[FIXED] FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\PAVANS~1\\AppData\\Local\\Temp\\tess_rwsvvy4k.pdf'

Issue

My Requirement

I have generated an exe from python code using pyinstaller. Since I am using pytesseract.image_to_pdf_or_hocr OCR operation Tesseract is the dependency. So I have added tesseract folders in spec file and generated the exe. My aim is to bundle tesseract folders inside the exe itself, so that tesseract folders will be copied in Temp files when I open the exe.

What have I done so far

I have successfully generated the exe from python code. When I open the exe the bundled tesseract files will be extracted to temp files directory and I can start using the tesseract.

Issue

Generally when we run pytesseract.image_to_pdf_or_hocr it will create a pdf (i am passing extension='pdf' parameter) in temp folder with some random name tess_rwsvvy4k.pdf. This works when I run code directly. But when I am running exe, it is not generating the pdf file in temp folder.

Guide me in the right direction...

Solution

Actually, I made a small mistake in spec file. Original tessdata\configs folder contains 25 files and tessdata\tessconfigs folder contains 6 files. But due to my mistake I got only 5 files in tessdata\configs folder. So I missed dependencies for hocr. So in my case I could not able to generate pdf.

My Mistake

('Source/TESSEERACT-OCR/tessdata/configs/*.*', 'TESSEERACT-OCR/tessdata/configs'),
            
            ('Source/TESSEERACT-OCR/tessdata/tessconfigs/*.*', 'TESSEERACT-OCR/tessdata/tessconfigs')

What I have changed

('Source/TESSEERACT-OCR/tessdata/configs/*', 'TESSEERACT-OCR/tessdata/configs'),
            
            ('Source/TESSEERACT-OCR/tessdata/tessconfigs/*', 'TESSEERACT-OCR/tessdata/tessconfigs')

So this will add all the files from the tessdata\configs and tessdata\tessconfigs folders. And I have got my desired output.
