Tensorflow not running on GPU
I have aldready spent a considerable of time digging around on stack overflow and else looking for the answer, but couldn't find anything
Hi all,
I am running Tensorflow with Keras on top. I am 90% sure I installed Tensorflow GPU, is there any way to check which install I did?
I was trying to do run some CNN models from Jupyter notebook and I noticed that Keras was running the model on the CPU (checked task manager, CPU was at 100%).
I tried running this code from the tensorflow website:
# Creates a graph.
a = tf.constant([1.0, 2.0, 3.0, 4.0, 5.0, 6.0], shape=[2, 3], name='a')
b = tf.constant([1.0, 2.0, 3.0, 4.0, 5.0, 6.0], shape=[3, 2], name='b')
c = tf.matmul(a, b)
# Creates a session with log_device_placement set to True.
sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))
# Runs the op.
print(sess.run(c))
And this is what I got:
MatMul: (MatMul): /job:localhost/replica:0/task:0/cpu:0
2017-06-29 17:09:38.783183: I c:\tf_jenkins\home\workspace\release-win\m\windows\py\35\tensorflow\core\common_runtime\simple_placer.cc:847] MatMul: (MatMul)/job:localhost/replica:0/task:0/cpu:0

[[ 22. 28.]
[ 49. 64.]]
Which to me shows I am running on my CPU, for some reason.
I have a GTX1050 (driver version 382.53), I installed CUDA, and Cudnn, and tensorflow installed without any problems. I installed Visual Studio 2015 as well since it was listed as a compatible version.
I remember CUDA mentioning something about an incompatible driver being installed, but if I recall correctly CUDA should have installed its own driver.
Edit: I ran theses commands to list the available devices
from tensorflow.python.client import device_lib
print(device_lib.list_local_devices())
and this is what I get
[name: "/cpu:0"
device_type: "CPU"
memory_limit: 268435456
locality {
}
incarnation: 14922788031522107450
]
and a whole lot of warnings like this
2017-06-29 17:32:45.401429: W c:\tf_jenkins\home\workspace\release-win\m\windows\py\35\tensorflow\core\platform\cpu_feature_guard.cc:45] The TensorFlow library wasn't compiled to use SSE instructions, but these are available on your machine and could speed up CPU computations.
Edit 2
Tried running
pip3 install --upgrade tensorflow-gpu
and I get

Solved: Check comments for solution. Thanks to all who helped!
I am new to this, so any help is greatly appreciated! Thank you.
Answer
To check which devices are available to TensorFlow you can use this and see if the GPU cards are available:
from tensorflow.python.client import device_lib
print(device_lib.list_local_devices())
Edit Also, you should see this kind of logs if you use TensorFlow Cuda version :
I tensorflow/stream_executor/dso_loader.cc:128] successfully opened CUDA library libcublas.so.*.* locally
I tensorflow/stream_executor/dso_loader.cc:128] successfully opened CUDA library libcudnn.so.*.* locally
I tensorflow/stream_executor/dso_loader.cc:128] successfully opened CUDA library libcufft.so.*.* locally
