我正在尝试使用以下命令在 Ubuntu 16.04 上为 python 3.5 安装“tesserocr”模块
pip3 install tesserocr --user
或者
sudo pip3 install tesserocr
我已经使用以下方法安装了 Tesseract 3.04 和 Leptonica 1.73：
sudo apt-get install tesseract-ocr libtesseract-dev libleptonica-dev
出于某种原因，当我尝试安装“tesserocr”时，Cython 会生成编译器错误
daksh@daksh-linux:~/tesser/tesseract$ sudo pip3 install tesserocr
