I've recently installed ArrayFire 2.1 on my Ubuntu 12.04. I want to use it with Python, is it possible? I tried ArrayFire_Python but it is incomplete, and it does not include functions such as rotate. I have exported the AF_PATH=/opt/arrayfire.
ArrayFire is working well:
1 - I did (at examples/helloworld)
make cuda
2 - Run:
./helloworld_cuda
3 - Get:

The Python bindings of arrayfire are now part of PyPi so you can install them with pip install arrayfire.
