Can I run Keras model on gpu?
Of course. if you are running on Tensorflow or CNTk backends, your code will run on your GPU devices defaultly.But if Theano backends, you can use following 

Theano flags: 

"THEANO_FLAGS=device=gpu,floatX=float32 python my_keras_script.py"
I'm running a Keras model, with a submission deadline of 36 hours, if I train my model on the cpu it will take approx 50 hours, is there a way to run Keras on gpu?
I'm using Tensorflow backend and running it on my Jupyter notebook, without anaconda installed.
