OS:OSX 10.11.4如何在OSX上使用theano与GPU?
GPU:的GeForce GT 750M,CUDA7.5
语言:Python的蟒蛇2.7
我按照我的Mac上theano的设置CUDA指令:
- 设置PATH:出口PATH = /开发/ NVIDIA/CUDA-7.5/bin中:$ PATH
- 集LD_LIBRARY_PATH:出口LD_LIBRARY_PATH = /开发/ NVIDIA/CUDA-7.5/lib目录:$ LD_LIBRARY_PATH
- 创建.theanorc文件,并添加CUDA_ROOT = /开发商/ NVIDIA/CUDA的7.5 [CUDA]节
我复制从theano网站的代码并将其粘贴到test.py文件:
from theano import function, config, shared, sandbox
import theano.tensor as T
import numpy
import time
vlen = 10 * 30 * 768 # 10 x #cores x # threads per core
iters = 1000
rng = numpy.random.RandomState(22)
x = shared(numpy.asarray(rng.rand(vlen), config.floatX))
f = function([], T.exp(x))
print(f.maker.fgraph.toposort())
t0 = time.time()
for i in range(iters):
r = f()
t1 = time.time()
print("Looping %d times took %f seconds" % (iters, t1 - t0))
print("Result is %s" % (r,))
if numpy.any([isinstance(x.op, T.Elemwise) for x in f.maker.fgraph.toposort()]):
print('Used the cpu')
else:
print('Used the gpu')
但是当我运行这条线:
THEANO_FLAGS='floatX=float32,device=gpu0,nvcc.fastmath=True' python test.py
我得到这个错误:
nvcc fatal: The version ('70300') of the host compiler ('Apple clang') is not supported
,并警告看起来是这样的:
WARNING (theano.sandbox.cuda): CUDA is installed, but device gpu0 is not available (error: cuda unavailable)
是因为我的Xcode的版本,它的东西(这是7.3版)?如何解决这个问题呢?
