Hi, I am trying to launch a Julia Kernel with a few packages in mybinder. The build fails due to overshooting the memory limit. I want to add the following command line option to the kernel install “–heap-size-hint=1G” to force garbage collection once the specified heap limit is reached.
I tried creating a postbuild file with the following lines of code –
using IJulia
installkernel("Julia heap size limit", "--heap-size-hint=1G")
Is this the right way to do it? If not, what is the correct way to do it?
During the build process, I see the following command being run by the binder to install the kernel. The command does not include the options in the postbuild file.
/bin/sh -c JULIA_PROJECT="" julia -e "using Pkg; Pkg.add(\"IJulia\"); using IJulia;
installkernel(\"Julia\", \"--project=${REPO_DIR}\");" && julia --project=${REPO_DIR} -e 'using Pkg;
Pkg.instantiate(); Pkg.resolve(); pkg"precompile"
postbuild is a shell script that runs after everything else:
There’s no way to pass additional arguments to Julia, so I think your best option at the moment is to setup a minimal Julia environment using the standard repo2docker configuration files, and use postBuild to install the additional Julia packages that are taking up too much memory.
