How to pack arrays iwht msgpack on python?

Question

I have a dict of arrays like these:

gen = {0: [array([0])], 1: [array([1]), array([-1])]}

and I would like to save them with msgpack:

import msgpack

with open('data.msgpack', 'wb') as file:
    msgpack.pack(gen, file)

But it returns the error:

TypeError: can't serialize array([0])

What is the problem?

i do not have the reputation to comment, but you don't need to initialize an array using 'array', Just using [ ] is enough.

Said that, you can see a similar code posted by a user here

I actually need to save an array with the first entry 0. Also, I'm doing the same thing as the code you linked to, but I do not have a list of strings, but a list of arrays – SuperCiocia Aug 13 '18 at 14:32
just use _gen = {0: [ [0] ], 1: [ [1], [-1] ] }_ – lucas_7_94 Aug 13 '18 at 14:36
Yeah but I need them to be arrays – SuperCiocia Aug 13 '18 at 14:50
Can I not save arrays at all with msgpack? – SuperCiocia Aug 13 '18 at 14:50
