Please fill the template for new issues, with information about OS, TF version, python version etc. It is very hard to diagnose a problem without the information required on the template (made to be filled, not erased). And check your installation of tensorflow, these errors look like a bad installation.
Carmezim commentedon Mar 15, 2017
@WahabZia Sorry you faced issues trying to run TF. If you installed for GPU support I need you to:
%CUDA_HOME%
is properly set and CUDA and cuDNN DLLs directories are in yourPATH
.MSVCP140.DLL
may be missing in your system.Thanks for filling the issue and feel free to ask any questions or doubts you may still have about TensorFlow.
WahabZia commentedon Mar 15, 2017
Thanks @Carmezim for your kind reply i am using the CPU-only version of TensorFlow . What should i do
Carmezim commentedon Mar 15, 2017
@WahabZia If you are using Python.org distribution and receiving this error is very likely
MSVCP140.DLL
is not installed in your system.So as I provided on step 2, please try installing Visual C++ Redistributable linked above, uninstall then install TF again and let us know if you had progress on it.
WahabZia commentedon Mar 15, 2017
Thanks @Carmezim for the help i have found the dll from the DLLFiles.com
https://www.dll-files.com/msvcp140.dll.html
The import issue is resolved
I also used this command
C:> pip install --upgrade https://storage.googleapis.com/tensorflow/windows/cpu/tensorflow-1.0.0-cp35-cp35m-win_amd64.whl
From this thread
http://stackoverflow.com/questions/42011070/on-windows-running-import-tensorflow-generates-no-module-named-pywrap-tenso
before placing the DLL in System32
And now i am facing this issue when i am sort of trying to validate my installation.

Thanks alot for the help
WahabZia commentedon Mar 15, 2017
Both of the problems are resolved . Thanks gentelmen for the help . The issue was occurring because of missing MSVCP140.DLL which was found on https://www.dll-files.com/msvcp140.dll.html
or by installing Visual C++ Redistributable as recomeded by fellows .
Thanks @Carmezim and @MicaelCarvalho for the help
imamol555 commentedon Mar 19, 2017
I am also facing the same problem(2nd one). I have installed Visual C++ Redistributable but still facing this issue. Please help me out.
imamol555 commentedon Mar 20, 2017
@WahabZia plz help
WahabZia commentedon Mar 22, 2017
Hello @imamol555 sorry for the late reply can you please share the logs . So that i can the reason for the problem . Sorry again for the late reply i didn't check git account for a couple of days .
krishnaputhran commentedon Mar 26, 2017
@WahabZia plz help. You mentioned that you also faced issue 2nd, but probably forgot to mention how you addressed it. As you requested the logs are as shown below. This is same as you mentioned before

appreciate if you can help to resolve this.
Carmezim commentedon Mar 26, 2017
@krishnaputhran If you look up the comments you'll see his issue was due missing the
MSVCP140.DLL
. You can solve it by downloading the Visual C++ Redistributable.But some users had this problem after install with
pip install tensorflow
because of a bug on the wheel and not the missing DLL mentioned. To solve it uninstall TensorFlow, download this nightly build choosing the right version, CPU or GPU, and install with this wheel.krishnaputhran commentedon Mar 26, 2017
@Carmezim thanks for your immediate response and I appreciate that. Yes my issue is solved now. I had to do the following as mentioned above.
fuxiang-chen commentedon May 18, 2017
Indeed,
pip3 install --upgrade tensorflow-gpu
seems to be causing the issue (tested on Win 10), despite installing the Visual C++ Redistributable. Installing via the following command solves the problem: pip install --upgrade https://storage.googleapis.com/tensorflow/windows/cpu/tensorflow-1.0.0-cp35-cp35m-win_amd64.whldwiggles commentedon May 29, 2017
That solved it for me, too. Thanks.

@narendra-7638 Hi, could you try running this script locally and see what it indicates?
There's clearly a missing or misplaced DLL TensorFlow isn't able to locate in your system so it will help pointing that out.
SanaAnsari-SA commentedon Mar 29, 2018
Hi @Carmezim and @WahabZia , I m facing the same issue for installing TF for CPU-only version. I guess i don't need to install CUDA for CPU-only version. I tried using the following
pip install --upgrade https://storage.googleapis.com/tensorflow/windows/cpu /tensorflow-1.6.0-cp35-cp35m-win_amd64.whl
But getting the following error
tensorflow-1.6.0-cp35-cp35m-win_amd64.whl is not a supported wheel on this platform.
Please help. I have downloaded CUDNN-9.1 but i still feel that i don't need it for CPU-only version, SO haven't installed it yet.
I have the MSVC140.DLL in System32 folder. Also added it in PATH environmental variable.
Also I was working on the previous version of tensorflow i.e 1.5.0 and everything worked fine. This problem started wen I upgraded to the latest version 1.6.0 just to avoid warnings
Python : 3.6.4 installed from python.org for 64bit executable
Tensorflow : 1.6.0 using command "pip install --upgrade https://storage.googleapis.com/tensorflow/windows/cpu/tensorflow-1.6.0-cp36-cp36m-win_amd64.whl"
System Windows 7 64-bit
Native pip
Please revert asap.. Thanking you in anticipation
