4.5 Search

$ pip Search Pycudapycuda                    -Python wrapper for Nvidia cudapyfft                     -FFT library for Pycuda and Pyopenclcudatree                  -Random forests for the GPU using Pycudareikna                    -GPGPU algorithms for Pycuda and Pyopenclcompyte                   -A Common set O F Compute primitives for Pycuda and PYOPENCL (to be created)

4.6 Configuration Files

Configuration files: $HOME/.pip/pip.conf , for example:

[global]timeout = 60index-url = http://download.zope.org/ppix[install]ignore-installed = Trueno-dependencies = yes
