Tensorflow en GPU

Question

He podido trabajar con TensorFlow en la CPU, ahora necesito ejecutarlo en un dispositivo GPU con las siguientes especificaciones:

CPU: Intel Xeon (E5-2670) y win7 64bit y NVIDIA GeForce GTX 980 Ti

Instalé python3.5 y Tensorflow para GPU tal como se describe en la página principal de TF. cuando ejecuto un programa de prueba aquí lo que obtengo cuando intento import Tensorflow :

    (C:/Users/Engine>python
Python 3.5.3 (v3.5.3:1880cb95a742, Jan 16 2017, 16:02:32) [MSC v.1900 64 bit (AM
D64)] on win32
Type "help", "copyright", "credits" or "license" for more information.

¿Alguien tiene una pista de cómo se puede resolver esto?

Answer 1

1. CUDNN podría ser una de las razones. cuDNN v6.0 no funciona para muchas personas. Pruebe con cuDNN v5.1.
2. La importación desde dentro de la carpeta GIT también es una de las razones.

Es bueno saber que 1 trabajó para ti.
