Describe the problem

I was trying to install tensorflow cpu version on windows10, but always got error when import tensorflow.

I read the common_installation_problems , tried many solution I found on github, stackoverflow, etc. I install visual studio 2015, visual studio 2017, Microsoft Visual C++ 2015 Redistributable Update 3(both 32 and 64), msvcp140.dll can find in both System32 and SysWow64 folder. But still can’t import tensorflow.

Is there something I missed out?

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.

run tensorflow_self_check.py result:

ERROR: Failed to import the TensorFlow module.

- Python version is 3.6.

- TensorFlow is installed at: C:\Users\sss\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 'nvcuda.dll'. The GPU version of TensorFlow requires that
  this DLL be installed in a directory that is named in your %PATH%
  environment variable. Typically it is installed in 'C:\Windows\System32'.
  If it is not present, ensure that you have a CUDA-capable GPU with the
  correct driver installed.

- 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.

Seems tensorflow 1.6 is the issue, I installed 1.5 and it works just fine try pip install tensorflow==1.5

Have in mind that downgrading to tensorflow 1.5 might not be the best solution because for instance, you won’t have access to some of the new features of tensorflow like the ‘eager execution’ feature for example.

What i did in my case was to install tensorflow 1.8 with conda instead of pip. From my little experience with conda and pip, conda seems to perform better when it comes to placing required files in their proper location.

In summary, Instead of pip3 install --upgrade tensorflow, i used conda install tensorflow which will install the latest version properly.

In case you don’t have Anaconda installed for conda commands. Download from https://www.continuum.io/downloads

i got this message with tenserflow 1.10.0, solution ?

Open …\Python37\Lib\site-packages\tensorflow\python_pywrap_tensorflow_internal.pyd use Dependency Walker, it will show you the DLL dependency tree, you will find which DLL cause the problem. TensorFlow always linked to the specific CUDA version.

The problem is that I think there is an imcompatibility issue. When installing tensorflow-gpu directly, did not work. I solved the problem as.

First, I created the conda environment as following: conda create -n myenv python=3.6 conda activate myenv Then I installed the keras-gpu=2.2.2 conda install keras-gpu=2.2.2 #this command also installed the tensorflow
