​@@rizkiananda352why you are expecting to pass?

[@kineticraft6977]

If anyone is having trouble where its running but not actually placing the new files in the output directory, if you followed the github example command, the "--min_length 10000" is whats doing it. It simply goes through that whole process and then decides its too short. Either reduce that number to a much lower number of chars or remove the option entirely. 30 min of hunting through TMP folders for the files and finally figured it out

[@gregsLyrics]

Brilliant vid - it is a godsend. OCRing a PDF is just not workable, period. I gave up on attempting parsing PDF. This new information is amazing and I am once again excited.

[@engineerprompt]

Glad it was helpful!

[@Alvaro-cs7zs]

Thanks for the video. I try it but it did a little bit of a mess with the tables on my PDF. Not working really well. The rest of the text gets resolved properly. But tables, not really, just some of them are nicely structured and done

Thanks for covering Marker, this is brilliant!! Would love to see batch processing of pds using Marker. Also, for the web scraping projects, can we include one, where we scrape data apartment rental data (that keeps changing/evolving) from websites like craigslist, etc. store it persistently in a vetorstore or db and then run a query on that info?

[@engineerprompt]

let me see what I can do.

[@greymooses]

If you do make a video about scraping data, please go over content that requires javascript to load. It’s been difficult to find a clear guide specifically for capturing this data for LLM usage. I loved this video, thank you!

[@engineerprompt]

I haven't look into it before so let me see what I can come up with.

[@anandu06]

How you tried the scanned documents instead of digital pdf? And handwritten text as well?

[@tedp9146]

I actually tried it out today before seeing this video and sadly it produced quite messed up results for a not so complicated document. Some sections and tables were parsed perfectly but even if there are some scrambled up parts the results are useless :/

[@PritiSurange]

in video git repository not mentioned whatever you given in description box

[@Nick_With_A_Stick]

Marker only used 4gb of vram out of a a6000, can you increase the batch size and get some more speed gain? Or is it stuck at that speed regardless of the batch size? 100 seconds per page is a huge improvement over nougat, but still very slow 😢 I love the video tho, I struggled with this one time for hours making a custom script to scrape this one pdf. Definitely gonna use marker sometime soon.

[@engineerprompt]

I think you want to run multiple files in a batch. That will give you the best performance. I also came across megaParse (github.com/QuivrHQ/MegaParse) which is based on top of LlamaParse. That is not 100% local though,

[@Nick_With_A_Stick]

[@mariongully4087]

Very interesting. Once you have converted the pdf file, how can we give all this info to the vectordatabase for RAG ?

[@engineerprompt]

You will do similar chunking like text files. I will put together a video on it.

[@ritikeshchoube1748]

i have pdf of scanned documents it is like images os using tesseract i am converting this into images and then reading it but the thing is my pdf has also some table and when i am generating embedding of this and then passing into to an llm it is unable to answer the question which i am asking from the table...

[@engineerprompt]

My recommendation will be to run them through a multimodal model like Claude Haiku, if cost is not a big concern. You can use that directly to answer questions from scanned docs. Here is a video on how to do that. kzbin.info/www/bejne/l2ayiGiLdt52aac

Hi, do you know how much RAM is required for this application? I tried, but it said that it was out of memory. My laptop has 16 GB RAM w/o Nvidia GPU. Thanks a lot

[@семенантонов-ч7ф]

Is it support pdf files with AMS-TeX / AMS-LaTeX math notation (amsmath)?

[@engineerprompt]

not sure, is the path correct?

[@themorethemerrier281]

This sounds very interesting but I will need to learn some python environment basic before I can put this to the test. A solution like this could help me a lot!

[@jimlynch9390]

It showed some promise except it flaked out with a overflow error. On the pages it seemed to convert it scrambled the data and lost some of it. These pages are primarily transactions in a table with columns separated by whitespace. The pages with plain text worked a bit better.

[@engineerprompt]

interesting, I think it has some limitations. Hope the creator continue working on it. In the tables case, it might be good to use a multimodal model.

[@Naejbert]

Is this suitable for over 250 1mb PDFs?

[@neurojitsu]

Would this work for annotated pdfs? Would it be advantageous to use Marker for NoteboolLM and Anthropic, or is it not necessary?

