There is an issue in Python 2.7.13 where _ctypes.LoadLibrary no longer accepts Unicode objects. This will be patched in 2.7.14, but for now users should downgrade to 2.7.12 to use the nidaqmx package.

Its mid-2017 and I'm not seeing much chatter about Python 2.7.14.

For nixnet we had the following problems

We found that just removing unicode_literals was sufficient to get nixnet working in all 2.7 versions without any downsides.

See ni/nixnet-python#129

Fix Issues 1 and 32
65ca065 
<rev> Fixing incorrect property data type metadata in the Python DAQmx
API. Raised by issue: #32
<priv> Turns out a number of UInt64 properties had incorrect metadata. I
went through all of the U64 properties in the API and found some others
that were wrong too.

<rev> Working around issue:
#1, where nidaqmx doesn't
work on Python 2.7.13 because of a ctypes bug.

<rev> Changing to install from pypi for nidaqmx_src since installing
from Build Services package dependencies seems broken in newer versions
of pythonservices. We have a requirements file to enforce versions, so
who cares.
