TypeError: 'NoneType' object is not callable

I've built the environment by running the script install_all.sh and successfully run main_vo.py. But got TypeError: 'NoneType' object is not callable when running main_slam.py. Need Help! Please check the error below:

Hi there, may I ask how did you end up solving this issue? Really appreciate that if there is some hint/clue, thank you in advance for your time.

I solved it by building thirdparty/orbslam2_features
