Using pynrrd to load data gave me a deprecation warning:
/opt/updated-python3/lib/python3.5/site-packages/nrrd.py:267: DeprecationWarning: The binary mode of fromstring is deprecated, as it behaves surprisingly on unicode inputs. Use frombuffer instead
data = np.fromstring(decompressed_data[byteskip:], dtype)
After forking and running your tests, I stumbled upon a second deprecation warning (assertRaisesRegexp vs. assertRaisesRegex).

I updated both. Tests are still running.
