Hi. Try to use CUDA in Theano.
When I start the script i have an error
"ERROR (theano.gpuarray): pygpu was configured but could not be imported or
is too old (version 0.7 or higher required)"
My theanorc
[cuda]
root=C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0
[blas]
ldflags=-lopenblas
[global]
device = cuda
floatX = float32
Windows 10 x64.
script
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')
Display is "Used the cpu"
How can fix it?
