This looks familiar from the workshop...
What cmake version are you using?
cmake --version
I am using 2.8.12.2.
@japaf How about instantiating the python interactive interpreter and import modena?
$ python
>>> import modena
(I am expecting this to fail)
@henrus
The C stub causing the error is shown below.
pName = PyString_FromString("DoesNotExist"); // Key we wish to access
if(!pName){ Modena_PyErr_Print(); } // handle error if string conversion fails
modena_DoesNotExist = PyObject_GetItem(pDict, pName); // returns NULL on failure
Py_DECREF(pName);
if(!modena_DoesNotExist){ Modena_PyErr_Print(); } // <----- Culprit
Specifically it is the check for "DoesNotExist" in the modules dictionary that returns NULL. This is expected because there is no entry of "DoesNotExist" I believe(?), and therefore the PyObject_GetItem
function should return NULL.
Unexpectedly, however, it works on my laptop. I also tried to "printf" lines in initlibmodena
to ensure that the stub above is actually executed, and indeed it is.
Going to python and trying to import modena from there gives me the same error.
Indeed that section in global.c
gives me trouble. If I comment out those five lines, I can import modena and initialize forward mapping models, but it fails whenever I try to create new model in macroscopic code. Error message:
Error in python catched in 219 of /home/me/opt/Modena/src/src/model.c

import modena
Works for me with d91a44 from substituteModels2
I can confirm that this is resolved, closing it.
This issue appeared on my desktop, but I couldn't reproduce it on my laptop, so it could be caused by interference with yet unidentified program/package. I did try to clone Modena to new directory and reinstall it, I checked that environment variables were set, but it did not help.
Trying to import Modena (e.g., running any
initModels
script) produced:Any idea, what I should try to get it running?
