cannot declare variable ‘DynaSLAM::g_numpyAllocator’

It seems like an OpenCV version issue. Make sure you are using last version of DynaSLAM #13

Thanks. I've solved this problem.
While I meet another issue when I run
./Examples/RGB-D/rgbd_tum Vocabulary/ORBvoc.txt Examples/RGB-D/TUM2.yaml data/rgbd_dataset_freiburg2_desk_with_person .//Examples/RGB-D/associations.txt ./maskfolder ./output
The terminal shows:
nImages: 3983
Loading Mask R-CNN. This could take a while...
Importing Mask R-CNN Settings...
Segmentation fault (core dumped)
Looking forward to your answer.

What's more, the program can run well without using MaskRCNN
./Examples/RGB-D/rgbd_tum Vocabulary/ORBvoc.txt Examples/RGB-D/TUM2.yaml data/rgbd_dataset_freiburg2_desk_with_person .//Examples/RGB-D/associations.txt

Hi! What versions of Python and OpenCV are you using? Check #19. Maybe it helps.

I've solved it. Thank you so much!

[jmfacil]

Was it a version problem?

[hexu33]

It was because I altered CmakeLists.txt and changed python directory to use python of anaconda, while some mistakes happened. Then I used python of Linux to cmake&make the program, it could compile successfully.

[jmfacil]

That's great :). I will close the thread then.

Thanks for helping.

Hi, I am having the exact same issue, I didn't change the CmakeLists.txt to anything other than use opencv 4.1.1. Any idea what the problem might be in my case? downgrading to opencv3.2 is not an option since jetpack for nvidia xavier agx only allows me to properly install opencv4 now.
