nvcc fatal : Cannot find compiler 'cl.exe' in PATH although Visual Studio 12.0 is added to PATH
<p>I have followed all the instructions from <a href="https://datanoord.com/2016/02/01/setup-a-deep-learning-environment-on-windows-theano-keras-with-gpu-enabled/" rel="noreferrer">https://datanoord.com/2016/02/01/setup-a-deep-learning-environment-on-windows-theano-keras-with-gpu-enabled/</a>
but can't seem to get it work.</p>

<p>I have added 
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin
to my PATH variable</p>

<p>Every time I run the code from the Theano website to test whether a CPU or GPU is used, it gives me a fatal error of 
"nvcc fatal   : Cannot find compiler 'cl.exe' in PATH"</p>

<p>Here is the code I use to test:</p>

<pre><code>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')
</code></pre>

<p>How can I solve this? </p>
