If Pymacs based auto-complete shall be used make sure the directory is in your load-path. In case `Pymacs’ was installed via ‘make’ on your system, don’t activate inlined one. Keep ‘py-load-pymacs-p’ nil.
Otherwise setting ‘py-load-pymacs-p’ to ‘t’ should enable a company-based auto-completion - alongside with ‘py-company-pycomplete-p’.
On systems which run Python3 as default setting export PYMACS_PYTHON=python2 was reported being useful. Newer Pymacs should not need this.
