Error importing tensorflow on windows 10 ( Tensorflow 0.12.0 RC0, python3.5 )

[akrai48]

Was excited to try out 0.12.0 RC0 for windows
Followed Tensorflow 0.12.0 RC0 Installation guide for Windows, on Windows 10.
Ran into following error.

you should not try to import tensorflow from its source directory;
please exit the tensorflow source tree, and relaunch your python interpreter
from there.

[mrry]

I'm sorry that it didn't work out of the box. Can you answer a couple of questions for me?

1. How did you install TensorFlow? Did you use pip install tensorflow or pip install https://storage.googleapis.com/tensorflow/windows/cpu/tensorflow-0.12.0rc0-cp35-cp35m-win_amd64.whl (or some other command)?

2. Can you run the following command and reply with its complete output?

dir C:\Users\hp\AppData\Local\Programs\Python\Python35\Lib\site-packages\tensorflow\python\_pywrap_tensorflow.pyd

[akrai48]

1. I used pip install https://storage.googleapis.com/tensorflow/windows/cpu/tensorflow-0.12.0rc0-cp35-cp35m-win_amd64.whl as mentioned at https://www.tensorflow.org/versions/r0.12/get_started/os_setup.html#pip-installation-on-windows

2. Here's the complete output:

I'd would like to add that I have both version of python 2.7, 3.5 installed. I hope that's not the issue.

[mrry]

It sounds like it has installed correctly, but one of the dependencies is missing. According to dumpbin, the extension has the following dependencies:

• KERNEL32.dll
• WSOCK32.dll
• WS2_32.dll
• SHLWAPI.dll
• python35.dll
• MSVCP140.dll
• VCRUNTIME140.dll
• api-ms-win-crt-runtime-l1-1-0.dll
• api-ms-win-crt-heap-l1-1-0.dll
• api-ms-win-crt-utility-l1-1-0.dll
• api-ms-win-crt-stdio-l1-1-0.dll
• api-ms-win-crt-string-l1-1-0.dll
• api-ms-win-crt-math-l1-1-0.dll
• api-ms-win-crt-convert-l1-1-0.dll
• api-ms-win-crt-environment-l1-1-0.dll
• api-ms-win-crt-filesystem-l1-1-0.dll
• api-ms-win-crt-time-l1-1-0.dll

Can you check that all of these files are on your system? It's possible that our development and test environment gets one of these from the build tools, and they aren't available as standard.

[mrry]

We've just been able to reproduce the same error, and it was caused by a missing MSVCP140.dll. (Thanks @wolffg!) Installing the Microsoft Visual C++ 2015 Redistributable Update 3 (x64 version) should fix it. Can you please try that and let us know if it works?

[akrai48]

@mrry , worked like a charm. Thank you very much for the effort.

[nvdanh81]

@mrry 👍 Thanks very much!

[DonquixoteMzt]

Thanks~~

[cloud-370]

@mrry , thank you.
your advise(installing Microsoft Visual C++ 2015 Redistributable Update 3 (x64 version) ) also work for native pip3 install tensorflow 1.0.1 on windows10.

[goodluck-hojae]

Thanks alot

[chichur]

Thanks bro

[Randolph-zeng]

@mrry Sorry to bring this up again, I have the same issue as poster. I have been debugging this for several days but no luck. Any advice will be greatly appreciated!

I did lack all of the api-ms-win-crt-*.dll files and python35.dll specifically(I am running in a virtual env of python3.5 in anaconda). I downloaded all the dll files online and add it back to C:\Windows\SysWOW64 but the problem still persists.

I am using Python 3.5.3 |Continuum Analytics, Inc.| (default, Feb 22 2017, 21:28:42) [MSC v.1900 64 bit (AMD64)] on win32.

My Cuda version is 8.0 and the driver is in v6.0, I have added the cuDNN files to my PATH, which is C:\Users\rando\cudnn-8.0-windows10-x64-v6.0\cuda

My gpu is gtx-1080 and below is the error message:

[Randolph-zeng]

@Carmezim Plz help, any advice will be greatly appreciated! Thanks a lot!

