Thanks for your advice, however I am using ubuntu on wsl (windows subsystem for linux), and I have already tried to set TESSDATA_PEREFIX by executing $ export TESSDATA_PREFIX=/usr/share/tesseract-ocr/4.00/tessdata/ . But, I cannot use tesseract. If I use the traineddata downloaded from sudo apt install tesseract-ocr-chi-sim, I can use tesseract with the data downloaded from data Data files. Cannot I use tesseract on wsl (Ubuntu)?
