Some objects in Python have no attribute 'measured' #1142
Description
Description
Hi, I am using the python wrapper of GTSAM. I cannot get measured() from the RangeFactor2D and BearingFactor2D objects. I can get it from the BearingRangeFactor2D object. Any clues for potential solutions? Is there a different way to access the measurements in those factors in Python? Thanks!
Steps to reproduce
import gtsam
if __name__ == "__main__":
try:
br_f = gtsam.BearingRangeFactor2D(1, 2, gtsam.Rot2(.3), 10.0, gtsam.noiseModel.Isotropic.Sigma(2, 1))
print(br_f.measured())
except Exception as e:
print(str(e))
try:
range_f = gtsam.RangeFactor2D(1, 2, 10.0, gtsam.noiseModel.Isotropic.Sigma(1, 1))
print(range_f.measured())
except Exception as e:
print(str(e))
try:
bearing_f = gtsam.BearingFactor2D(1, 2, gtsam.Rot2(.3), gtsam.noiseModel.Isotropic.Sigma(1, 1))
print(bearing_f.measured())
except Exception as e:
print(str(e))Expected behavior
bearing : 0.3
range 10
'gtsam.gtsam.RangeFactor2D' object has no attribute 'measured'
'gtsam.gtsam.BearingFactor2D' object has no attribute 'measured'

I looked into the declaration of objects RangeFactor2D and BearingRangeFactor2D navigated by my PyCharm IDE. I did see measured() in the BearingRangeFactor2D.py.
