This library works natively on M1 Macs due to the fact that our DyNet wrapper includes native support for M1 processors starting with version 0.4.1.
To install one (or more!) Java Virtual Machines (JVM) on Macs we recommend sdkman. The steps to follow (instructions by Gus Hahn-Powell) are the following:
# install sdkman from source:
curl -s "https://get.sdkman.io" | bash
# open a new terminal window and run the following:
source "$HOME/.sdkman/bin/sdkman-init.sh"
# test your installation:
sdk version
You can configure sdkman using the following command:
sdk config
which should open ~/.sdkman/etc/config in your default editor.
For M1 processors, you want to only list ARM64-compatible versions. To this end, alter the following config entry in the config file:
sdkman_rosetta2_compatible=false
Open a new terminal and try listing ARM64-compatible versions of java:
sdk list java
To install an ARM64-compatible distribution of Java 11 via sdkman, run the following:
sdk install java 11.0.14-zulu
This version should also work with Intel machines.
To install sbt and scala, run the following commands:
# sbt 1.6
sdk install sbt 1.6.1
# scala 2.12
sdk install scala 2.12.15
