Python: How to convert ndarray to ndarray list

Question

I would like to extract first axis of numpy.ndarray to become a list of numpy.ndarray.

For example, arr_A contains a numpy ndarray with shape (3, 100, 200) which will be converted to a list of numpy ndarray with shape (100, 200) and len(arr_A) is 3.

What is the easiest way to do it?

Many thanks!

You can simply pass the ndarray to the constructor of list:

list_arr_A = list(arr_A)
