ValueError: You are trying to load a weight file containing 131 layers into a model with 115 layers.

This error occurs when you are trying to load a weight file that was trained on a model with a different number of layers than the one you are currently using.

To fix this error, you need to make sure that the weight file you are using matches the architecture of your current model. This can be done by either modifying your model to match the number of layers in the weight file or by finding a weight file that matches your model architecture.

If you choose to modify your model, you will need to add or remove layers to match the number of layers in the weight file. Once your model architecture matches the weight file, you should be able to load the weights without any issues.

Alternatively, if you choose to find a weight file that matches your current model architecture, you can search for a pre-trained model that has the same number of layers as your current model. This will ensure that the weights are compatible with your model and can be loaded without any errors.
