alpaqa's Issues
pip install broken?
Using vanilla `pip install alpaqa' installs alpaqa version 0.0.1 successfully. However, that distribution does not seem to work with the documented examples from the site, in particular the HangingChain MPC. Seems to me the python API is broken/missing...could not import the alpaqa.minimize function, nor the class it wraps.
Using the --upgrade --pre flags does fix this issue. Is there a reason that a version 0.0.2 is not yet released with whatever changes fixed this?
bugs
when i installed c++ version of alpaqa in windows and linux system, there were many bugs. i have tired many times, but i still can not install it. i think there are many aspect that can be improved.
Windows Compilation

Running the problem fails with stack smashing detected
While running the example mpc bicycle problem alpaqa results in stack smashing detected
(env) aditya@aditya-desktop:~/workspace/alpaqa/examples/mpc/python/bicycle$ python3 bicycle-obstacle-avoidance-mpc.py
*** stack smashing detected ***: <unknown> terminated
Aborted (core dumped)
NOTE: The example file has some syntax error, so I had to fix that.
I tried reinstalling alpaqa but that doesn't help
(env) aditya@aditya-desktop:~/workspace/alpaqa/examples/mpc/python/bicycle$ pip3 install --force alpaqa

Casadi with other ipot seems to be working fine.
