Tensorflow cannot use GPU

Question

I have installed CUDA because I need to run some Deep Neural Network models, but Tensorflow is still unable to see the gpu

from tensorflow.python.client import device_lib
print(device_lib.list_local_devices())

It shows only the CPU.

How can I get Tensorflow to use my gpu?

error log I get when I import keras with tensorflow-gpu installed ImportError: Traceback (most recent call last): File "C:\\Users\\Monviso\\Anaconda3\\lib\\site-packages\\tensorflow\\python\\pywrap_tensorflow_internal.py", line 18, in swig_import_helper return importlib.import_module(mname) File "C:\\Users\\Monviso\\Anaconda3\\lib\\importlib__init__.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "", line 978, in _gcd_import File "", line 961, in _find_and_load File "", line 950, in _find_and_load_unlocked File "", line 648, in _load_unlocked File "", line 560, in module_from_spec File "", line 922, in create_module File "", line 205, in _call_with_frames_removed ImportError: DLL load failed: The specified module could not be found.

During handling of the above exception, another exception occurred:

Answer 1

Your Cuda version is the problem. Only the tensorflow version 1.5 supports CUDA 9 and cuDNN 7. The previous versions of the Tensorflows support only CUDA 8 and cuDNN 6. If you have installed using anaconda it is very likely that you have not installed version 1.5. Use pip or pip3 to install.

Since you are using a windows machine check this link to install tensorflow with gpu support.

Check this link to see which version require what Cuda and Cudnn

I recommend you to uninstall both the CPU and GPU version of tensorflow and install afresh.

If you wanna keep your cuda version to 9 then install tensorflow version 1.5. If you install using anaconda it is likely you will get version 1.4 which supports only Cuda 8
