We need CU3+ with Machine Learning Services and Language Extensions installed. In addition to this we obviously need SQL Server and Python. Reading the steps in the README.md file, we see some requirements: There, (in the root for the Python extension), is also the Python extension source code. When you drill down into the root for the Python extension, there is a README.md file that explains the steps, (those steps are the ones I referred to in the beginning), and what is needed to build the Python extension.
MICROSOFT VISUAL STUDIO 2017 BOOST PYTHON ZIP FILE
In the last post, we downloaded the zip file for the Python language extension, but in this post, we will build from source, so we start with cloning the GitHub repo for SQL Server Language extensions.
MICROSOFT VISUAL STUDIO 2017 BOOST PYTHON CODE
So, to use another Python version than 3.7.x, we need to re-build the existing Python extension, and - as I said above- how hard can that be, the code is open-source after all. However, when we tried to do the same with Python 3.9, we failed, as - as mentioned above - the Python language extension is version bound to Python 3.7.x. That’s how we used another runtime than the one coming with SQL Server. When we run the code, we see 3.7.9 being output. The code in Code Snippet 2 outputs the Python version we execute against, and by setting the parameter to p379, we ensure we use the language we created in Code Snippet 1. To use the newly created language we: EXEC pandas as pdĭf = df.append(, ignore_index=True)
MICROSOFT VISUAL STUDIO 2017 BOOST PYTHON INSTALL
assigned read and write permissions for the SQL Server instance-specific Launchpad service, and the ALL APPLICATION PACKAGES group to the Python install directory.The post has been updated since, and the PYTHONHOME variable is not necessarily needed. created a system environment variable PYTHONHOME pointing to the install directory of Python 3.7.9.after installing Python, we installed the pandas module, as it is not installed by default: pip install pandas.In the post, we looked at using Python 3.7.9, and what we did was:
The language extensions implement the Extensibility Framework API for SQL Server Language extensions are C++ dll’s acting as a bridge between SQL Server and the external runtime. We may want to do this because we want to use a later version of the runtime, for example. This allows us to bring our own R/Python runtime to SQL Server 2019, (CU3+), and use those runtimes in SQL Server Machine Learning Services. So, if you are interested - read on!Īs I wrote in the post mentioned above, Microsoft open-sourced R and Python language extensions in September 2020.
MICROSOFT VISUAL STUDIO 2017 BOOST PYTHON HOW TO
I had read the steps of how to build a Python language extension for Windows here, and it didn’t seem that hard: some Boost, CMake, compile, and Bob’s your uncle! Well, it turned out it was somewhat more complicated than what I anticipated. When I wrote we’d look at it in a future post I thought to myself “how hard can it be?”. NOTE: For R and Java the existing language extension can be used regardless of R/Java version, (at least as far as I know). In the post, I wrote that if you want to bring a Python runtime other than version 3.7.x, (like 3.8, 3.9, etc.), you need to build your own Python language extension, and we’d look at it in a future post. In my post, Bring Your Own R & Python Runtimes to SQL Server Extensibility Framework I wrote about how we can use other R and Python runtimes in SQL Server Machine Learning Services than the ones that come “out of the box”.
I have edited information about the PYTHONHOME system variable, as well as PATH requirements. NOTE: This post has been updated after it was originally published.
