Hello, I’m trying to set paraview python variants programmatically (each of them conflicts with the others). I’m not a TCL ninja so I came out with the code below, but I’m getting error of the type: "Warning: Variant python27 conflicts with non-existing variant python35 python36 python37” for all the variant combinations. How do I set variants programmatically?
```
# Supported pythons
set python_versions {27 35 36 37}
foreach pyver ${python_versions} {
# Conflicting python versions
set other_python_versions {}
foreach other_pyver ${python_versions} {
if {${other_pyver} ne ${pyver}} {
if {${other_pyver} ni ${other_python_versions}} {
lappend other_python_versions python${other_pyver}
}
}
}
# Get python branch
set python_branch {[string range ${pyver} 0 end-1].[string index ${pyver}
end]}
variant python${pyver} conflicts [join ${other_python_versions} " "]

"\n Currently Paraview installs as an app, including the Python

${applications_dir}/paraview.app/Contents/Python/:${applications_dir}/paraview.app/Contents/Libraries/
to PYTHONPATH and ${applications_dir}/paraview.app/Contents/Libraries/ to
DYLD_LIBRARY_PATH. Also, simultaneous use of independent vtk libraries, e.g.
with Mayavi, may result in segfault."
