Sudden Termination of Python when importing pinocchio.casadi

[ghost]

The Import failed without any message and python just exit. I can still compile c++ codes with pinocchio. What should I do to debug? It still works days ago.

pinocchio can be normally imported. only pinocchio.casadi is unavailable

On which commit are you working now? What was the former one?

I debugged for a while and found that when import pinocchio.casadi a SX is created with value a tuple (0), which may caused exception. I guess it may use import casadi.casadi instead of import casadi
The casadi version is 3.5. Can you debug see if this happens on your pc? the exception code is about line 9234 in casadi.py in casadi folder, see if the args of init is a tuple zero
Traceback
Wrong number or type of arguments for overloaded function 'transpose'.
Possible prototypes are:
transpose(Sparsity)
transpose(DM)
transpose(SX)
transpose(MX)
You have: '(SX)'

Sorry, but you are hard to follow.
Could you provide a tiny example that is not working on your side in such a way we can try on our side?

Just import pinocchio.casadi. I see Process finished with exit code -1073741819 (0xC0000005)

and it comes to

after line 9238 is excuted, it exits directly

I'm using casadi 3.5.5 and everything works perfectly well.
If it was working well a few days ago, it should remain the case. I suspect some change on your side.

Please consider reinstalling a clean version in a clean environment.
