Memory errors

When running python run.py -m fit -o ./sign0.h5 on B4.002 I got a memory error:

Traceback (most recent call last):
  File "run.py", line 164, in <module>
    main(sys.argv[1:])
  File "run.py", line 161, in main
    args.models_path, dataset.discrete, features)
  File "/aloy/home/mduran/myscripts/chemical_checker/package/chemicalchecker/util/preprocess/script.py", line 54, in save_output
    raws = np.zeros((len(keys), len(orderwords)), dtype=np.int8)
MemoryError

We need to think of ways of not having to load full matrices into memory.
