版本不支持CUDA: 确保你安装的PyTorch版本支持CUDA。你可以在PyTorch的官方网站查看支持CUDA的PyTorch版本,并使用适当的安装命令进行安装。例如,如果你需要安装支持CUDA 11.1的PyTorch,可以使用以下命令: bash pip install torch torchvisi...
cu117表示您安装的是NVidia CUDA 11.7版本，而ROCm需要一个build版本
since updating both my gpu driver and cuda to cuda 12.3 pytorch isnt detecting my gpu and is complaing that cuda is not availible and that i dont have supported gpu when it was working just fine my gpu is a rtx 3060 yes with cuda support ...
可以看出先是调用nvcc编译了.cu,生成了add2_kernel.cuda.o;然后调用c++编译add2.cpp,生成了add2.o;最后调用c++生成动态链接库add2.so。 Setuptools 第二种编译的方式是通过Setuptools,也就是编写setup.py,具体代码如下: from setuptools import setup from torch.utils.cpp_extensionimport BuildExtension, CUDAExten...
让我们看看如何编写这样一个 CUDA 核心,并使用这个扩展机制将其集成到 PyTorch 中。 编写CUDA 扩展的一般策略是首先编写一个 C++文件,定义将从 Python 调用的函数,并使用 pybind11 将这些函数绑定到 Python。此外,这个文件还将声明在CUDA(.cu)文件中定义的函数。然后,C++函数将进行一些检查,并最终将其调用转发到 ...

cmake -DCMAKE_PREFIX_PATH<path_to_your_libtorch> -D CUDA_CUDA_LIB=/usr/lib64/libcuda.so ..这将强制链接到libcuda.so的NVidia驱动程序版本。之后，当我在cpp应用程序中打印时：std::cout << torch::cuda::is_available() << std::endl;，则输出1，而不是之前的0。警告也消失了。
OpenMPI found, but it is not built with CUDA support 由于Ubuntu官方提供的MPI版本并没有在编译时支持CUDA,如果想开启这个特性需要自己重新编译OpenMPI,由于该特性只是减少一次内存拷贝操作,对总体性能影响不大,并且操作过程比较繁琐因此这里不开启该特性。
