OS:OSX 10.11.4如何在OSX上使用theano與GPU?
GPU:的GeForce GT 750M,CUDA7.5
語言:Python的蟒蛇2.7
我按照我的Mac上theano的設置CUDA指令:
- 設置PATH:出口PATH = /開發/ NVIDIA/CUDA-7.5/bin中:$ PATH
- 集LD_LIBRARY_PATH:出口LD_LIBRARY_PATH = /開發/ NVIDIA/CUDA-7.5/lib目錄:$ LD_LIBRARY_PATH
- 創建.theanorc文件,並添加CUDA_ROOT = /開發商/ NVIDIA/CUDA的7.5 [CUDA]節
我複製從theano網站的代碼並將其粘貼到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')
但是當我運行這條線:
THEANO_FLAGS='floatX=float32,device=gpu0,nvcc.fastmath=True' python test.py
我得到這個錯誤:
nvcc fatal: The version ('70300') of the host compiler ('Apple clang') is not supported
,並警告看起來是這樣的:
WARNING (theano.sandbox.cuda): CUDA is installed, but device gpu0 is not available (error: cuda unavailable)
是因爲我的Xcode的版本,它的東西(這是7.3版)?如何解決這個問題呢?
