Tensorflow not detecting GPU

Open riturajsoni opened this issue 7 years ago • 0 comments

I have installed Anaconda + tensor flow + CUDA on my system

  1. Anaconda version installed : Anaconda3-4.2.0-Windows-x86_64
  2. tensorflow for gpu is installed using pip install command.
  3. Cuda version installed as: cuda_9.0.176_win10 and its patch is also installed
  4. Then files from cudnn like bin, include, lib copied to installation path
  5. The graphics card is NVIDIA GeForce 820M
  6. but when I run simple python scsript

import tensorflow as tf with tf.device('/gpu:0'): 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)

with tf.Session() as sess: print (sess.run(c))

This error appears:

It is not detecting the gpu. Please suggest solution for it.
