Re: [Jython-dev] developing an IDE for jython

[Yaqiang W. <yaq...@gm...>]

I found Stewori has add a star to JythonLab repository. So I am thinking
again the necessary for providing an integrated Jython package. Readme and
license problem could be sovled by adding more contents or files on them.

Unfortunately, the pip with Jython was not installled succesfully in my
computer that means I can not test the pip ability for packages with java
components.

NumJy is a pure Java solution which is more easy to be used in various
computer systems. I tested the big array multiply speed of NumJy and NumPy
in my computer. At first calculation NumPy is faster than NumJy
significantly, but after, I guess the JIT optimization effect, NumJy even
runs little faster than NumPy. Of course I believe NumPy should be much
faster than NumJy in most other functions. I also mentioned ND4J project
using JNI and native BLAS for high speed, which is valuable to be tried as
an optional backend of NumJy in the future.
