PAISS18

NLE practical session for PAISS 2018

Installation

Linux / MacOS

First, download and install the appropriate version of miniconda following the instructions for MacOS or Linux.

Then run the following commands:

conda install numpy matplotlib ipython scikit-learn
conda install pytorch torchvision faiss-cpu -c pytorch

On MacOS there’s a bug for faiss related to libomp (facebookresearch/faiss#485): run “brew install libomp” (see https://brew.sh/ to install brew) to resolve this bug.

Windows

Install anaconda on windows (launch .exe file downloaded from the conda website). It has to be python 3 (pytorch doesn’t support 2.7 on windows)

In the anaconda prompt, run:

conda create -n pytorch
activate pytorch
conda install pytorch-cpu -c pytorch
pip install torchvision --no-deps
conda install pillow
