Installing Dependencies

Installing Python Dependency

Install this dependency if you want to use the image input function during operator creation and sample project conversion.

1. Download the Python installation package from the Python official website to a local Windows OS.

   MindStudio supports Python 3.7 to 3.9. The following describes how to install the Python 3.7.5 dependency package.

2. Install Python 3.7.5 to the local environment.
3. In the Windows 10 OS, choose Control Panel > System and Security > System > Advanced system settings. See Figure 1.
   Figure 1 Advance system settings
   
4. In the System Properties dialog box displayed, click Environment Variables. See Figure 2.
   Figure 2 Environment variables
   
5. In the Environment Variables > User variables dialog box, select the Path variable and click Edit. See Figure 3.
   Figure 3 Editing the Path environment variable
   
6. In the Edit environment variable dialog box, click New, enter the paths of the Python 3.7.5 installation package directory and script directory, for example, D:\python and D:\python\Scripts, and click OK. See Figure 4.

7. Click OK.
8. Open the CLI and enter the python -V command to check whether the Python version is 3.7.5.
9. Install the Python 3 dependencies.

   Before the installation, you are advised to run the d:\python\python.exe -m pip3 install --upgrade pip command to perform the upgrade to prevent the installation failure caused by an earlier pip version.

   pip3 install xlrd==1.2.0 
   pip3 install absl-py
   pip3 install numpy
   pip3 install requests

   If the following information is displayed, the installation is successful:

   Successfully installed xlrd-1.2.0
   Successfully installed absl-py-0.12.0 six-1.15.0
   Successfully installed numpy-1.20.1
   Successfully installed request-2.28.0

Installing MinGW Dependency

1. Download the latest MinGW installation package from https://sourceforge.net/projects/mingw-w64/files/. Select a version based on the OS. For example, select x86_64-posix-seh for a 64-bit OS.
2. Decompress the MinGW installation package to a custom directory.
3. In the Windows 10 OS, choose Control Panel > System and Security > System > Advanced system settings. See Figure 5.
   Figure 5 Advance system settings
   
4. In the System Properties dialog box displayed, click Environment Variables. See Figure 6.
   Figure 6 Environment variables
   
5. In the Environment Variables > System variables dialog box, select the Path variable and click Edit. See Figure 7.
   Figure 7 Editing the Path environment variable
   
6. In the Edit environment variable dialog box, click New, enter the path of the bin directory generated after the MinGW installation package is decompressed, for example, D:\mingw64\bin, and click OK. See Figure 8.

7. Open the CLI and enter the gcc -v command.

   If message "gcc version x.x.x (x86_64-win32-seh-rev0, Built by MinGW-W64 project)" is displayed, the installation is successful.
