PyTorch

The PyTorch website describes the library as

Tensors and Dynamic neural networks in Python with strong GPU acceleration.

Setup PyTorch on CSD3

• load a recent python and the pytorch dependencies:

  $ module load cuda/9.0 intel/mkl/2017.4
  $ module load python-3.6.1-gcc-5.4.0-64u3a4w py-numpy-1.12.1-gcc-5.4.0-cjrgw2k py-matplotlib-2.2.2-gcc-5.4.0-6oe6fph
  $ module load py-virtualenv-15.1.0-gcc-5.4.0-gu4wi6c
  

• create and activate a virtual environment:

  $ virtualenv --system-site-packages ~/pytorch-env
  $ source ~/pytorch-env/bin/activate
  

• install pytorch into your virtual env:

  $ pip install http://download.pytorch.org/whl/cu90/torch-0.4.0-cp35-cp35m-linux_x86_64.whl
  $ pip install torchvision
  $ pip install kiwisolver
  

• download and run an example program:

  $ wget https://pytorch.org/tutorials/_downloads/cifar10_tutorial.py
  $ python cifar10_tutorial.py
  

Running a PyTorch program

PyTorch will be able to run on both CPU and GPU.
