'mk_af_model' object has no attribute 'aux'

'mk_af_model' object has no attribute 'aux', there is no self.aux when aux is none

Can you post the code you are using?

Below is the code, thank! reported above error when run the last line: af_model.save_pdb(save_path)

def rg_loss(inputs, outputs):
      positions = outputs["structure_module"]["final_atom_positions"]
      ca = positions[:,residue_constants.atom_order["CA"]]
      center = ca.mean(0)
      rg = jnp.sqrt(jnp.square(ca - center).sum(-1).mean() + 1e-8)
      rg_th = 2.38 * ca.shape[0] ** 0.365
      rg = jax.nn.elu(rg - rg_th)
      return {"rg":rg}

if __name__ == '__main__':
    pdb_files = ['NavPas_LqhIT2.pdb', 'NavPas_LqhaIT.pdb']   
    data_dir = '/ai/cheng/data/zhongke/cryo-EM-mod'

    for pdb_file in pdb_files:    
        pdb_path = os.path.join(data_dir, pdb_file)
        save_path = os.path.join(data_dir, pdb_file.replace('.pdb', '_repaired.pdb'))

        clear_mem()
        af_model = mk_afdesign_model(protocol="partial",
                             loss_callback=rg_loss, # add rg_loss
                             use_templates=False)   # set True to constrain positions using template input

        if pdb_file == 'NavPas_LqhaIT.pdb':
            af_model.prep_inputs(pdb_filename=pdb_path, chain="A", pos="295,297,300,302,304,320,321,", length=100)
            af_model.rewire(loops=[36])            
            af_model.save_pdb(save_path)

please check the above code

Oh I see what the problem is. You don't run any of the design protocols. The rewire function only sets up the new residue index and constraints, but you still need to run the design protocol to get a sequence that satisfies those constraints.

yes, thanks! I added run the design protocol and it works. but i got a memory issue, the gpu memory had reached 160G unexpectedly. I open a new question regarding the issue. please kindly help to see where is wrong.

Thanks! Closing, as memory is a separate issue.
