Install Language Extensions

Note

If you have Machine Learning Services installed on SQL Server 2019, the mssql-server-extensibility package for Language Extensions is already installed and you can skip this step.

Run the command below to install SQL Server Language Extensions on Red Hat Enterprise Linux (RHEL), which is used for the Python custom runtime.

# Install as root or sudo
sudo yum install mssql-server-extensibility

Install Python 3.7 and pandas

The Python language extension used for the custom Python runtime currently supports Python 3.7 only. If you would like to use a different version of Python, follow the instruction in the Python Language Extension GitHub repo to modify and rebuild the extension.

1. Run the commands below to install Python 3.7.

   # Install python3.7 and the corresponding library:
   yum install gcc openssl-devel bzip2-devel libffi-devel zlib-devel
   
   cd /usr/src
   wget https://www.python.org/ftp/python/3.7.9/Python-3.7.9.tgz
   tar xzf Python-3.7.9.tgz
   
   cd Python-3.7.9
   ./configure --enable-optimizations --prefix=/usr
   make altinstall

2. Run the command below to install the pandas package

   # Install pandas to /usr/lib:
   sudo python3.7 -m pip install pandas -t /usr/lib/python3.7/dist-packages
