Install bug

[uahic]

Hi there,

during installing toppra for Python (Ubuntu 18.04, python 2.7) I get the following error (I can reproduce this error also in my docker containers on other machines)

➜  catkin_ws pip install toppra

I recommend you to switch to python 3. If not, clone the repo and install it from source. The error you have is easy to fix but you may have subsequent ones.
