Eyes example does not work in JuliaPro 1.2.0-2 (Julia 1.2.0) #168

Open rszoh opened 4 years ago

rszoh commented 4 years ago

I am new to Julia and I really like Mamba. I seem to run into issues when I try to reproduce the Eyes example (https://mambajl.readthedocs.io/en/latest/examples/eyes.html). I get the error message below. I have no clue what is going on.

This looks like an issue in the Distributions package. I've pushed a commit to the master branch with a temporary fix. Use Pkg.develop("Mamba") in Julia to get the fix.

Thank you Brian! This is not working for me. I get the following error:

Pkg.update() to get the latest version of the Distributions and other packages.

Brian, I could not that example to work in JuliaPro 1.4.0 - However, I finally download the barebone Julia 1.4.0 and things work just perfectly. It is still not really clear to me why update and/or develop still does not grab the right update of Mamba in JuliaPro 1.4.0. Thank you
