error trying to regenerate

[gautambak]

Hi Rahul,

Thank you for this wonderful project and I'm excited to play around with it.

If I said regenerate to false, then the code works but when I try to regenerate using my own PDF and data, I get the following error:
ERROR ### Here is the buggy response: None

An error occurred: HTTPConnectionPool(host='localhost', port=11434): Max retries exceeded with url: /api/generate (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7caf1e449180>: Failed to establish a new connection: [Errno 111] Connection refused'))

Hey Gautam,
I think this is because of the missing Ollama server.

when you set regenerate to False, it just reads the existing CSV file. When you set it to False, it tries to re-extract concepts from the LLM. For that, it needs an Ollama server hosted locally and Zephyr model pulled locally.

Step 1: Install Ollama https://ollama.ai
Step 2: run ollama run zephyr in your terminal. This will pull the zephyr model to your local machine and start the Ollama server.

Hey Rahul,

Thank you for that, I'm still getting errors:

I am confused.
Do you have an Ollama server running before you run Ollama pull zephyr

In any case, this problem pertains to the Ollama server on your local. I am sure if it is running properly, the code will run. Please refer to Ollama documentation

[gautambak]

ok i'll try again. I am not running this locally, I'm trying to run it on colab so that might be the problem.

[nestorDario]

Good morning.
I can run in Colab?
How do I use Ollama?
