TypeError: string indices must be integers

[HichemAK]

When trying this example code given for RegNet models:

#RegNetY600
model = get_model(model_name="RegNet",input_shape=input_shape,n_classes=n_classes,
                verbose=True,fc_activation=fc_activation,stage_depth=[1,3,7,4],
                stage_width=[48,112,256,608],stage_G=16,SEstyle_atten="SE")

This error shows up:

31 x = img_augmentation(inputs)
32 #RegNetY600

In the file model_factory.py line 91:

    elif model_name in regnet_parameters.keys():
        model = RegNet(verbose=verbose, input_shape=input_shape,
        n_classes=n_classes, dropout_rate=dropout_rate, fc_activation=fc_activation,
       stage_depth=regnet_parameters[model_name['stage_depth']],stage_width=regnet_parameters[model_name['stage_width']],\
stage_G=regnet_parameters[model_name['stage_G']],SEstyle_atten=regnet_parameters[model_name['SEstyle_atten']],**kwargs).build()

We could try to replace regnet_parameters[model_name['stage_depth']] by regnet_parameters[model_name]['stage_depth'] and do the same for the remaining arguments, but another error, then, occurs:
