When using Theano backend, the following warning message was displayed in my Jupyter notebook:
The cuda backend is deprecated and will be removed in the next release (v0.10). Please switch to the gpuarray backend.
The warning message was resolved by completing the following 2 actions:
Action 1. Update Theano config file
- In Linux terminal execute command
sudo nano ~/.theanorc - Update "device = gpu" to
device = cuda0
Action 2: Update Jupyter notebook to include "import theano.gpuarray"
Note that the Cuda backend warning message is no longer displayed.
