add support for self hosting

[Marlon154]

Support for pix2tex docker image as backend. Simply run the container activate and set the url in the Obsidian settings to get started.

Thank you for your submission @Marlon154 !

I will look into the code and test tonight, could you add some information to the README on how you run the docker container for pic2tex or link to their documentation?

[Hugo-Persson]

I meant change the README.md, not adding a README.html

[Marlon154]

sorry, selected to wrong file for the commit.

@Marlon154 how are you running the docker container? I am getting the error

I run the container just with

docker pull lukasblecher/pix2tex:api
docker run --rm -p 8502:8502 lukasblecher/pix2tex:api

Are you on a ARM CPU?

Yes @Marlon154 , I am on M3 pro

[Hugo-Persson]

I could try Linux later, but would nice to be able to run on my M3 Macbook Pro

[Hugo-Persson]

@Marlon154 I ran pic2tex directly without docker but I only get

INFO:     127.0.0.1:61521 - "POST /predict HTTP/1.1" 307 Temporary Redirect

My options look like this:

With the url: http://127.0.0.1:8502/predict

How have you configured your settings?

[Marlon154]

Seems like you have different ports. Also the final '/' is relevant (http://localhost:8502/predict/).

[Hugo-Persson]

Nice the end / fixed it for me @Marlon154, I am going to add check for it. Great job with the feature, it works great for me!
