Trying to flatten array in numpy

Question

I'm new to numpy and trying to flatten a 1000,1000 array created from a pandas dataframe. the code i've used is:

    lidor_array=lidor_df.values
    print(lidor_array.shape)
    lidor_array.flatten()
    print(lidor_array.shape)

the shapes are output as (1000,1000) for both the pre and post flattened array. what am i missing?

many thanks for your help

flatten is not performed in-place. It returns a copy:

You could either do:

lidor_array.flatten().shape

or

lidor_array_flat = arr.flatten()
print lidor_array_flat.shape