[YuriWerewolf]

Same issue here, TensorFlow works with CPU but not with GPU (Nvidia) on Windows 10

[YuriWerewolf]

You need to use cuDNN v.5.1, not version 6.0. Everything works for me after i have replaced v6.0 with v 5.1

[Carmezim]

@Randolph-zeng you shouldn't use cuDNN 6.0, according to TensorFlow requirements only 5.1 is supported on Windows.
For more information please see:
https://www.tensorflow.org/install/install_windows#requirements_to_run_tensorflow_with_gpu_support

[Randolph-zeng]

@Carmezim @YuriWerewolf Hi thanks for the answer, but I still can't get it to work.
I have the tensorflow cpu version working and I am pretty sure this is a problem of cuda now.
I have Cuda toolkit v8.0 and cuDNN v5.1 in my computer and I believe the path is correct.
Is there any other things I can look into? Thanks a million!
My path variable looks like this(with cuda related being the first several lines):

[Carmezim]

@Randolph-zeng I cannot really tell only by looking at your %PATH%. If you're sure cuDNN DLLs are properly set as CUDA's it's not CUDA/cuDNN related.
Is your TensorFlow 1.1? You don't need both installations as well, CPU and GPU, I get it if you were just testing though. Maybe it would be better if you opened a new issue filling the template to better assess what can be happening. This problem usually yields from misconfigured CUDA/cuDNN as you said CPU works. TensorFlow team is working on improving this error message #9170.
You can notice by looking on this issue that is likely to be a missing CUDA/cuDNN DLL from your %PATH%.

[Randolph-zeng]

@Carmezim Okay, I will open a new issue. Thanks for the help! Have a great night!

[ianuzzi]

I'm having a similar problem. I tried rolling back to C++ Redist. 2015 (from 2017) and still not working.

[GitHubKay]

I'm not sure if someone will look in here cause it's "closed". Anyway, i've the same issue. I installed TensorFlow-GPU:
1.) install anaconda 3.6
2.) conda install python==3.5
3.) pip install tensorflow-gpu
4.) Install CUDA 8.0
5.) Install cuDNN

I checked the import tensorflow as tf in my Jupiter Notebook and it worked.
The next day i did the same to follow first instructions with tensorflow
(Btw, i'm new to python, if someone has a good overview over all the packages and extensions as well as good tutorials... i'm more than pleased to here from you).
Anyway, i got the same error that @ianuzzi has. I followed the instructions above but without any change.

Thx for you help guys
Kay

[mrry]

For users who find this issue when searching for the error message, I've created a script for diagnosing common TensorFlow on Windows installation issues. Please download the script from https://gist.github.com/mrry/ee5dbcfdd045fa48a27d56664411d41c and run python tensorflow_self_check.py. It will print suggestions for how to fix your installation. Let me know if you are still facing problems after running the script.

[dakshj]

@mrry Thanks for your script! Worked for me.
My issue was that the PATH for cuDNN was set to D:\TensorFlow\cudnn-8.0-windows10-x64-v5.1\cuda, but the correct PATH for it was D:\TensorFlow\cudnn-8.0-windows10-x64-v5.1\cuda\bin.

[alphashuro]

@mrry thank you your script is very helpful, why don't you submit a pull request to add this script to the tensorflow library itself, so that it can be used as an install step?

[mrry]

@alphashuro I'm glad it helped! Eventually we'll want to integrate some of the heuristics in the script into the import process, but I wanted to get something out there ASAP to help people who were struggling with these problems :). (One slight issue with integrating it in the repository is that we'd like it to be usable for people who haven't managed to install the library correctly....)

[BattleCisco]

@YuriWerewolf @Carmezim Thank you, I installed 6.0 and wondered why it didn't work, uninstalling 6.0 and installing 5.1 worked for me.

Thanks for the help, stay awesome 👍

[zhenglilei]

@YuriWerewolf @Carmezim Thank you, I installed 6.0 and wondered why it didn't work, uninstalling 6.0 and installing 5.1 worked for me.

[XRarach]

This is maybe a very stupid mistake but might help someone... I downloaded just CUDA 8 patch from the site and was wondering, why the error. Apparently, the patch does not care if you have CUDA 8 already installed, it just copied the dll and creates the intermediary directories, even looks like Cuda is installed in installed applications.

[prdas31]

Okay. Solved it. Same issue as TensorFlow 1.3 or later requires cuDNN 6. ('cudnn64_6.dll')

[hisham-hy1508805]

@prdas31 Thank you ... I solved my issue.
I have TensorFlow 1.3, upgrading to cuDNN 6 instead of v5.1 solved the issue
@mrry your script is awesome ... was very helpful for me

[aenciso]

@mrry best script ever! Thanks. I spent hours debugging, reinstalling, etc. You have save my day. Thanks a lot.

[carlhuth]

I wanted to bring up an anomaly that occurred with pip that was causing the No module named '_pywrap_tensorflow_internal' error to occur. The version of python I was running was Python 3.6.3, pip was version 9.0.1. and it was running on Windows 10.

