FAQ: What is the most effective way to convert between casadi.DM and torch.tensor (pytorch) other than using numpy in between?

The simplest way to convert variable u:

casadi.DM(u.detach().numpy())

There is a low overhead buffer API to evaluate CasADi Functions from Python here:

FAQTODO write up how to use that.
