3080卡 cuda11.3 編譯caffe報錯與解決
首先需要把cudnn關閉. cuda11只支持cudnn8,caffe支持7.X. 這個暫時解決不了,所以先關閉,不用cudnn加速.
另外補充一下,一開始還不知道我機器是3080卡,用nvidia-smi命令看不到顯卡型號,用lspci |grep -i vga顯示如下
01:00.0 VGA compatible controller: NVIDIA Corporation Device 2208 (rev a1)
我一看就認為是20卡了,然后電腦就裝cuda10.0,cudnn7.5. 然后編譯caffe,解決若干問題確實能夠編譯成功,但是運行的時候加載caffe模型的時候卡住:
net = caffe.Net(path_deploy, path_caffe_model, caffe.TEST)
運行這句話加載模型權重,加載第一層卷積層的時候就卡住,卡很久,能卡15min左右才能出來.
然后找問題無解,然后看機箱里面卡是3080的,大坑啊!

解決方案1:這個是用make編譯的,換cmake編譯就不會報這個錯誤
解決方案2: make這個錯誤解決,按照提示Define THRUST_IGNORE_CUB_VERSION_CHECK to ignore this.
在Makefile文件中添加 -DTHRUST_IGNORE_CUB_VERSION_CHECK,如下:
NVCCFLAGS += -ccbin=$(CXX) -Xcompiler -fPIC -DTHRUST_IGNORE_CUB_VERSION_CHECK $(COMMON_FLAGS)
