我在GPU上运行Theano测试代码时遇到问题。我遵循了官方的Theano安装指南，之后我没有按照本指南工作：https://github.com/philferriere/dlwin。但是我仍然无法在GPU上运行代码，并且会出现一些奇怪的行为。
测试示例我想运行：
var AngularModuleComponent = function( container, state ) {
var html = $( '#' + state.templateId ).html(),
element = container.getElement();
element.html(html);
angular
.module( state.module )
angular.bootstrap( element[ 0 ], [ state.module ] );
}
在Pycharm中运行时出现以下错误：
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')
但是当我尝试从控制台导入theano时，我收到以下错误：

我安装了最新的64位版cuda（cuda-8.0.44），我有一个64位python 3.5.2，theano realease 0.8.2，NVIDIA GTX 680，Microsoft visual studio 2015。
我一直困扰着24小时，我的想法已经不多了。 提前感谢您的帮助！
编辑：在PyCharm中导入theano工作正常，我在两种情况下使用相同的python
