Error when using a PackageCompiler sys image in a different container

Hi,

I’m getting the following error when trying to use a system image in a Python 3.8 container (with Julia installed). The system image was built using the Julia 1.4.1 docker image, using PackageCompiler ( incremental=true, cpu_target="x86_46" ).

fatal: error thrown and no exception handler available.

The /buildworker/ directory doesn’t seem to exist.

System information:

Any help would be appreciated.

I ca see that the error happens in the __init__ function in PyCall:

Thanks for getting back to me.

I tested building the package using the Python 3.8 image with a manual installation of Julia and that didn’t have the same problem. Do you know why there is difference between the use of the two images?

I’m guessing this isn’t really a question about PackageCompiler now, more a difference between the containers.
