Did you install Cuda and cudnn?

https://developer.nvidia.com/accelerated-computing-toolkit

from leaf.

yep, i am sure i've installed them since I can compile and run other applications.

they are located at

/usr/lib/x86_64-linux-gnu/libcudnn.so
/usr/lib/x86_64-linux-gnu/libcuda.so

from leaf.

may be the cudnn version not match, try cudnn v3

from leaf.

jakelee8 commented on August 16, 2024

This Stack Overflow answer fix that problem for me.

export LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/

from leaf.

Though now, I'm running into undefined symbol errors.

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

OS: Mac OS X 10.11.5

Cargo configuration: native + cuda

[features]
default = ["native", "cuda"]
native = ["leaf/native", "collenchyma/native"]
opencl = ["leaf/opencl", "collenchyma/opencl"]
cuda = ["leaf/cuda", "collenchyma/cuda"]

btw, I had to disable opencl support because the crate uses the -lOpenCL instead of '-framework OpenCL` flag needed on Mac OS.

Edit: there's an issue for this in the examples directory: autumnai/leaf-examples#9

from leaf.
