See README file for more information.刚刚你修改后报这个错误

这个错误提示是说找不到安装的 OCR 引擎 Tesseract 或者 Tesseract 没有在你的环境变量 PATH 中。为了解决这个问题，你需要安装 Tesseract 并将其添加到 PATH 中。你可以从以下链接下载 Tesseract：https://github.com/UB-Mannheim/tesseract/wiki。安装完成后，将 Tesseract 的安装路径添加到 PATH 中即可。

根据您提供的信息，看起来是您在使用requests库时出现了错误。根据错误信息，代码中的headers应该是一个set对象，而不是一个dict对象，所以出现了'AttributeError: 'set' object has no attribute 'items''的错误。

您可以尝试将headers改为一个dict对象，例如：

import requests

url = 'http://example.com/api'
headers = {'User-Agent': 'Mozilla/5.0'}

response = requests.get(url, headers=headers)

print(response.text)

在这个例子中，我们使用了一个包含User-Agent头的headers字典。请确保headers是一个dict对象，并且您的请求URL有效。

如果出现 `ImportError: cannot import name 'Concatenate' from 'typing'` 错误，可能是因为 PyCUDA 依赖的 `typing` 模块版本过低所致。可以尝试更新 `typing` 模块或者升级 Python 到最新版本。另外，也可以尝试升级 PyCUDA 到最新版本，最新版本的 PyCUDA 已经支持 Python 3.9。
