nvcc致命:虽然Visual Studio 12.0已添加到PATH,但在PATH中找不到编译器'cl.exe'

Question

我已按照https://datanoord.com/2016/02/01/setup-a-deep-learning-environment-on-windows-theano-keras-with-gpu-enabled/的所有说明进行操作, 但似乎无法让它工作.

我已将C:\ Program Files(x86)\ Microsoft Visual Studio 12.0\VC\bin添加到我的PATH变量中

每次我从Theano网站运行代码来测试是否使用了CPU或GPU时,它会给我一个致命的错误:"nvcc致命:在PATH中找不到编译器'cl.exe'"

这是我用来测试的代码:

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')

我怎么解决这个问题？

Answer 1

我有同样的问题。我使用的是 64 位 Windows 8.1，我必须将以下内容添加到我的路径中，现在它工作正常：

C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\amd64

C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\amd64\cl.exe

希望这可以帮助
