Install PyTorch on Mac by pip

Overview

Install PyTorch on Mac OS X 10.14.4
Check whether it works.

Environment

Mac OS X 10.14.4 Mojave

Homebrew 2.1.6 (git revision 0d363)
Python 3.7.2
anaconda3-5.3.1
pip 19.1.1

How to install PyTorch

PyTorch official says you can install PyTorch by conda if you already have Anaconda.
But conda may just fetch package which already build, while pip may build package after getting a wheel compatible with installation environment, so performance may differ.
- I'm not so sure. Log may make it clear.
Then, use pip to install PyTorch

$ pip3 install torch torchvision

Check if PyTorch works well.

from __future__ import print_function
import torch
x = torch.rand(5, 3)
print(x)

Result

tensor([[0.7747, 0.9627, 0.1806],
        [0.9219, 0.1319, 0.9026],
        [0.6719, 0.6495, 0.5341],

Check if GPU CUDA is available

import torch
print(torch.cuda.is_available())

If CUDA is not available, result shows below

False

About anaconda

anaconda for python development

I recommend you to install pyenv if you use homebrew, because config file of anaconda without pyenv is the same as that of homebrew and anaconda without pyenv breaks the config file.

Environment
