the problem when running examples with python

[nsgcjdsz]

I'm very sorry to bother you, but this problem has slowed down my working progress for a long time, I have successfully compiled and connected the python interface in tmr, but I still get an error when running examples with python, which has not been solved for a long time. The example I ran is /home/xy/git/tmr/examples/crank, and l use python 3.5.2, Could you please give me some suggestions?
here is the error information:
Traceback (most recent call last):
File "crank.py", line 3, in
from tmr import TMR
ImportError: /home/xy/git/tmr/tmr/TMR.cpython-35m-x86_64-linux-gnu.so: undefined symbol: _ZTI17Adaptor2d_Curve2d
