我尝试使用 pip 安装 OCR 和 PyTesseract 来完成我的实习任务。我的 Python 版本是 3.7，我有 MSVC 2019 和 2017（用于我的 CUDA 和 CuDNN）
pip install tesserocr
它给了我错误

对于 PyTesseract，命令如下
pip install tesserocr-2.4.0-cp36-cp36m-win_amd64.whl
错误如下
WARNING: Requirement 'tesserocr-2.4.0-cp36-cp36m-win_amd64.whl' looks like a filename, but the file does not exist
ERROR: tesserocr-2.4.0-cp36-cp36m-win_amd64.whl is not a supported wheel on this platform.
