Warning: AMICI ERROR: in module CVSLS in function cvKLUSetup : A call to an external package failed. #444

thomassligon commented 6 years ago

I am sometimes getting this error. Why should a call to an external package fail, unless there is an error in compiling the mex? But that reported no errors.

How can I debug the problem? Do need a more verbose amiwrap report, or do I need to debug the mex executable?

Error during simulation: Warning: AMICI ERROR: in module CVSLS in function cvKLUSetup : A call to an external package failed.

Report after amiwrap: Warning: AMICI does not officially support Microsoft Visual Studio Compilers. If the compilation fails, we recommend using MinGW.

I have experienced the same issue and if I remember correctly, this is error indicates that the factorization via KLU failed. I do not have any good advice on how to fix this issue, but it should only happen for particular parameter values.

thomassligon commented 6 years ago

OK, I'll assume that the error message doesn't mean what it says, but instead that KLU factorization failed. Thanks for the help.

FFroehlich commented 6 years ago

The message does mean what it says, KLU is an external package and the call to a function in that external package failed, i.e., threw an error.
