Keras is available to all users of HPC2N.
Keras is a minimalist, highly modular neural networks library, written in Python and capable of running on top of either TensorFlow or Theano.
Keras was developed with a focus on enabling fast experimentation. Being able to go from idea to result with the least possible delay is key to doing good research.
Use Keras if you need a deep learning library that:
- Allows for easy and fast prototyping (through user friendliness, modularity, and extensibility).
- Supports both convolutional networks and recurrent networks, as well as combinations of the two.
- Runs seamlessly on CPU and GPU.
On HPC2N we have Keras available as a module on Kebnekaise.
To use the Keras module, first add it to your environment. Use:
module spider keras
to see which versions are available, as well as how to load the module and the needed prerequisites.
Note that while the case does not matter when you use "ml spider", it is necessary to match the case when loading the modules.
You can read more about loading modules on our Accessing software with Lmod page and our Using modules (Lmod) page.
Note that if you are running as a batch job, you need to do
srun python .....
since the Keras module is built with MPI.
Note that KERAS_BACKEND is set to theano in the module file, so if you want to use tensorflow instead, you have to set the environment variable to that
More information about Keras, including documentation and getting started guides can be found on the Keras homepage.
