Error when de-serializing dictionary containing numpy arrays

[e0en]

The code below causes error:

import numpy as np
import msgpack
import msgpack_numpy as m
m.patch()


dict_np = {"np": np.zeros((3, 4)), }
packed = msgpack.packb(dict_np)
unpacked = msgpack.unpackb(packed)  # this will cause error

The code above will cause a KeyError because the decode function in msgpack_numpy tries to decode the dictionary dict_np as a serialized version of numpy array.

Wrapping the entire content of decode function with try-except clause will solve this issue. More specifically, modify the code below:

def decode(obj):
    blah_blah

like this:

def decode(obj):
    try:
        blah_blah
    except KeyError:
        return obj
