xavier和xavierNX的cuda版本问题

在xavier和xavier NX上面的cuda版本不一致,花点时间看些有哪些东西不一样,在xavier上面是cuda10.0和cudnn7.在xavier NX上面是cuda10.2和cudnn8.

以编译darknet为例.darknet的makefile有关cuda的东西如下:


ifeq ($(GPU), 1)
COMMON&＃43;&＃61; -DGPU -I/usr/local/cuda/include/
CFLAGS&＃43;&＃61; -DGPU
ifeq ($(OS),Darwin) #MAC
LDFLAGS&＃43;&＃61; -L/usr/local/cuda/lib -lcuda -lcudart -lcublas -lcurand
else
LDFLAGS&＃43;&＃61; -L/usr/local/cuda/lib64 -lcuda -lcudart -lcublas -lcurand
endif
endififeq ($(CUDNN), 1)
COMMON&＃43;&＃61; -DCUDNN
ifeq ($(OS),Darwin) #MAC
CFLAGS&＃43;&＃61; -DCUDNN -I/usr/local/cuda/include
LDFLAGS&＃43;&＃61; -L/usr/local/cuda/lib -lcudnn
else
CFLAGS&＃43;&＃61; -DCUDNN -I/usr/local/cudnn/include
LDFLAGS&＃43;&＃61; -L/usr/local/cudnn/lib64 -lcudnn
endif
endif

首先看-lcuda -lcudart -lcublas -lcurand这四个库,

find / -iname "libcuda*"得到/usr/lib/aarch64-linux-gnu/libcuda.soll /usr/lib/aarch64-linux-gnu/libcuda.so得到/usr/lib/aarch64-linux-gnu/libcuda.so -> tegra/libcuda.so*ll /usr/lib/aarch64-linux-gnu/tegra/libcuda.so得到/usr/lib/aarch64-linux-gnu/tegra/libcuda.so -> libcuda.so.1.1*

然后

所以最终是用的libcuda.so.1.1

find / -iname "libcudart.so"得到 /usr/local/cuda-10.0/targets/aarch64-linux/lib/libcudart.soll /usr/local/cuda-10.0/targets/aarch64-linux/lib/libcudart.so得到 /usr/local/cuda-10.0/targets/aarch64-linux/lib/libcudart.so -> libcudart.so.10.0

find / -iname "libcublas.so"得到 /usr/local/cuda-10.0/targets/aarch64-linux/lib/libcublas.soll /usr/local/cuda-10.0/targets/aarch64-linux/lib/libcublas.so
得到 /usr/local/cuda-10.0/targets/aarch64-linux/lib/libcublas.so -> libcublas.so.10.0

find / -iname "libcurand.so"得到 /usr/local/cuda-10.0/targets/aarch64-linux/lib/libcurand.soll /usr/local/cuda-10.0/targets/aarch64-linux/lib/libcurand.so得到 /usr/local/cuda-10.0/targets/aarch64-linux/lib/libcurand.so -> libcurand.so.10.0


find / -iname "libcudnn.so"得到 /usr/lib/aarch64-linux-gnu/libcudnn.soll /usr/lib/aarch64-linux-gnu/libcudnn.so得到 /usr/lib/aarch64-linux-gnu/libcudnn.so -> /etc/alternatives/libcudnn_so*ll /etc/alternatives/libcudnn_so得到 /etc/alternatives/libcudnn_so -> /usr/lib/aarch64-linux-gnu/libcudnn.so.7*ll /usr/lib/aarch64-linux-gnu/libcudnn.so.7/usr/lib/aarch64-linux-gnu/libcudnn.so.7 -> libcudnn.so.7.5.0*
