caffe编译报错“nvcc fatal : Unsupported gpu architecture ‘compute_86‘”
显卡3050Ti(算力可以达到8.6 可查询)
cuda:11.0
由于cuda11.0不支持算力8.6的GPU 因此修改 ~/.bashrc中的信息
sudo ge
在cuda配置文件下面增加：
export TORCH_CUDA_ARCH_LIST="8.0"
然后：
source ~/.bashrc
发现还是caffe调用的是8.6的算力，
参考
另一个办法，直接修改caffe中的cmake文件夹下面的cuda.cmake
修改cuda.cmake 文件内容
参考
# Function for selecting GPU arch flags for nvcc based on CUDA_ARCH_NAME
# Usage:
# caffe_select_nvcc_arch_flags(out_variable)
function(caffe_select_nvcc_arch_flags out_variable)
# List of arch names
set(__archs_names "Fermi" "Kepler" "Maxwell" "Pascal" "All" "Manual")
set(__archs_name_default "All")
if(NOT CMAKE_CROSSCOMPILING)
list(APPEND __archs_names "Auto")
set(__archs_name_default "Auto")
endif()
改为：
# Function for selecting GPU arch flags for nvcc based on CUDA_ARCH_NAME
# Usage:
# caffe_select_nvcc_arch_flags(out_variable)
function(caffe_select_nvcc_arch_flags out_variable)
# List of arch names
set(__archs_names "Ampere" "Kepler" "Maxwell" "Pascal" "All" "Manual")
set(__archs_name_default "All")
if(NOT CMAKE_CROSSCOMPILING)
list(APPEND __archs_names "Auto")
set(__archs_name_default "Auto")
endif()
# verify CUDA_ARCH_NAME value
if(NOT ";${__archs_names};" MATCHES ";${CUDA_ARCH_NAME};")
string(REPLACE ";" ", " __archs_names "${__archs_names}")
message(FATAL_ERROR "Only ${__archs_names} architeture names are supported.")
endif()
改为
# verify CUDA_ARCH_NAME value
if(NOT ";${__archs_names};" MATCHES ";${CUDA_ARCH_NAME};")
string(REPLACE ";" ", " __archs_names "${__archs_names}")
message(FATAL_ERROR "Only ${__archs_names} architeture names are supported.")
elseif(${CUDA_ARCH_NAME} STREQUAL "Ampere")
set(__cuda_arch_bin "86")
endif()
if(${CUDA_ARCH_NAME} STREQUAL "Fermi")
set(__cuda_arch_bin "20 21(20)")
elseif(${CUDA_ARCH_NAME} STREQUAL "Kepler")
set(__cuda_arch_bin "30 35")
elseif(${CUDA_ARCH_NAME} STREQUAL "Maxwell")
set(__cuda_arch_bin "50")
elseif(${CUDA_ARCH_NAME} STREQUAL "Pascal")
set(__cuda_arch_bin "60 61")
elseif(${CUDA_ARCH_NAME} STREQUAL "All")
set(__cuda_arch_bin ${Caffe_known_gpu_archs})
elseif(${CUDA_ARCH_NAME} STREQUAL "Auto")
caffe_detect_installed_gpus(__cuda_arch_bin)
else() # (${CUDA_ARCH_NAME} STREQUAL "Manual")
set(__cuda_arch_bin ${CUDA_ARCH_BIN})
endif()
改为
if(${CUDA_ARCH_NAME} STREQUAL "Fermi")
set(__cuda_arch_bin "20 21(20)")
elseif(${CUDA_ARCH_NAME} STREQUAL "Kepler")
set(__cuda_arch_bin "30 35")
elseif(${CUDA_ARCH_NAME} STREQUAL "Maxwell")
set(__cuda_arch_bin "50")
elseif(${CUDA_ARCH_NAME} STREQUAL "Pascal")
set(__cuda_arch_bin "60 61")
elseif(${CUDA_ARCH_NAME} STREQUAL "All")
