While trying to validate the installation of tensorflow-gpu, I get an ImportError when trying to execute "import tensorflow as tf". I am using a Quadro K620 on Windows 7. Tensorflow was installed using pip.

The following is the stack trace:

I have looked at multiple other stack overflow posts which things like correcting the path but I have not been able to solve this issue. This post was edited by Laksh Nath at September 5, 2020 3:54 PM IST

I came across the same issue today, please switch to cuDNN v5.1 Library for Windows instead as @mickdelaney suggested and then try to

1. Check environment settings of CUDA, normally all the settings of CUDA had been added to Windows environment
2. Copy files in bin, lib and include of cuDNN to bin, lib and include of CUDA respectively. Normally the directory is C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA

And then you can import tensorflow and run your code. Good luck!

I found the solution for the CPU: It worked for me

Just run below command if necessary then update it

pip install tensorflow==1.5

you could uninstall the current version of tensorflow and try a low version such as TensorFlow 0.12 using the code

pip install --upgrade https://storage.googleapis.com/tensorflow/windows/cpu/tensorflow-0.12.0rc0-cp35-cp35m-win_amd64.whl

After you install the CUDA Drivers you must download cuDNN and release it. After that you get to copy the cudnn64_5.dll to PATH.
If that doesn't work, move the cudnn64_5.dll to NVIDIA GPU Computing Toolkit\CUDA\v8.0\bin and try it again. Otherwise you'd meet some error that you see.

I had the same error with anaconda, it was previously installed with another program through anaconda. Installing again through conda-forge worked:  conda install -c conda-forge tensorflow
