Control: tags -1 + patch upstream This issue is caused by the removal of the Python 2 compatibility macros in version 4.5.0 of SWIG. [1] According to the SWIG authors, these macros were retained in the generated code (pyhead.swg) solely for user typemaps. All typemap using these macros are updated to call the Python 3 C API directly.
I submitted a patch for fixing the issue as a merge request at Salsa. [2] Best, Rafael Laboissière [1] https://github.com/swig/swig/commit/79f7a2b7cb7ddc256eba09c8770133148025171d [2] https://salsa.debian.org/science-team/python-fann2/-/merge_requests/3
