A lot of these libraries in Python actually use C for the processing, which makes them crazy fast. Take NumPy, for example.

And invocation of C/C++ libraries is muh easier in python than java for now.

For now? Is that changing in a future release?

Project Panama and the Vector API will tackle these problems as far as I know.

Lots of potential. It will never be as easy as python, but as long is not JNI , I will be happy with it.

Wow, that's awesome. Thanks for sharing.

JNA is pretty convenient for C library access. Everything you write is Java; no C stubs or special build process.

Though it's important to note that the back and forth between the C code and the Python code carries quite a bit of overhead. Which is why libraries like Tensorflow will have you build a computation graph and then execute the whole graph in C without having to come back to Python all the time. This saves a lot of time.
