You can install skimage with pip.

@kxhit , thanks for your answer, after you suggestion, i run Check.py file correctly, but when i run dyna-slam, it show the same segment fault too

i use anaconda to create a new env, and python version is 3.6, but why here still get python2.7.so??? confused

Current version of the code runs with Python 2.7 (line in the code) , we plan to update it to 3.X but the code is not fully tested yet.
It does not matter if you work on a virtual env with python3.x the code seeks for python 2.7 specifically.

@jmfacil , hi, jmfacil,
thanks for your replaying, i understand use libpython2.7.so in cmakelists.txt, and code can find it, but my code still run error with segment fault?? and i can run orb-slam2 code correctly before when i use opencv 3.3.1, i am confused about where wrong happened?

Hi there,
Do you get same segment fault?
First, make sure you are using last version of DynaSLAM #13.
Second make sure all dependencies are correctly installed for python2.7

@jmfacil , yes, i git clone the last version of DynaSLAM , about python 2.7, it is installed along with system, so i don't konw the meaning of dependencies for python2.7. cause using mask-rcnn, i install python 3.6 in a new env by anaconda, and installed tensorflow and keras like readme says, and i can run check.py correctly, thanks again for you nice reply!!!

Hi! No problem!
Dependencies like numpy, tensorflow ... should be installed on python2.7 as is the version DynaSLAM will be using. Mask-rcnn will be executed by the program with python2.7. I would recommend you create another env but this time with python 2.7. And then install dependencies there. I didn't try with virtual env yet so maybe you need to make sure paths to python libs are correct. Check CMakeList.txt
Another option would be to install dependencies on the python 2.7 installed with the system. Then changes in cmake and code should be minimal.
Hope it helps!

@jmfacil , thanks , i change my python version into 2.7 follow your advice, and i install dependencies needed by mask-rcnn. i run check.py, it result correct. and i compile the dynaslam, build sucessfully. but when i run code, it show about bus error, different from before error:

In #16 they suggest to change to OpenCV 2.4.11 instead of 3. Maybe you can try that.
