torch:1.8.1
cuda:11.1
cudnn:8.0.5
cpu:RTX3070
gcc:7.5.0(g++ 7.5.0,c++14需要g++5.2以上)
cmake:3.18.3(3.13.2及以上)
在开始安装前,需要确保已经安装cuda和cudnn。
以及cudnn的版本一定要和cuda的版本对应。
需要注意要将cuda/include/cudnn_version.h文件也移动到/usr/local/cuda/include文件中,
且需要加权限
sudo cp cuda/include/cudnn_version.h /usr/local/cuda/include/
chmod 777 /usr/local/cuda/include/cudnn_version.h

我直接下载的zip文件。
安装依赖:
sudo apt-get install libboost-all-dev
执行命令:
python setup.py bdist_wheel
如果cmake不报错,会创建dist目录,生成文件:
subprocess.CalledProcessError: Command '['cmake', '/home/lu/spconv', '-DCMAKE_PREFIX_PATH=/home/lu/anaconda3/envs/futuredet/lib/python3.7/site-packages/torch', '-DPYBIND11_PYTHON_VERSION=3.7', '-DSPCONV_BuildTests=OFF', '-DCMAKE_CUDA_FLAGS="--expt-relaxed-constexpr"', '-DCMAKE_LIBRARY_OUTPUT_DIRECTORY=/home/lu/spconv/build/lib.linux-x86_64-cpython-37/spconv', '-DCMAKE_BUILD_TYPE=Release']' returned non-zero exit status 1.
这个错误在github上的issue中给出的解决方案是将cudnn_version.h移动到cuda文件夹下:
sudo cp cuda/include/cudnn_version.h /usr/local/cuda/include/
chmod 777 /usr/local/cuda/include/cudnn_version.h
这个错误也是cuda环境配置的问题,
ptxas fatal : Value 'sm_30' is not defined for option 'gpu-name' CMakeFiles/cmTC_686d7.dir/build.make:84: recipe for target 'CMakeFiles/cmTC_686d7.dir/main.cu.o' failed
检查一下~/.bashrc文件中是否有:
export PATH=/usr/local/cuda-11.1/bin:$PATH
export CUDA_ROOT=/usr/local/cuda-11.1
export CUDA_HOME=/usr/local/cuda-11.1
export PATH=$PATH:/usr/local/cuda-11.1/bin
export LD_LIBRARY_PATH=/usr/local/cuda-11.1/lib64:$LD_LIBRARY_PATH
以及检查/usr/local文件夹下,cuda和cuda-11.1的软链接是否正确:
还有一个错误找不到torch包:
Could not find a package configuration file provided by "Torch" with any of the following names.
这个错误的解决就是忽视它,再次执行python setup.py bdist_wheel就好了。
The CUDA compiler "/usr/bin/nvcc" is not able to compile a simple test program.
在CMakeLists.txt文件中添加一句:
set(CMAKE_CUDA_COMPILER “/usr/local/cuda-11.1/bin/nvcc”)
最后编译到95%的时候开始报这个错误:
error: ‘cout’ is not a member of ‘std’
解决方法是在报错的文件中添加一句:
sudo gedit /home/lu/Downloads/spconv/include/spconv/nms.h
#include
ImportError: cannot import name 'spconv_utils' from 'spconv' (/home/lu/Downloads/spconv/spconv/__init__.py)
最后pip安装成功后仍会报这个错误,
解决方法是在~/.barhrc文件中添加一句:
这个路径就是你下载的spconv的路径。
export PYTHONPATH=/home/amy/Documents/spconv/:$PYTHONPATH
