Opened this issue · 5 comments

Hello,

I am trying to train shapenet data (.obj + .mtl format) but the code requires .mat format.

Is there any converting script missing or have I downloaded the wrong dataset?

Thanks.

Thank you for your reply.

Can you share the code or the method of adding labels and categories ? I'm stuck in the data now.
