经过一场大战，我终于能够让Theano在OSX中使用GPU。 但是现在，我已经尝试了我能记住的一切，而Theano仍然无法使用CuDNN。
我安装了CUDA版本7和CUDNN版本3.
我尝试将库复制到/usr/local/cuda/lib以及/usr/local/cuda/lib64，将包含文件复制到/usr/local/cuda/include
我的.theanorc是
[global]
floatX = float32
device = gpu
force_device = True
allow_gc = False
optimizer_including=cudnn
# warn_float64 = warn
# openmp = True
[nvcc]
fastmath = True
flags = -L/Users/morgado/anaconda/lib/
[cuda]
root = /usr/local/cuda
[gcc]
cxxflags = -L/usr/local/cuda/lib64
我的.profile有相关部分：
# CUDA
CUDA_ROOT=/usr/local/cuda
export PATH=$CUDA_ROOT/bin:$PATH
export DYLD_LIBRARY_PATH=$CUDA_ROOT/lib:$DYLD_LIBRARY_PATH
export LD_LIBRARY_PATH=$CUDA_ROOT/lib:$CUDA_ROOT/lib64:$LD_LIBRARY_PATH
但是当我试图让Theano使用CUDNN时，我得到的更多（使用lib64中的文件）给了我错误：

似乎clang没有得到cudnn库，即使我特意告诉它检查那条路。
答案 0 :(得分：3)
在您的个人资料中添加：
export LIBRARY_PATH=$CUDA_ROOT/lib:$CUDA_ROOT/lib64:$LIBRARY_PATH
在LIBRARY_PATH上包含lib对我有用。
答案 1 :(得分：0)
我遇到了同样的问题，可以通过设置
来修复它export DYLD_LIBRARY_PATH=/Developer/NVIDIA/CUDA-7.5/lib:$DYLD_LIBRARY_PATH
在我的.bashrc并正在运行
sudo update_dyld_shared_cache
之后。
