Hi, I’m a new WandB user and I’m trying to integrate WandB with my keras tuner in order to keep track of my hyper parameter tunning. I tried to follow an online guide I found but I’m getting errors when I try to load the models with the tuner.get\_best\_models() function **NotFoundError: Unsuccessful TensorSliceReader constructor: Failed to find any matching files for DAM\_Aggr\_tuning\_129\_cc/DAM\_Aggr\_tuning\_129\_cc\_project/trial\_2/checkpoint** Here I leave a link to my colab notebook, anyone that can help it would be really appreciated, I feel stuck… > **[Google Colaboratory](https://colab.research.google.com/drive/1RIqFRqmDMg48KF64ZkzN1BDLNx1y_fef?usp=sharing)** ---

Thank you very much! Let me also provide you with a link to my github folder in case that can help you more. There is the full code suposed to be working along with the data i’m trying to use. > **[WandB/HUB at main · iaioanno/WandB](https://github.com/iaioanno/WandB/tree/main/HUB)** > > main/HUB ---

Hi @johnioanno , I verified that this error is not attributed to wandb. You are creating a python subclass, `MyTuner(kt.Tuner)` to customize the Keras tuner base class `BaseTuner`, see [here](https://github.com/keras-team/keras-tuner/blob/a45341c940e33abb4940a10bad4886f3cb66e88e/keras_tuner/engine/base_tuner.py#L34) for source, and you intend to save the model within this subclass. You must define the `save_model` method, see [here](https://github.com/keras-team/keras-tuner/blob/a45341c940e33abb4940a10bad4886f3cb66e88e/keras_tuner/engine/base_tuner.py#L208) within you subclass. Otherwise you do get the `NotImplementedError` reminding you to implement it. This impacts your ability to load a model(s), resulting in the `NotFoundError` exception. Hope this helps you to move forward with your implementation. Please do reach out again if you run into errors while logging with `WandbCallback()`. Regards, Mohammad ---
