Question

我正试图在由anaconda创建的python虚拟环境中的NVIDIA 1060 GPU上使用Cuda 8.0在Ubuntu 16.04上运行theano简单代码。以下是我的theanorc文件：

else if

我试图运行的代码是来自theano网站的简短示例：

[global]
floatX = float32
device = cuda

当我运行代码时，我收到一堆警告并出现以下错误：

from theano import function, config, shared, tensor
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([], tensor.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, tensor.Elemwise) and
              ('Gpu' not in type(x.op).__name__)
              for x in f.maker.fgraph.toposort()]):
    print('Used the cpu')
else:
    print('Used the gpu')

令人惊讶的是，代码RUNS并打印所需的输出如下：

ERROR (theano.sandbox.cuda): Failed to compile cuda_ndarray.cu: ('nvcc return status', 1, 'for cmd', 'nvcc -shared -O3 -m64 -Xcompiler -DCUDA_NDARRAY_CUH=c72d035fdf91890f3b36710688069b2e,-DNPY_NO_DEPRECATED_API=NPY_1_7_API_VERSION,-fPIC,-fvisibility=hidden -Xlinker -rpath,/home/eb/.theano/compiledir_Linux-4.8--generic-x86_64-with-debian-stretch-sid-x86_64-2.7.13-64/cuda_ndarray -I/home/eb/anaconda2/envs/deep/lib/python2.7/site-packages/theano/sandbox/cuda -I/home/eb/anaconda2/envs/deep/lib/python2.7/site-packages/numpy/core/include -I/home/eb/anaconda2/envs/deep/include/python2.7 -I/home/eb/anaconda2/envs/deep/lib/python2.7/site-packages/theano/gof -L/home/eb/anaconda2/envs/deep/lib -o /home/eb/.theano/compiledir_Linux-4.8--generic-x86_64-with-debian-stretch-sid-x86_64-2.7.13-64/cuda_ndarray/cuda_ndarray.so mod.cu -lcublas -lpython2.7 -lcudart')

Mapped name None to device cuda: GeForce GTX 1060 6GB (0000:01:00.0)

我想知道我是否错过了Theano配置或什么？对于出了什么问题的任何想法？

P.S。除了安装在系统级别的Cuda库之外，所有库都已安装在我的python虚拟环境中。 --Thanks

theano无法编译cuda，但python代码使用GPU运行