**Using version 1.3.0 (newest of versions: 1.2.0, 1.2.1, 1.3.0) Looking up "https://pypi.python.org/packages/bf/d4/80197f48f9fb90a17c47cdd834b2f13d5f714f26e8ed5c77069d57aa3ecb/tensorflow-1.3.0-cp36-cp36m-win_amd64.whl" in the cache** Current age based on date: 67543 Freshness lifetime from max-age: 31557600 The response is "fresh", returning cached response 31557600 > 67543 _Using cached tensorflow-1.3.0-cp36-cp36m-win_amd64.whl_ Downloading from URL https://pypi.python.org/packages/bf/d4/80197f48f9fb90a17c47cdd834b2f13d5f714f26e8ed5c77069d57aa3ecb/tensorflow-1.3.0-cp36-cp36m-win_amd64.whl#md5=3a7dbe9a17d806e43d2e71b3ddb0cd52 (from https://pypi.python.org/simple/tensorflow/)

The installation command was pip3 install --upgrade tensorflow, which on first run appeared to be working perfectly fine, however that was not the truth. I discovered 3 weird occurrences:

1. The site-package that was downloaded had a METADATA stating it was for Python 2.7. (This obviously was not going to work if it was for the wrong version of Python.) Also, the TensorFlow version was 1.3 instead of the most current 1.4.0rc0 that was expected (verified this by going directly to pypi.python.org site directly).

2. Upon uninstalling the package, I noticed it had saved a cached instance of the package under my user profile as well, which it did not remove when uninstalling the package. That was found in C:\Users**{AccountName}**\AppData\Local\Tmp\Pip-{unique generated id for cached application} and also removed.

3. After removing the cached modules, I again ran the command but with the verbose argument set: pip3 install --upgrade -v tensorflow
   This was assumed to be something that would download the correct version of tensorflow now, but instead it decided that it couldn't find a compatible version of TensorFlow for my Python version 3.6.3 (which I assume the minor rev number may have thrown off the basic logic for acceptable versions, ex. 3.5, 3.6). I again looked at the package metadata for the server-side cached copy of the module and again saw that this was really limited to Python 2.7 again. Which means the server was returning an invalid python package that python 3 could not run, all while saying it was it was the newest version available, which was definitely not true.

The solution was quite simple, I added a forced version number to match the most current version's name, which ran seamlessly and resolved the import error described above.

pip3 install --upgrade -v tensorflow==1.4.0rc0

I have seen this error occuring in Tensorflow 1.4.0 as well because either cuDNN or CUDA toolkit DLLs being of wrong version or found in Anaconda folder instead of NVidia's folder. I've written a blog post on how to debug this error:

@mrry I wasted ample time before coming to this page. I was trying cpu installation of TF. It got resolved after installing visual c++. Thanks much for help.

i tried the selfcheck.py and the report is as follows:

ERROR: Failed to import the TensorFlow module.

I am stuck since hours but the issue is still not resolved.
I am using only the CPU version and getting the same No module named 'pywrap_tensorflow_internal' error ::

I have similar problem. I have a previous version of python 2.7 so I downloaded 3.5.4 Next I installed tensorflow using pip3 install --upgrade tensorflow The message:

Installing collected packages: setuptools, numpy, six, markdown, wheel, protobuf, werkzeug, tensorboard, grpcio, gast, astor, absl-py, termcolor, tensorflow

When trying to confirm installation i get:

What steps can I take from this point on to troubleshoot this issue?

Thank you.

[Walt3r1]

After looking into this problem over few days I came across information that any tensorflow version that is >1.5 will not work with window. So my problem is solved. I downgraded to to 1.5. It's working. If you think this will help you then uninstall any previous version of TF and install the 1.5 version using this command:

pip3 uninstall tensorflow
pip3 install --upgrade --ignore-installed tensorflow==1.5

[tsotsotso]

this was very helpful @Walt3r1 ,to the point and quicker.

[nateGeorge]

@Walt3r1 where did you find this information? To me it looks like any version on windows should work: https://www.tensorflow.org/install/source_windows

[docrainbox]

Could not even run the basic example after installing Tensorflow 1.10.0 with pip install command. Thanks to the suggestion here -- Installing the Microsoft Visual C++ 2015 Redistributable Update 3 (x64 version) -- problem was fixed and able to work with Tensorflow with Spark now.

[ihtisham0331]

I'm sorry that it didn't work out of the box. Can you answer a couple of questions for me?

1. How did you install TensorFlow? Did you use pip install tensorflow or pip install https://storage.googleapis.com/tensorflow/windows/cpu/tensorflow-0.12.0rc0-cp35-cp35m-win_amd64.whl (or some other command)?
2. Can you run the following command and reply with its complete output?

dir C:\Users\hp\AppData\Local\Programs\Python\Python35\Lib\site-packages\tensorflow\python\_pywrap_tensorflow.pyd

i run the above command it show error "The system cannot find path specified
