liblearned_dyn.so uses absolute path for .pt file – Allow Relative Path or Input Argument #16

Closed merdan-9 closed 11 months ago

merdan-9 commented 11 months ago

I've encountered a challenge with liblearned_dyn.so where it seems to open the .pt file using an absolute (global) path. This poses an issue when the project is used across different PCs where directory structures might differ.

Possible Solution: Modify the library to accept the .pt file path as an input argument. Or, implement support for relative paths to ensure the .pt file is located correctly. Any advice or practical solutions would be greatly appreciated!

Hi Merdan,

I see the problem and added the following parameter to L4CasADi, which lets you set the expected relative or absolute path of the models:

Let me know if this solves your problem.

Best Tim
