If I run

    import pandas as pd
    import mpld3
    import seaborn as sns
    df = pd.DataFrame([(1,3),(2,-1)],columns= ['a','b'])
    plt.figure(figsize=(5,5))
    sns.regplot('a', 'b', df)

works fine. If I add

    mpld3.enable_notebook()

I obtain error: Object of type 'ndarray' is not JSON serializable

Do you have any suggestion about what is causing this annoyance with mpld3?

For what I can understand, this is not the same question asked in NumPy array is not JSON serializable In my question I'm asking how to make mpld3 work or at least not making everything else not working.

Did you solve this? I am getting the same error. BTW this is definitely not a duplicate question.. – João Abrantes Mar 12 '18 at 15:09

Hi @JoãoAbrantes I've not solved it, I just decide to avoid mpld3 for good – Carlo Mar 25 '18 at 18:48

This is not a duplicate question, since we can't access the serializer. – brienna Apr 16 '18 at 21:21

You can find a solution at https://github.com/mpld3/mpld3/issues/441 which consists of class NumpyEncoder replacement – Claude COULOMBE May 19 '19 at 05:44
