int64 error

[BorisMansencal]

The following code does not work:

import numpy as np
from mmappickle import mmapdict

m = mmapdict("/tmp/test.mmdpickle")                                                                                                                                                              
a = np.array(1234, dtype=np.int64)
m['a'] = a

print("type m[a]=", type(m['a']))

I get the following error:

Traceback (most recent call last):
