Message from CRAN after submission :

Please add \value to .Rd files regarding exported methods and explain the functions results in the documentation. Please write about the structure of the output (class) and also what the output means. (If a function does not return a value, please document that too, e.g. \value{No return value, called for side effects} or similar) Missing Rd-tags in up to 11 .Rd files, e.g.: complex.default.Rd: \value default.math.fun.Rd: \value install_rkeops.Rd: \value ...

You have examples for unexported functions. Please either omit these examples or export these functions. Examples for unexported function arithmetic.multiply.LazyTensor() in: check_keopscore.Rd *.ComplexLazyTensor() in: check_pykeops.Rd check_pykeops() in: fix_variables.Rd check_rkeops() in: get_inner_dim.Rd Arg.default() in: identifier.Rd atan2() in: preprocess_reduction.Rd ifelse() in: set_pykeops_build_dir.Rd ifelse.LazyTensor() in: set_pykeops_verbosity.Rd Im.LazyTensor() in: setup_pykeops.Rd

\dontrun{} should only be used if the example really cannot be executed (e.g. because of missing additional software, missing API keys, ...) by the user. That's why wrapping examples in \dontrun{} adds the comment ("# Not run:") as a warning for the user. Does not seem necessary. Please replace \dontrun with \donttest. Please unwrap the examples if they are executable in < 5 sec, or replace dontrun{} with \donttest{}.

Please fix and resubmit.
