Export/Import GPG Keys
Code Block | ||
---|---|---|
| ||
gpg --export-secret-keys -a xxx@apache.org > ~/Downloads/keys.asc gpg --import /tmp/keys.asc #list the keys to make sure they are there. gpg --list-keys #you will need this to enter your gpg-key password sudo apt install gnupg-agent |
Build MXNet backend on OSX
Clone MXNet repo and checkout the release branch
Code Block | ||
---|---|---|
| ||
export YOURFORK=whatever export RELEASE_VERISON=1.2.0 git clone https://github.com/$YOURFORK$/incubator-mxnet git remote add upstream https://github.com/apache/incubator-mxnet git fetch upstream $RELEASE_VERSION && git checkout -b $RELEASE_VERSION --track upstream/$RELEASE_VERSION |
Install necessary libraries
Code Block | ||
---|---|---|
| ||
brew install lapack brew install openblas |
Build MXNet Backend
Code Block | ||
---|---|---|
| ||
#This will build the MXNet backend with the tested configuration for publishing MXNet-Scala to Maven. scala-package/dev/compile-mxnet-backend.sh osx-x86_64-cpu ./ |
Maven Publish
Follow Maven Publish Link https://www.apache.org/dev/publishing-maven-artifacts.html to setup repo settings, etc., before you proceed
Code Block | ||
---|---|---|

#if you don't set this it will fail with the error "gpg: signing failed: Inappropriate ioctl for device" export GPG_TTY=$(tty) #make sure everything is working as expected make scalarelease-dryrun # Releases to Apache Snapshot make scaladeploy # Verify that the package has been uploaded in https://repository.apache.org/content/repositories/snapshots/ # Preparing the release will create the new tag, automatically checking in on your behalf.(We have disabled CheckIn) make scalarelease-prepare # this will upload to the staging repository and make it ready for closing make scalarelease-perform |
Build MXNet backend on Linux-CPU
To build for linux-cpu platform, we use the AWS Deep Learning Base AMI that comes built with all the necessary
libraries such as opencv/cudnn etc,.
Install Maven on Ubuntu
Code Block | ||
---|---|---|
| ||
sudo apt-get install -y maven |
Debugging Info
Code Block | ||
---|---|---|
| ||
git push --force --delete ./ refs/heads/mxnet-parent_2.11-1.2.0
git tag -d mxnet-parent_2.11-1.2.0 |
If you face an issue because of gpg such as ```Enter passphrase: gpg: gpg-agent is not available in this session```
Code Block |
---|
sudo apt-get install gnupg2 sudo mv /usr/bin/gpg /usr/bin/gpg.1 sudo ln -s /usr/bin/gpg2 /usr/bin/gpg |
gpg: signing failed: Inappropriate ioctl for device
```export GPG_TTY=$(tty)```
Note: compiling with USE_SIGNAL_HANDLER throws a segmentation fault on both OSX and Linux platforms
