Describe the bug

TypeError thrown when calling Scaler form gtda.diagrams

To reproduce

When I ran MNIST_ The eighth code block of classificaion.ipynb:

from gtda.diagrams import Scaler
scaler = Scaler()
im8_scaled = scaler.fit_transform(im8_cubical)
scaler.plot(im8_scaled)

Error prompt appeared:
TypeError: Parameter function is of type <class 'numpy._ArrayFunctionDispatcher'> while it should be of type (<class 'function'>, <class 'NoneType'>).
