This test is very occasionally failing on my machine in python 3. In python 3
ndarray.datagives a memoryview object, and thestrof a memoryview is just"<memory at [address of memoryview object]>", so the only reason the test usually works is because the first memoryview gets deallocated and then the second one gets allocated in exactly the same place.bytesgives you the actual underlying data in both 2 and 3.
