Installing the MindIO TFT SDK on Compute Nodes

Procedure

1. Log in to the installation node as the {MindIO-install-user} user.
   

   The password set by the installation user must meet the password complexity requirements. For details, see Password Complexity Requirements. The password validity period is 90 days. You can change the validity period in the /etc/login.defs file or run the chage command to set the validity period. For details, see Setting the Validity Period of a User Account.

2. Upload the memory cache system software package to a path on the device on which the installation user has the read and write permissions.
   

   • Use the actual memory cache system software package.
   • If the Python environment is a shared directory, upload the installation package to any compute node. Otherwise, upload the installation package to all compute nodes.
3. Go to the software package upload path and decompress the memory cache system software package.

   unzip Ascend-mindxdl-mindio_{version}_linux-{arch}.zip