[@engineerprompt]

If you have PDFs, I would suggest send it to Gemini Flash to convert it into markdown and then feed that to Anthropic.

[@neurojitsu]

@@engineerprompt thank you

[@drmartinbartos]

Around 7minutes, having installed a conda environment you select pip not conda when installing PyTorch - any reason why? If there’s a working conda option doesn’t it make sense to keep using conda and only use pip when you absolutely have to? Just wondering.. (thanks for the video btw - had just been wondering about effective ways of making off content reliably available to RAG and the video is super-useful).

[@engineerprompt]

I usually use pip because that has most of the python packages available. conda is somehow limited with available python packaged. conda will also work in this case but its more of my own habit at this point :)

[@leomeza9396]

Awesome! Thanks for sharing this!

[@intellect5124]

would be interested to learn parse the data from URLs of websites and also query the parsed data using opesource methods. we can call it as web article/new research tool

[@engineerprompt]

Great, idea. Will do that.

[@tanmeshnm]

The main challenge I faced when using nlm-ingestor was parsing SVG images from PDFs. I'm curious whether it will handle this case well.

[@engineerprompt]

Not sure, you might want to look into unstructuredio as well.

[@danielpicassomunoz2752]

Anything to convert to epub? Getting rid of headers and footers

[@ignaciopincheira23]

Could you add the description of each image to the text with the aim of having a single Markdown file, similar to the original PDF? This way, it would be possible to pass a file to a language model that is readable and maintains its content.

[@engineerprompt]

Yes, that is possible. I am going to create a video on multi-modal RAG which will cover this topic.

[@cristian_palau]

thank you for sharing this excelent tools!

[@maxlgemeinderat9202]

Do you think this could be better than unstructuredIO?

[@engineerprompt]

I think this gives you some of the features which are in the premium version of unstructuredio

[@anuraglahon]

If we want to do it for many pdf at once and then build chatbot?

[@engineerprompt]

Yes, there is a batch version. I am going to create an end to end tutorial on it

[@samcavalera9489]

Thanks so much bro 🙏🙏 My question is when your pdf has some images inside, and you want to do embedding on the pdf for the purpose of RAG, how can you pass the info of images to the vector db? Is there any way to do multi-modal RAG? In the case of scientific papers, those images contain significant amount of useful information. Many thanks in advance 🙏

[@engineerprompt]

If you have images, you want to run them through a vision model (such as Llava) to generate their text description and then embed that description in the vectorstore along with the metadata. You can use it directly with RAG then.

[@samcavalera9489]

@@engineerprompt thanks bro for your guidance! For us in academia, using RAG on scientific papers is fruitless without incorporating the figures, as most of the time, figures contain way more information than their mere descriptions in the paper. I will give your suggestion a try and see how I can resolve this problem. Thanks again bro!

[@engineerprompt]

Yeah, I am thinking about it. Will post something.

[@Lowlightu]

Is it better than Unstructured ?

[@engineerprompt]

really depends on the use case and the ability to run this completely local.

[@AdarshMadrecha]

Can you please share GitHub URL of solution you are talking about

[@Larsbor]

I am uncertain about marker, it is for scientific use, but says it removes footers, that is where you normally put in your sources, and apendix links.. so?!

[@anandgs]

Thank you very much!!! I was looking for something like this for a long time. I work for a large bank but with very small budget for my project. Due to budget crunch we cannot afford buying third party tools, this sounds to be a perfect fit but since there is a limit of $5MN we may not qualify to use this for free. Would you suggest going with Nougat or you have a better alternative for my use case, really appreciate your content!

[@engineerprompt]

Nougat can be an option or look into unstructuredio. Also I would recommend to look into Claude or GPT4o with vision if data privacy is not a big issue. Some of these proprietary tools have good data privacy based on their TOS.

[@thunderwh]

Fantastic, thanks!

[@denijane89]

The dumb part of python tools is that ok, you'll install marker, but it will want python=3.10, while the langchain and crewai will work with python=3.11 and as a result you cannot authomize the process because each tool resides in its own conda env. So yeah, I like what I saw, it really looks good, but I'll have to create the markdown separately from all the other stuff I have and that's annoying.
