Hello! I'm trying to reinstall some code I made with artificial
intelligence that uses tesseract. I managed to get everything working
(intelligent scanning of minutes so that they are later renamed and moved
to folders) but now I have changed offices and there is another machine.
When trying to install the libraries I get that windows does not recognize
the installation of tesseract. I downloaded it from
https://github.com/UB-Mannheim/tesseract/wiki and tried various versions.
When I put tesseract -v or where tesseract in the command line it tells me
"tesseract" is not recognized as an internal or external command, program
or executable batch file. I tried to edit the environment variable and it
doesn't work either (select the installation path C:\Program
Files\Tesseract-OCR and check that the files are there) try to open
tesseract outside of python, and it opens a window (like a black console)
and closes automatically I also tried to open from pycharm (where I have
the codes) and it gives me this error:
