title: Using NumPy and Cpython with Jython
body: <p>I <em>must</em> use a commercial Java library, and would like to do it from Python. Jython is robust and I am fine with it being a few dot releases behind. However, I <em>would like</em> to use NumPy as well, which obviously does not work with Jython. Options like <a href="http://jpype.blogspot.com/" rel="noreferrer">CPype</a> and Java numeric libraries are unappealing. The former is essentially dead. The latter are mostly immature and lack the ease of use and wide acceptance of NumPy. My question is: How can one have Jython and Python code interoperate? It would be acceptable for me to call Jython from Cpython or the other way around. </p>
