Python/Java development on Apple M1 Macs ? ?

[vivek28]

So I am looking to replace my macbook pro.

Has anyone tried installing python/java x86 binaries and respective IDEs Pycharm/Eclipse/IntelliJ on their new M1 Macs ?

I use python for AI tasks.. working with dataframes and plotting in seaborn. I use Java to create/run test for automated software tests.


Do they run fine with Rosetta2 translation? no compile or errors of any kinds ? Pls help.

Python 3 works!

The Intel version works under Rosetta 2 as well

There is a JDK 16 available: openJDK 16 macOS+AArch64

You can just copy the jdk-16+10/ folder to /Library/Java/JavaVirtualMachines/ and then create a softlink to latest.jdk with the command line: sudo ln -s jdk-16+10 latest.jdk

IntelliJ does appear to work under Rosetta 2 as well. It appears to be using OpenJDK 15 (x86_64).

thats cool, but Jenkins to automate builds.. isnt compatible with all Java versions

woah..so this python arm binary itself !!! can you share the url to it. i can see only below versions for 3.9

 

[nkdonut]

I installed it via Homebrew - I think it built it from source

You can get JDK 8 and 11 from Azul - https://www.azul.com/downloads/zulu-community/?os=macos&architecture=arm-64-bit&package=jdk

As others have said, there is a standard 3.8 installation that runs on the ARM platform. Using Rosetta you can install Homebrew and run the x86 version of Python3.x.

I will note that not all development tools work at the moment, even using Rosetta 2. For example, I am unable to go through the installation process for the required tools for React Native.

more LTS versions are coming. I don't know when though. There is a company Azul.com that is going to support Apple Silicon JDKs but I don't see any releases yet. Azul Announces Support of Java Builds for Apple Silicon

I was able to install pyenv and pyenv-virtualenv via Homebrew, but they were not able to install a Python version (tried 3.8.6 and 3.9.0). I stopped using the Python 3 package directly from Homebrew once I started using pyenv and pyenv-virtualenv. Do you use a different virtualenv solution?

I was able to create virtual environments using the preinstalled 3.8.2 (ARM) and Homebrew's 3.9.0 (x86) by using venv.

>> python3 -m venv /path/folder
>> cd /path/folder
>> source bin/activate
(inside env)
>> which python
/path/folder/bin/python

I haven't used Python's built-in venv. Looks like you need to be inside the folder where you created it before you can activate it?

Thanks for pointing out that option.

Looks like you can activate it from outside the folder, that `cd` is unnecessary.

I think venv is the newest option (as of Python 3.3ish?). And it's part of the standard library!

Thanks. Good resource.

Some apps have the jre already included, however it’s x64 then of course. Is there an easy way to force them to use the native arm64 OpenJDK instead?

are you talking about Idea ?

I have always used oracle Java JDKs.. does Azul open jdks works seamlessly ? I heard only difference is of the installer.

I use Java Selenium classes mostly to create/run automated web tests using Junit/testNG frameworks.

Homebrew has been cool.. provinding native ARM python binary. I remember it helped so much in setting up Jupyter notebooks earlier in the day.

Theoretically you now need to purchase a license to use the Oracle JDKs. It's probably only enforced for large business use though. It doesn't look like the Azul JDKs have an installer but I could be wrong. They are easy enough to install without one. Just copy the JDK folder to /Library/Java/JavaVirtualMachines.

So for the Azul JDK11, you unzip zulu11.43.1007-ca-jdk11.0.9.1-macos_aarch64.zip and copy the zulu-11.jdk folder to /Library/Java/JavaVirtualMachines/

You can have multiple JDKs in the JavaVirtualMachines directory but the system will pick up the latest version. If you want to use an older one there is a command line tool that selects between whatever is installed.

To see what JDK is going to be used by default:
/usr/libexec/java_home

To see all of the JDKs available:
/usr/libexec/java_home -V

To set an older JDK:
export JAVA_HOME=`/usr/libexec/java_home -v 11`
# the quotes are backticks meaning execute in place
# the -v 11 chooses JDK11
# the change is temporary for the current session unless you change your .zshrc or .bashrc

Azul is based on OpenJDK, which is and always was free.

Oracle says their own JDK share source code with OpenJDK starting with Java 11, so you should have same implementation if you use Azul zulu11 or Oracle jdk11. Same with later Oracle LTS releases.
