I have installed cuda toolkit 10 with Visual Studio 2017 and cudnn v7.4.2. Have set the environment variables. My GPU is GeForce RTX 2080 with driver version 417.35. I also have Anaconda installed. My aim is to run Keras library functions using GPU support. I first installed Keras from CRAN, then ran the install_keras(tensorflow=‘gpu’) function. When I test with a small neural network model, I get this error, “ERROR: ImportError: Could not find “cudart64_90.dll” . Tensorflow requires that this DLL be installed in a directory that is named in your path environment variable. Download and install CUDA 9.0 from (link)”
Any guidance will be very appreciated. I have been doing this installation for a month now.
