Issue installing Tensorflow -- not a CUDA/CuDNN issue

I recently started getting into Tensorflow, but i'm having issues with the install. Everytime I try to import it I get the following error

>>> import tensorflow as tf

Failed to load the native TensorFlow runtime.

I looked at other stack overflow posts that were having the same problem as me, and they suggested getting the CUDA libraries from NVIDIA. The problem is, I have neither a NVIDIA graphics card nor the GPU version of tensorflow, so I don't think that's the issue. There were also suggestions to make sure the Microsoft redistributables for visual studio are installed, which they are.

If this is a system variable based problem, I'd appreciate help with changing system variables as I'm new to doing that. Thank you!

Some System Info:

• OS: Microsoft Windows 10 Pro Version 10.0.17134
• CPU: Intel Xeon E5620
• Graphics Card: Radeon RX 480
• Python Version: 3.6.5 amd64 Tensorflow
• Install method: pip install tensorflow

@user1735003 figured it out. I unistalled the latest version of tensorflow

pip uninstall tensorflow

and then installed tensorflow 1.5

pip install tensorflow==1.5

then I verified the installation worked with the script

import tensorflow as tf
hello = tf.constant('Hello, TensorFlow!')
sess = tf.Session()
print(sess.run(hello))

I got the correct output

Hello, TensorFlow!

My guess is that you are trying to use TF >= 1.6, because your CPU is rather old and does not support AVX instructions. Indeed from 1.6 on, tensorflow pre-built binaries use AVX instructions.

Currently your options are either to:

1. Use an official pre-built binary of TF 1.5 or earlier. (You will miss a few things but it's still OK I would say).
2. Search for an unofficial pre-built binary of TF >= 1.6 that does not support AVX.
   • Currently, pre-built binaries until TF 1.10 from conda install on Windows seem not to be built with AVX support, although I could not find this information anywhere and therefore cannot tell if this is intentional and how long that will be the case.
   • Beware that binaries from conda-forge (which used to be the main conda tensorflow provider before it has been available on the main channel) on the other hand are built with AVX support.
3. Change your hardware to support AVX (obviously).
4. Compile your own binary of tensorflow without AVX instructions. A reasonable option if none of the others were possible.
