  How to run .py in KX Developer

  Posted by evol on October 24, 2022 at 12:00 am

  Hi community

  My problem is:” I can’t open .py in KX Developer.”

  error: embedPy must be loaded to evaluate Python code

   

  My version in Conda base env

  kdb 4.0

  embedPy 1.5

  jupyterq 1.1.13

  python 3.9.12

   

  that’s my terminal code for q

   

   

  that’s my code for Kx developer

   

   

  So, how can I fix it?

  thanks all

   

  Can I use python to call a q database? Or using q to compute python data in the same dialog box?

  Have you installed embedpy?

  https://code.kx.com/q/ml/embedpy/#build-and-install

  Can you load and test it?

  \l p.q 
  p)print(1+1)

  It’s work, thanks

  Also, I have 3 questions

  01/ just like before python code, I download data from ibapi api

  I can use q insert to q databases ? in the same dialog box or not ?

  Can you give a simple example of Q and PYTHON  code

  02/ or use python to select data from q databases to trade?

  03/ What’s different about embedPy and PYQ?

  thanks

  There are useful comparisons on this page: https://code.kx.com/pykx/1.3/comparisons.html

   

  You can expose python function to q using embedpy

  You can do it all in a q file or as I like to do split out to a .py and a .q

  Such as: https://github.com/rianoc/qXML

   

  kdb+ can also use websockets natively if needed

    you’re encountering an issue with running Python scripts in KX Developer due to the embedPy module not being loaded.

    To resolve this issue, you need to ensure that embedPy is properly loaded in your KDB environment. You can do this by adding the following line to your q script before attempting to run any Python code:

    \l embedPy.q

    This line loads the embedPy module, allowing you to evaluate Python code within your q environment.

    Once embedPy is loaded, you should be able to run Python scripts in KX Developer without encountering the error you mentioned.

    Regarding your question about using Python to call a q database or vice versa, yes, it’s possible to integrate Python and q. You can use embedPy to call Python functions from q or vice versa. This allows you to leverage the strengths of both languages within the same environment.

    Thank you
