Galileo SDK: ValueError: No API key found. Please set your GALILEO_API_KEY.

TL;DR

Export it in your shell before running your script, or make sure your .env file actually gets loaded by something like python-dotenv before the Galileo import runs. If you would rather set it in code, use the Configuration object: from galileo import Configuration, then set the galileoapikey attribute on Configuration to your key value. The SDK reads the key from the GALILEOAPIKEY environment variable.

The error

ValueError: No API key found

Fix

1. Export it in your shell before running your script, or make sure your .env file actually gets loaded by something like python-dotenv before the Galileo import runs. Expected: You get the expected result; the problem is gone.

2. If you would rather set it in code, use the Configuration object: from galileo import Configuration, then set the galileoapikey attribute on Configuration to your key value. Expected: You get the expected result; the problem is gone.

3. A stale or revoked key gives a 401 at call time instead of this error, so if you see this ValueError the key simply was not visible in the process environment. Expected: You get the expected result; the problem is gone.

4. Re-run the original operation and confirm the error is gone. Expected: no error, normal output.

Why it happens

Fresh install of the galileo Python SDK fails immediately with "ValueError: No API key found. Please set your GALILEOAPIKEY." I have an API key from the Console. Where exactly does the SDK expect it?
