Item

Description

OS

Windows OS. Windows 7 or later is recommended.

Installing Python

Python 2.7 or later is recommended.

Installing Python library dependency

OCR Python SDK depends on the third-party requests 2.18.2 library package.

Procedure

The following describes how to install and configure Python 2.7 in the Windows 7 environment. If you have installed Python 2.7 or later and requests 2.18.2, skip this section.

  1. Download your desired Python installation package from https://www.python.org/downloads/release/python-2711/
  2. After the Python installation package is downloaded, install it as prompted. The default path is C:\Python27.
  3. Right-click Computer, choose Properties > Advanced System Settings > Environment Variables. Add C:\Python27;C:\Python27\Scripts to Path.
  4. Open the command line interface (CLI) and run python –v. If the information shown in Figure 1 is displayed, the configuration is successful.

  5. Run the following command in the new CMD window of PIP to install the requests package: 
    1
    		 
    pip install -i https://pypi.tuna.tsinghua.edu.cn/simple requests --trusted-host https://pypi.tuna.tsinghua.edu.cn/simple
  6. After the installation is complete, run the PIP command to check whether the requests package is correctly installed. See Figure 2.
