first test fails

In [1]: import jsonpickle

In [2]: import numpy as np

In [3]: u = np.arange (10)

In [5]: pickled = jsonpickle.encode (u)

In [6]: pickled
Out[6]: 'null'

Numpy uses C extensions.
The best bet is to register a custom handler for u[0].__class__.

If you write one then it would be a good example to have in the source
tree, so do share.

There should be a testcase that demonstrates how to do this.

Have fun,

Oops, I originally said u[0].__class__.

It's u that's not encoding correctly, so the handler should be
registered for u.__class__ instead, namely
<type 'numpy.ndarray'>.

See ExternalHandlerTestCase and its use of UnicodeMixin and
UnicodeMixinHandler in jsonpickle_test.py for an example of
how to do this.
