@agibsonccc hi, did you manage to find time to look at the code? ---

@ajmakoni so a few things in your project: You need to add the new cudnn backend support specifically. See: > **[Cudnn](https://deeplearning4j.konduit.ai/multi-project/explanation/configuration/backends/cudnn#using-cudnn-via-nd4j)** > > Using the NVIDIA cuDNN library with DL4J. Remove the old deeplearning4j-cuda and ensure that you either have a compatible version of cuda installed or you use the cuda redist artifacts if you won’t have the version of cuda and cudnn installed locally. See: > **[Javacpp](https://deeplearning4j.konduit.ai/multi-project/how-to-guides/developer-docs/javacpp#redist-artifacts)** > > DL4J and Javacpp Based on what I’m seeing in the project a lot of the basic steps are missing for the upgrade. Start there and let me know how it goes. ---
