How to setup PyTorch on a Mac

Both Mac OS X and Linux are based on the Unix operating system. Therefore your Mac has a pre-installed command-line environment running a shell that is essentially Bash.

• First open the terminal application on your Mac.

• To setup PyTorch:

  • If it's not already installed on your system make sure you have Python 3. Download the correct MacOS installer from https://www.python.org/downloads/mac-osx/ and use it to install Python3.

  • Scroll to the QUICK START LOCALLY part of pytorch.org.

  • Choose Stable, Mac, conda, Python, and None and cut and paste and run each line that doesn't start with # in the Run this command box into your terminal on your Mac. If you find out that you don't have conda installed, change the settings to use pip instead.

    Note: the QUICK START LOCALLY part of pytorch.org might kick out the command

    Copy
    pip install torch torchvision

    Instead, use this

    Copy
    /usr/bin/pip3 install torch torchvision

    See our page Installing Python Packages for more best practice when installing software.

  • Check and see if PyTorch installed successfully by opening the Python interpreter (by entering python3 at the command line) and entering import torch. You shouldn't see an error. (Hit control-d to exit the interpreter.)
