AttributeError: module 'keras.utils.generic_utils' has no attribute 'populate_dict_with_module_objects'

Hello everyone, I'm running into this issue

def getGradCAM(X, model, resize_factor=0, layer_maps=-4):
    # Create functions ----------
    # GRAD - backprop
    # create function
    model = guided(model)
    saliency = K.gradients(K.sum(model.outputs[-1]), model.layers[layer_maps].output)
    pooled = K.mean(saliency[0], axis=range(len(saliency[0].shape) - 1))
    grad = K.function([model.layers[0].input], [pooled])

the problem is at the first line, here is the error:
