Python example api error

[Geek0x0]

I encountered some problems while running the python example

CaydynMacbookPro:faiss caydyn$ python python/demo_auto_tune.py
load data
load GT
prepare criterion
Traceback (most recent call last):
File "python/demo_auto_tune.py", line 73, in
crit.set_groundtruth(None, gt)
File "/Users/caydyn/Development/faiss/python/swigfaiss.py", line 2053, in set_groundtruth
def set_groundtruth(self, *args): return _swigfaiss.AutoTuneCriterion_set_groundtruth(self, *args)
TypeError: AutoTuneCriterion_set_groundtruth() takes exactly 4 arguments (3 given)

CaydynMacbookPro:faiss caydyn$ python ./python/demo_ivfpq.py
loading database
Traceback (most recent call last):
File "./python/demo_ivfpq.py", line 43, in
gt_index.add(xb)
File "/Users/caydyn/Development/faiss/python/swigfaiss.py", line 1143, in add
def add(self, *args): return _swigfaiss.IndexFlat_add(self, *args)
TypeError: IndexFlat_add() takes exactly 3 arguments (2 given)

How to deal with such mistakes?

Hi

This seems to be related to the SWIG wrapper. Could you check which swig version you are using?

swig -version

then restore the machine-generated files from the ones provided in the repo, see
