I am trying to install intel optimized pytorch in different ways

Question

I am very first time using pyTorch. I am trying to install it. In how many ways I can do this? Please provide the steps for that.

Answer 1

You can install PyTorch in 3 ways.

1. Using pip
2. Using conda
3. From source

1.Intel Optimized Pytorch Installation

Install the stable version (v 1.0) on Linux via Pip for Python 3.6.

pip install https://download.pytorch.org/whl/cpu/torch-1.0.1.post2-cp36-cp36m-linux_x86_64.whl

pip install torchvision

2.Conda Pytorch Installation

conda install pytorch-cpu torchvision-cpu -c pytorch

3.PyTorch Installation from source

Create a new environment:

conda create -n <env_name> python=3.6

export CMAKE_PREFIX_PATH=/home/user/.conda/envs/<env_name> 

source activate <env_name>   

Install dependencies:

conda install numpy pyyaml mkl mkl-include setuptools cmake cffi typing

conda install -c conda-forge opencv

conda install Pillow

Get the PyTorch source:

git clone --recursive https://github.com/intel/pytorch

cd pytorch

mv caffe2/contrib/cuda-convnet2/ /tmp       
# Fix the bug removing the old package out

Install PyTorch:

python setup.py install 2>&1 | tee build.out

Hope this will help you.
