2 years ago The issue is fixed for Windows on a separate branch (fix-java-vm). Unfortunately, the differences in multiprocessing between Linux and Windows lead to failing tests in the CI pipeline for the Linux builds. I cannot properly debug this at the moment, so for now the proposed solution is to clone the version from the fix-java-vm branch in case you need to restart the Java VM in any downstream tasks.
Currently, the Java VM cannot be restarted after it is shut down. This limitation can be avoided if we run all tasks that require the VM in a separate process using the multiprocessing module: https://github.com/LeeKamentsky/python-javabridge/issues/88 This would also allow us to run many causal discovery procedures in parallel. A downside is that the start of a new process adds additional overhead that will affect the runtime of an analysis.
