Closed iosmichael closed 4 years ago

iosmichael commented 5 years ago

I think there is some build issues with the current library on MAC OSX. Once the python library compiled and installed. An error raises when importing the library

Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/g2o.cpython-37m-darwin.so, 2): Symbol not found: __ZN3g2o10HyperGraph12UnassignedIdE Referenced from: /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/g2o.cpython-37m-darwin.so Expected in: flat namespace in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/g2o.cpython-37m-darwin.so

I dont know how to solve this problem. Help will be appreciated.

Your problem is the "Symbol not found: __ZN3g2o10HyperGraph12UnassignedIdE"-part of the message. This problem got already solved by George Hotz in his livestream while he was programming a slam (he named his project twitchslam). For more Information on how to solve this problem look up for issue #1 . It should be the answer. The livestream on how he solved this (your) problem is yet online - you can find it on youtube. It's a 10h stream, your problem is at around 2h40 and takes up to half an hour to solve for him. Hopefully I could help
