Command line options for Julia kernels in Jupyter



I haven’t been able to figure out how to specify command line options (specifically, -O3 and --check-bounds=no) for the Julia kernel that Jupyter uses. This would be handy for profiling. Any ideas?


Not sure if this is the official way to do it, but I believe the relevant information is here. I think you can just copy your julia-0.5 kernel folder with a different name, and change the options. IIRC that’s what I did to generate a no-inline kernel:

  "display_name": "Julia 0.4.5 (inline=no)",
  "argv": [
  "language": "julia"


Awesome, thanks so much!
