Reproduisez les échecs dans distarray/globalapi/tests/test_distarray.py, en particulier test_mean_dtype, test_var_dtype et test_std_dtype, ainsi que dans distarray/globalapi/tests/test_distributed_io.py pour test_save_load_with_filenames. Suivez les appels à travers distarray/globalapi/distarray.py et distarray/globalapi/context.py, puis vérifiez que ces tests réussissent avec NumPy 1.10 et que le chargement basé sur les noms de fichiers fonctionne.
