Installing MindX SDK

Prerequisites

  • The preparations for the installation are complete. For details, see System Requirements.
  • The inference card driver and firmware have been installed in the environment.
  • The MindX SDK software package has been obtained. For details, see Obtaining Software Packages.
  • The CANN development kit has been installed. For details, see Installing the CANN Development Kit.
  • Run the following command to make the environment variables take effect:
    # Install Toolkit as the root user:
. /usr/local/Ascend/ascend-toolkit/set_env.sh
# Install Toolkit as a non-root user:
. $HOME/Ascend/ascend-toolkit/set_env.sh

    Use the actual installation path.

    If the operating environment is Atlas 500 AI edge station, configure environment variables as follows.

    # Run the following command to make the environment variables take effect:
. /opt/ascend/nnrt/set_env.sh

Procedure

  • You are advised to install and run the tool as a common user.
  • {version} indicates the version number of the development kit, and {arch} indicates the OS architecture. Replace them as required.
  • The management plane logs related to installation, upgrade, and uninstallation of software packages are saved in the ~/log/mindxsdk/deployment.log file that contains the name of the login user, access address, and host name for subsequent log tracing and auditing.
  • For details about how to uninstall MindX SDK, see Upgrading and Uninstalling MindX SDK.
  1. Log in to the installation environment as the installation user of the software packages.
  2. Upload MindX SDK to any directory in the installation environment and go to the directory where the development kit is stored.
  3. Grant the execute permission on the kit.
    chmod +x Ascend-mindxsdk-mxvision_{version}_linux-{arch}.run
  4. Run the following command to check the consistency and integrity of the kit:
    ./Ascend-mindxsdk-mxvision_{version}_linux-{arch}.run --check

    If the following information is displayed, the kit meets the consistency and integrity requirements:

    Verifying archive integrity...  100%   SHA256 checksums are OK. All good.
  5. Create an installation path for MindX SDK.
    • If you need to specify the installation path, create it first. /home/work/MindX_SDK is an example installation path.
      mkdir -p /home/work/MindX_SDK
    • If you do not specify an installation path, the software is installed in the path where MindX SDK is located by default.
  6. Go to the path to which the MindX SDK software package is uploaded and install MindX SDK. (The installation path cannot contain spaces.)
    • If an installation path is specified, run the following command to install the software. /home/work/MindX_SDK is an example installation path.
      ./Ascend-mindxsdk-mxvision_{version}_linux-{arch}.run --install --install-path=/home/work/MindX_SDK
    • If no installation path is specified, run the following command to install the software in the current path.
      ./Ascend-mindxsdk-mxvision_{version}_linux-{arch}.run --install
    If no error information is displayed after the installation is complete, the software is successfully installed in the specified or default path.
    The installation is successfully

    For details about the API parameters, see Table 1.

    Table 1 API parameters

    Parameter

    Description

    --help | -h

    Queries help information.

    --info

    Queries the construction information.

    --list

    Queries the file list.

    --check

    Queries the integrity of the kit.

    --quiet

    Enables the quiet mode.

    --noexec

    Does not execute internal scripts. Generally, this parameter is used together with the --install and --install-path parameters.

    --install

    Starts the installation.

    --install-path=<path>

    Installs the package in the specified path. Generally, this parameter is used together with --install.

    • You are advised to use an absolute path to install the MindX SDK. Do not use a relative path when specifying the installation path.
    • This parameter conflicts with --version. Do not install the SDK in /tmp.

    --uninstall

    Performs uninstallation. This parameter is valid only for the installation package in the same directory as the RUN package. For details, see Upgrading and Uninstalling MindX SDK.

    --cann-path

    Specifies the user-defined CANN installation path. If the CANN installation path is user-defined, use this parameter to import the path, for example, /home/xxx/Ascend. This parameter is valid only for the root user.

    --upgrade

    Upgrades MindX SDK. For details, see Upgrading and Uninstalling MindX SDK.

    When this operation is performed, the SDK RUN package is temporarily installed in the /tmp directory. If an SDK RUN package already exists in the directory, the original one will be uninstalled. You are not advised to install the SDK in the /tmp directory.

    --version

    Queries the MindX SDK version.

    When this operation is performed, the SDK RUN package is temporarily installed in /tmp. Uninstall it after querying the version number.

    --choose-gcc=<0,1,2>

    Selects the corresponding RUN package based on the GCC version.

    • 0 (default value): Automatically selects the corresponding version.
    • 1: Installs GCC 4.8.5.
    • 2: Installs GCC 7.

    --nox11

    Does not generate virtual terminals. (This parameter is used in MindStudio, and you are not advised to use this parameter.)
  7. Make the environment variables take effect.

    Go to the mxVision installation path and run the following command for the environment variables of MindX SDK to take effect:

    .  set_env.sh
