┌ Warning: CHOLMOD version incompatibility
│ 
│ Julia was compiled with CHOLMOD version 4.0.4. It is
│ currently linked with version 5.2.1.
│ This might cause Julia to terminate when working with
│ sparse matrix factorizations, e.g. solving systems of
│ equations with \.
│ 
│ It is recommended that you use Julia with the same major
│ version of CHOLMOD as the one used during the build, or
│ download the generic binaries from www.julialang.org,
│ which ship with the correct versions of all dependencies.