set(__cuda_arch_bin ${Caffe_known_gpu_archs})
elseif(${CUDA_ARCH_NAME} STREQUAL "Auto")
#caffe_detect_installed_gpus(__cuda_arch_bin)
set(__cuda_arch_bin "60 61")
else() # (${CUDA_ARCH_NAME} STREQUAL "Manual")
set(__cuda_arch_bin ${CUDA_ARCH_BIN})
endif()
结果：
最后发现caffe使用的算力6.0的 之前的保存问题解决。
其实这样存在一个问题，最好是caffe的cuda.cmake 的算力与~/.bashrc中的设置算力保持一直，否则可能出现在抵用caffe框架时候 出现算力不匹配问题，例如：
Check failed: error == cudaSuccess (209 vs. 0) no kernel image is available
所以需要把：
if(${CUDA_ARCH_NAME} STREQUAL "Fermi")
set(__cuda_arch_bin "20 21(20)")
elseif(${CUDA_ARCH_NAME} STREQUAL "Kepler")
set(__cuda_arch_bin "30 35")
elseif(${CUDA_ARCH_NAME} STREQUAL "Maxwell")
set(__cuda_arch_bin "50")
elseif(${CUDA_ARCH_NAME} STREQUAL "Pascal")
set(__cuda_arch_bin "60 61")
elseif(${CUDA_ARCH_NAME} STREQUAL "All")
set(__cuda_arch_bin ${Caffe_known_gpu_archs})
elseif(${CUDA_ARCH_NAME} STREQUAL "Auto")
#caffe_detect_installed_gpus(__cuda_arch_bin)
set(__cuda_arch_bin "80")
else() # (${CUDA_ARCH_NAME} STREQUAL "Manual")
set(__cuda_arch_bin ${CUDA_ARCH_BIN})
endif()
/.bashrc中需要添加为：
export TORCH_CUDA_ARCH_LIST=“8.0”
这样编译，之后 GPU算力是一致的。
又出现新问题：

（针对ubuntu）
打开caffe文件下的makefile
扎到ifeq ($(OSX), 1)
将
ifeq ($(OSX), 1)
CXX := /usr/bin/clang++
改为
ifeq ($(LINUX), 1)
CXX ?= /usr/bin/g++ -std=c++11
如果是mac则改为：
ifeq ($(OSX), 1)
CXX := /usr/bin/clang++ -std=c++11
参考
参考
如果是cmake编译 则修改 caffe中的cmakelist.txt中的
if(UNIX OR APPLE)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fPIC -Wall")
endif()
改为：
if(UNIX OR APPLE)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fPIC -Wall -std=c++11")
endif()
参考
如果还报错
问题出在gcc和g++版本问题上，说是 caffe是在gcc4.9版本上编译，大于4.9的版本会出现问题，因此要安装gcc 4.9 g++4.9版本
由于系统是ubuntu20.04 已经没有这个软件包，因此
需要修改源：
sudo gedit /etc/apt/sources.list
末尾添加：
deb http://dk.archive.ubuntu.com/ubuntu/ xenial main
deb http://dk.archive.ubuntu.com/ubuntu/ xenial universe
sudo apt update
安装gcc 和g++
sudo apt install g++-4.9
sudo apt install gcc-4.9
最后涉及到多gcc g++版本的切换 ：
设置gcc4.9 和g++的权重：
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 25
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.9 25
切换：
sudo update-alternatives --config gcc
sudo update-alternatives --config g++

下载protoc2.6.1版本
https://github.com/protocolbuffers/protobuf/releases/tag/v2.6.1
ubuntu安装caffe中涉及到protobuf
安装教程：
安装
安装完记得刷新
sudo ldconfig
报错：
fatal error: google/protobuf/arena.h: No such file or directory
说是3.3.0解决了该问题,卸载2.6.1
参考：https://blog.csdn.net/h799710/article/details/126762153
还是存在问题 貌似是 conda中的protobuf影响
在Gen6D中安装了 protobuf 3.20.3
卸载 pip uninstall protobuf
在dsp-slam中安装了protobuf 3.19.1
卸载 pip uninstall protobuf
