Why this sequential model is not starting?

I am using following code: 



input_shape = (75, 75, 3)
x = Input(input_shape)
model = BatchNormalization(axis = 3)(x)


Above code works all right. However, following code does not work: 



input_shape = (64,64,3)
model = Sequential()
model = model.add(InputLayer(input_shape=input_shape))
model = model.add(BatchNormalization(axis = 3))


But at last line, I get error: 



AttributeError: 'NoneType' object has no attribute 'add'


If I change to: 



model = model.add(Input(input_shape))


I get following error: 



TypeError: The added layer must be an instance of class Layer. 
Found: Tensor("input_1:0", shape=(?, 64, 64, 3), dtype=float32)


Where is the problem and how can it be solved?

It is a team of 2: just I and my supervisor. Diurnally, I am posed with a "bug of the day" to get out of this C++ code. My supervisor generally gives me about 15-30 minutes to solve it and then accosts me about whether or not the task is completed and then rinses and repeats this until the end of the day.

This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of
