  • When shopping, I like to make it seem extremely likely I am stealing to help poor people who actually need to steal to survive.

    For example, when picking up a soda, I furtively look to my left and right to make sure no one is looking and crouch my head down. I pick up things and make it seem like I may be putting it in a pocket at times before putting it back. When security guards say hi, I don’t make eye contact or reply back and put my head down as if hiding.

    I never actually steal and haven’t ever shoplifted anything.

    I have been kicked out stores many times for abnormal behavior, but never while stealing.











  • That’s exactly what I am trying to do, I’m just not that sure how to do it. I have the hardware needed, I just need to set up a docker with PyTorch and then find a way to set up Gradio inside that and then add TrOCR from hugging face, and then I’m good. I just am not totally sure how to do that and it seems hard, and when I ask AI for advice, it often is like “just run the following” and it’s wrong, and I’m not skilled enough to know why.






  • Terminal error after running GPT code:

    LLMs are so bad at code sometimes. This happens all the time time with LLMs and code for me, the code is unusable and it saves no time because it’s a rabbit hole leading to nowhere.

    I also don’t know if this is the right approach to the problem. Any sort of GUI interface would be easier. This is also hundreds of pages of handwritten stuff I want to change to text.


  • that’s not for TrOCR, it’s just for OCR, which may not work for handwriting

    I did try some of the GPT steps:

    pip install --upgrade transformers pillow pdf2image
    
    

    getting some errors:

    ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━╺━━━━━━━━━ 3/4 [transformers]  WARNING: The scripts transformers and transformers-cli are installed in '/home/user/.local/bin' which is not on PATH.
      Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.
    ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
    mistral-common 1.5.2 requires pillow<11.0.0,>=10.3.0, but you have pillow 12.1.0 which is incompatible.
    moviepy 2.1.2 requires pillow<11.0,>=9.2.0, but you have pillow 12.1.0 which is incompatible.
    
    
    

    this is what GPT said to run, but it makes no sense because I don’t have TrOCR even downloaded or running at all.

    Install packages: pip install --upgrade transformers pillow pdf2image
    Ensure poppler is installed:
    
    Ubuntu/Debian: sudo apt install -y poppler-utils
    macOS: brew install poppler
    
    Execute: python3 trocr_pdf.py input.pdf output.txt
    

    That’s the script to save and run.

  • I don’t remember exactly, but I have rocm 7.2 installed, and there was something I was trying to install inside pip for rocm and it just wouldn’t work, it was like 7.2 rocm wasn’t out or the link didn’t work. The LLM tried multiple suggestion and they all failed, then I gave up. When I said “inside” pip, I don’t know if that’s accurate. I am very knew to pip and am decent at linux and only know a small amount of coding and lack python familiarity.
