Mxnet

Installation

  1. Ensure you have correct GPU drivers. Install nvidia for ARCH Linux. Otherwise you won't be able to use GPU.
  2. Use the correct flags and compiler. Refer to the mxnet AUR PKGBUILD for the correct command
  3. Don't need to copy the libmxnet.so manually. python setup.py build|install will package the so file and put into the correct path.
