How to re-train or continue training ?!?!

[thusinh1969]

Hi,

Great stuffs really. I walked through your code a lot, but still not sure how to reload weights to continue training should I terminate in the middle for some reasons.

I edited train.py:
...
if "reload_weight_checkpoint" in self.config.keys() and self.config["reload_weight_checkpoint"]!="":
self.model.load_weights(self.config["reload_weight_checkpoint"])
... right before fit.

--> ERROR:

ValueError Traceback (most recent call last)
in
----> 1 history = trainer.train()

D:\AI\Human_Pose\DeepLabV3-Plus\deeplabv3plus\train.py in train(self)
188
189 if "reload_weight_checkpoint" in self.config.keys() and self.config["reload_weight_checkpoint"]!="":
--> 190 self.model.load_weights(self.config["reload_weight_checkpoint"])
191
192 history = self.model.fit(

~\AppData\Roaming\Python\Python38\site-packages\tensorflow\python\keras\engine\training.py in load_weights(self, filepath, by_name, skip_mismatch, options)
2220 'load_weights requires h5py when loading weights from HDF5.')
2221 if not self._is_graph_network and not self.built:
-> 2222 raise ValueError(
2223 'Unable to load weights saved in HDF5 format into a subclassed '
2224 'Model which has not created its variables yet. Call the Model '

ValueError: Unable to load weights saved in HDF5 format into a subclassed Model which has not created its variables yet. Call the Model first, then load the weights.

Thanks much.
