Even bigger speeds ups with CUDA section doesn't work with Anaconda 4.2.0
Hi, I'm trying to learn CUDA python and found this example. I'm using the latest anaconda but the last section doesn't work. I've been unable to figure out how to update it using the Continuum documentation. Would you be able to give any pointers?
Thanks
