Command to run Theano on GPU (windows)

I talk about the tutorial here http://deeplearning.net/software/theano/tutorial/using_gpu.html The code I use ``` 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') ``` At section Testing Theano with GPU: There are some command line which set Theano flag to run on cpu or gpu. The problem is I have no idea to put these command in. I have try on windows cmd ``` THEANO_FLAGS=mode=FAST_RUN,device=gpu,floatX=float32 python theanogpu_example.py ``` then I get ``` 'THEANO_FLAGS' is not recognized as an internal or external command, operable program or batch file. ``` However, I am able to run the code, on cpu using the command ``` python theanogpu_example.py ``` I want to run the code on GPU, what should I do (with these command in the tutorial)? SOLUTION Thanks to @Blauelf about the idea of windows environment variable. However, the param has to be separated ``` set THEANO_FLAGS="mode=FAST_RUN" & set THEANO_FLAGS="device=gpu" & set THEANO_FLAGS="floatX=float32" & python theanogpu_example.py ```
