WebJan 11, 2024 · The LightningModule liteBDRAR () is acting as a wrapper to your Pytorch model (located at self.model ). You need to load the weights onto the pytorch model inside your lightningmodule. As @Jules and @Dharman mentioned, what you need is: path = './ckpt/BDRAR/3000.pth' bdrar = liteBDRAR () bdrar.model.load_state_dict (torch.load … WebApr 6, 2024 · Currently this can't be achieved without an external bash script that tracks the model evaluation performace and (1) kill the training if loss increased, (2) restart with decayed learning rate. Which is too much work. Let's implement module.restart_from_checkpoint_ (.) for pytorch lightning module.
