Pyramech Mac OS
Current Instructions¶
Unfortunately, the Pytorch team does not release binary package for Mac OS with CUDA support. This project provides off-the-shelf binary packages. Both Python 2.7 and 3.7 are supported now! 很不幸，Pytorch团队不发布 Mac OS CUDA版。. PyTorch is a Python package that provides two high-level features: Tensor computation (like NumPy) with strong GPU acceleration Deep neural networks built on a tape-based autograd system You can reuse your favorite Python packages such as NumPy, SciPy and Cython to extend PyTorch when needed. Download the latest version of PyCharm for Windows, macOS or Linux.
Create and add the following to ~/.bash_profile:
# Homebrew binaries now take precedence over Apple defaults
export PATH=/usr/local/bin:$PATH
Install Apple Xcode command line tools:
xcode-select --install
Install XQuartz: http://xquartz.macosforge.org/landing/
Install homebrew:
ruby -e '$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)'
Install Python3 'proper' and packages we’ll need for installing PyGame from bitbucket:
brew install python3 hg sdl sdl_image sdl_mixer sdl_ttf portmidi
Install PyGame:
pip3 install hg+http://bitbucket.org/pygame/pygame
Restart the Mac for XQuartz changes
Old Instructions¶
(UPDATED) How to install pygame for Mac os Sierra Python 2.7(UPDATED)
Mac OS X comes with Python 2.7 out of the box.
You do not need to install or configure anything else to use Python 2. Theseinstructions document the installation of Python 3.
The version of Python that ships with OS X is great for learning, but it’s notgood for development. The version shipped with OS X may be out of date from theofficial current Python release,which is considered the stable production version.
Doing it Right¶
Let’s install a real version of Python.
Before installing Python, you’ll need to install GCC. GCC can be obtainedby downloading Xcode, the smallerCommand Line Tools (must have anApple account) or the even smaller OSX-GCC-Installerpackage.
Note
If you already have Xcode installed, do not install OSX-GCC-Installer.In combination, the software can cause issues that are difficult todiagnose.
Note
If you perform a fresh install of Xcode, you will also need to add thecommandline tools by running xcode-select--install on the terminal.
While OS X comes with a large number of Unix utilities, those familiar withLinux systems will notice one key component missing: a package manager.Homebrew fills this void.
Pyramech Mac Os Update
To install Homebrew, open Terminal oryour favorite OS X terminal emulator and run
The script will explain what changes it will make and prompt you before theinstallation begins.Once you’ve installed Homebrew, insert the Homebrew directory at the topof your PATH environment variable. You can do this by adding the followingline at the bottom of your ~/.profile file
If you have OS X 10.12 (Sierra) or older use this line instead
Now, we can install Python 3:
This will take a minute or two.
Pip¶
Homebrew installs pip pointing to the Homebrew’d Python 3 for you.
Working with Python 3¶
At this point, you have the system Python 2.7 available, potentially theHomebrew version of Python 2 installed, and the Homebrewversion of Python 3 as well.
will launch the Homebrew-installed Python 3 interpreter.
will launch the Homebrew-installed Python 2 interpreter (if any).
will launch the Homebrew-installed Python 3 interpreter.
If the Homebrew version of Python 2 is installed then pip2 will point to Python 2.If the Homebrew version of Python 3 is installed then pip will point to Python 3.
The rest of the guide will assume that python references Python 3.
Pipenv & Virtual Environments¶
The next step is to install Pipenv, so you can install dependencies and manage virtual environments.
A Virtual Environment is a tool to keep the dependencies required by different projectsin separate places, by creating virtual Python environments for them. It solves the“Project X depends on version 1.x but, Project Y needs 4.x” dilemma, and keepsyour global site-packages directory clean and manageable.
For example, you can work on a project which requires Django 1.10 while alsomaintaining a project which requires Django 1.8.
