2 • written for non-kdb+ programmers to use • well documented, with understandable and useful examples • maintained and supported by Kx on a best-efforts basis, at no cost to customers • released under the Apache 2 license • free for all use cases, including 64-bit and commercial use • embedPy is part of the Fusion for kdb+ interface collection Fusion interfaces to kdb+
3 • Allows the kdb+ interpreter to manipulate Python objects and call Python functions. • Python functions can be called from q, and q functions can be called from Python. embedPy programmers q/kdb+ programmers embedPy embedPy gives direct access to data in kdb+ embedPy offers easy access to the numerous computational and visualization libraries
5 • Loads Python into kdb+, allowing access to a rich ecosystem of libraries such as: • Python variables and objects become q variables – and either language can act upon them • Python code and files can be embedded within q code • Python functions can be called as q functions embedPy
6 Execute Python code directly in a q console or from a script, by prefixing the Python code with p) q)p)print(1+2) 3 You cannot run multi-line Python code directly in the console, but you can add to a q script using the syntax below. p) and subsequent lines indented according to usual Python indentation rules, for example: $cat testScript.q a:1 p)def add1(arg1): return arg1+1 embedPy
7 To run a q script with embedded python code, simply load the script into your q session: q)\l testScript.q q)p)print(add1(12)) 13 To run a Python script, rename the file from file.py to file.p and load in the same way as above: $cat helloq.p print(“Hello q!”) q)\l helloq.p Hello q! embedPy
8 Jupyter kernel for kdb+. Features include • Syntax Highlighting for q • Code completion for q keywords, .z/.h/.Q/.j namespace functions, and user defined variables • Code help for q keywords and basic help (display and type information) for user defined objects • script like execution of code (mulit-line input) • Inline display of charts created using embedPy and matplotlib • console stdout/stderr capture and display in notebooks • Inline loading and saving of scripts into and from notebook cells jupyterq
10 Machine-learning capabilities are at the heart of future technology development at Kx. Libraries are released under the Apache 2 license, and are free for all use cases, including 64-bit and commercial use. EmbedPy forms the basis of machine learning initiative at Kx Machine Learning
12 There are three packages that you can install from https://anaconda.org/kx • kdb (non-commercial personal edition, requires internet connection to work) • embedPy • jupyterq Setup kdb, embedPy and juypterq TIP: installing jupyterq will automatically install the embedPy and kdb packages
