Deserializiation via msgpack fails

[pantaray]

Describe the problem
Running ParallelMap with a function accepting NumPy 2d-arrays as input fails.

Steps To Reproduce

Running

def f(x):
    return x+x

x = np.full([4, 2],1)

n_workers = 3

xinput = [x for _ in range(n_workers) ]

client = acme.esi_cluster_setup(partition="8GBXS", n_workers=n_workers)
with ParallelMap(f, xinput, n_inputs=n_workers) as pmap:
    results = pmap.compute()

reproducibly results in the error

msgpack.exceptions.ExtraData: unpack(b) received extra data.

Turns out this is a bug in msgpack that only affects Python 3.11+

Additional Information
Solution:

conda install -c conda-forge msgpack-python=1.0.5
