TypeError: Object of type Tag is not JSON serializable

[richlysakowski]

When loading URLs I get this error message. I tried just loading the ThinkRAG webpage.
I got this same error with other webpages.

I am running ThinkRAG locally on Windows 10 Pro, Ollama, Llama3 LLM.

I tried fixing the code after these two errors, but I have not fixed it yet. I will post and synch the solution if I can get it working on my local installation.

Have you resolved this issue on Windows?

[richlysakowski]

Not yet. Nothing has been done on this in > 2 months and there is no support for Windows.
I gave up and moved on to other RAG applications. It looks like the project is DEAD.

I will wait until there is renewed activities by the project owner or other developers who have forked it and are actively fixing and extending it for Windows. Was this an academic demo?

The goals and concepts are nice, but it must implement everything with conda and Windows to have a large audience. Mac-only or Linux-only support is too academic, not mainstream.
