numpy.ma.load() fails on files generated bu numpy.ma.dump() in python3. See the following code:

from __future__ import print_function
import sys
import numpy as np

print("Python version:", sys.version)
print("Numpy version:", np.version.full_version)

mma = np.ma.ones((4,4))
mma.dump("mma.dat")

mmb = np.ma.load("mma.dat")

And now let's run it:

laptop:~/py/Varie/testNPdump$ python testMAdump.py 
Python version: 2.7.12 (default, Nov 20 2017, 18:23:56) 
[GCC 5.4.0 20160609]
Numpy version: 1.13.3

Now with python3:

lfini@lfini-laptop:~/py/Varie/testNPdump$ python3 testMAdump.py 
Python version: 3.5.2 (default, Nov 23 2017, 16:37:01) 
[GCC 5.4.0 20160609]
Numpy version: 1.13.3
Traceback (most recent call last):
  File "testMAdump.py", line 11, in <module>
    mmb = np.ma.load("mma.dat")
  File "/usr/local/lib/python3.5/dist-packages/numpy/ma/core.py", line 7868, in load
    return pickle.load(F)
  File "/usr/lib/python3.5/codecs.py", line 321, in decode
    (result, consumed) = self._buffer_decode(data, self.errors, final)

AFAICT, this doesn't work in Python 2 either, check the load result. IIRC, there has been some discussion about removing those masked array functions.

Discussion is at #10045

This is a duplicate of #5491, so we should continue discussion there.
