在 Sagemaker Jupyter notebook 中运行 pytesseract

Question

我想在我的 Sagemaker Jupyter 笔记本中使用 pytesseract。

我正在关注 tutorial 安装 pytesseract。运行 pip install 后：

!pip install pytesseract
Looking in indexes: https://pypi.org/simple, https://pip.repos.neuron.amazonaws.com
Requirement already satisfied: pytesseract in /home/ec2-user/anaconda3/envs/pytorch_p38/lib/python3.8/site-packages (0.3.10)
Requirement already satisfied: Pillow>=8.0.0 in /home/ec2-user/anaconda3/envs/pytorch_p38/lib/python3.8/site-packages (from pytesseract) (9.0.1)
Requirement already satisfied: packaging>=21.3 in /home/ec2-user/anaconda3/envs/pytorch_p38/lib/python3.8/site-packages (from pytesseract) (21.3)
Requirement already satisfied: pyparsing!=3.0.5,>=2.0.2 in /home/ec2-user/anaconda3/envs/pytorch_p38/lib/python3.8/site-packages (from packaging>=21.3->pytesseract) (3.0.6)

该教程指示我应该将 tesseract 可执行文件添加到我的路径但是我不知道 pip 在哪里安装这个可执行文件？

# If you don't have tesseract executable in your PATH, include the following:
pytesseract.pytesseract.tesseract_cmd = r'<full_path_to_your_tesseract_executable>'

如果我尝试在没有这个的情况下运行 pytesseract，我会收到一条错误消息：

from PIL import Image

import pytesseract

print(pytesseract.image_to_string(Image.open(testimage)))

结果是：

~/anaconda3/envs/pytorch_p38/lib/python3.8/site-packages/pytesseract/pytesseract.py in run_tesseract(input_filename, output_filename_base, extension, lang, config, nice, timeout)
    258             raise
    259         else:
--> 260             raise TesseractNotFoundError()
    261 
    262     with timeout_manager(proc, timeout) as error_string:

TesseractNotFoundError: tesseract is not installed or it's not in your PATH. See README file for more information.

我能够在这里找到 pytesseract 安装：

/home/ec2-user/anaconda3/envs/JupyterSystemEnv/lib/python3.7/site-packages/pytesseract

但是，当我使用该位置更新 tesseract_cmd 并调用相同的代码时，我得到：

PermissionError: [Errno 13] Permission denied: '/home/ec2-user/anaconda3/envs/JupyterSystemEnv/lib/python3.7/site-packages/pytesseract'

我的问题与此 question 不同（但相关），当我链接到 tesseract 二进制文件时，我收到权限被拒绝的错误。
