How to install julia 1.7.0 with juliacall 0.4.3?

[943fansi]

I am completely unfamiliar with Julia. Now there is a 1.8.2 version of Julia in the PythonCall directory. I want to use 1.7.0 version of Julia. How do I operate? Can I reinstall JuliaCall and specify the version of Julia?

Julia dependencies are managed by juliapkg. I recommend reading the README to understand how it works.

You can run something like juliapkg.require_julia("=1.7.0") to specify a particular version, or juliapkg.require_julia("~1.7.0") to allow any 1.7.* version. Then restart Python and it will get a compatible version of Julia for you.

If you work in multiple virtual environments (or conda environments) you'll need to do this in each one or else you'll get the default version.

Alternatively, if you have installed Julia yourself already and want to use that, set the environment variable PYTHON_JULIAPKG_EXE (see the README).

Why do you need Julia 1.7 anyway? Julia is backwards compatible, so 1.8.2 should work fine.

Thanks for your reply. The project is opened at https://github.com/markNZed/ARTimeNAB.jl. I used 1.8.2 version and got an error,

It's weird that the package requires 1.7.0 but ok! Is it working for you now?
