Python 如何用Pytesseract OCR 辨識影像的字元

1. 到 Github 下載 tesseract-ocr-w64-setup-5.3.3.20231005.exe 來安裝Tesseract。
2. 記錄Tesseract安裝的路徑,預設路徑通常為 C:\Program Files\Tesseract-OCR。
3. 將Tesseract.exe路徑新增到環境變數中

Yolov8 解决 OMP: Error #15: Initializing libiomp5md.dll, but found
- 代碼報錯
- OMP: Error #15: Initializing libiomp5md.dll, but found libiomp5md.dll already initialized.
- OMP: Hint This means that multiple copies of the OpenMP runtime have been linked intograms link. cause incorrect results. The best thing to do is to ensure that only a single OpenMP runtime is linked into the process, eg by avoiding static linking of the OpenMP runtime in any library。 variable KMP_DUPLICATE_LIB_OK=TRUE to allow the program to continue to execute, but that may cause crashes or silently produce incorrect results.
