Uploading third-party Python packages to Snowflake

Note that this guide is specifically for notebooks running on a warehouse.

See here for when running a notebook on a container runtime.

1. Create a stage

If yo want to use a Python package within a notebook running on a warehouse and it's not available via Snowflake’s Anaconda channel of pre-approved packages you’ll need to use a stage to upload the source code of the Python packages you want to use.

1. Install Python via Anaconda

https://www.anaconda.com/download

2. Initialise conda into your shell

For Powershell:

conda init powershell

import snowflake.connector

value = None

# Won't work:
f"""INSERT INTO example_table(
            visitors
            ) VALUES
            (
            '{value}',
