Issue 1:
It must be a bug, a feature request, or a significant problem with documentation (for small docs fixes please send a PR instead).

BUG

OS Platform and Distribution (e.g., Linux Ubuntu 16.04):

WINDOWS 10.0

TensorFlow installed from (source or binary):

pip (binary)

TensorFlow version (use command below):

1.6

Python version:

tried both python 3.5.2 & 3.6.4

CUDA/cuDNN version:

NO CUDA

GPU model and memory:

NO GPU

Exact command to reproduce:

pip install --upgrade tensorflow

Describe the problem

import tensorflow as tf

give the error (No module named "pywrap_tensorflow")

Issue 42011070 on stack

There : it became clear that it is a cudannxx_x.dll , i.e. CUDA error.

I have tensorflow-gpu running flawlesly on NVIDIA GPU

Source code / logs

No module named _pywrap_tensorflow

Issue 2:
System information

Have I written custom code (as opposed to using a stock example script provided in TensorFlow): No, problem appears on import (import tensorflow as tf).

OS Platform and Distribution (e.g., Linux Ubuntu 16.04): Windows 10 x64

TensorFlow installed from (source or binary): binary (pip --no-cache-dir) install --upgrade tensorflow

TensorFlow version (use command below): 1.6.0 (install says tensorflow-1.6.0-cp36-cp36m-win_amd64.whl)

Python version: 3.6.4 x64

Bazel version (if compiling from source): n/a

GCC/Compiler version (if compiling from source): n/a

CUDA/cuDNN version: n/a

GPU model and memory: n/a

Exact command to reproduce: import tensorflow as tf

You can collect some of this information using our environment capture script:

https://github.com/tensorflow/tensorflow/tree/master/tools/tf_env_collect.sh

You can obtain the TensorFlow version with

python -c "import tensorflow as tf; print(tf.GIT_VERSION, tf.VERSION)"

Describe the problem

When installing tensorflow 1.6.0 the import reports problems. See log below. Tried uninstalled r1.6 and reinstalled 1.5.0 to see if something else might be the problem. 1.5.0 works like a charm. Tried a clean install of 1.6.0 without any luck.

Ran the 'tensorflow_self_check.py' script. See log below.

Failed to load the native TensorFlow runtime.

See https://www.tensorflow.org/install/install_sources#common_installation_problems

for some common reasons and solutions. Include the entire stack trace
above this error message when asking for help.

------------------------

When running 'tensorflow_self_check.py' this is what is reported. Supposed to have installed the CPU version so cuda is not installed.

ERROR: Failed to import the TensorFlow module.

- Python version is 3.6.

- TensorFlow is installed at: C:\Users\Jonas\AppData\Local\Programs\Python\Python36\lib\site-packages\tensorflow

- Could not load 'cudart64_80.dll'. The GPU version of TensorFlow
requires that this DLL be installed in a directory that is named in
your %PATH% environment variable. Download and install CUDA 8.0 from
this URL: https://developer.nvidia.com/cuda-toolkit

- Could not load 'cudnn64_5.dll'. The GPU version of TensorFlow
requires that this DLL be installed in a directory that is named in
your %PATH% environment variable. Note that installing cuDNN is a
separate step from installing CUDA, and it is often found in a
different directory from the CUDA DLLs. You may install the
necessary DLL by downloading cuDNN 5.1 from this URL:
https://developer.nvidia.com/cudnn

- Could not find cuDNN.
