" ImportError: DLL load failed: The specified procedure could not be found"- while Digit Recognition using CNN in Python using Keras

Question

I am trying to write a simple character recolonization code using convolutional neural network in python on windows. I am following this tutorial. But somehow I am having following error message. I could not find the appropriate reason of this error. It would be helpful for me if anyone can breakdown the error with probable solution.

    Using TensorFlow backend.

Answer 1

Check if you have installed CUDA, CUDNN, added them to your PATH variable, and if you have correct versions of them for your Tensorflow version (each Tensorflow version supports only range of CUDA versions), check for example this tutorial for installation. Also, I guess you try to install it on windows (based on the DLL error), which is quite important to mention.
