To install the CANN toolkit on Ascend NPU hardware, you can use either offline installation packages or online installation alternatives. The process includes verifying prerequisites, executing the installation, and setting up environment variables to enable development workflows.

Before setting up the CANN environment, you must verify that the Ascend device is correctly recognized and confirm that base dependencies like drivers, Python, and pip are ready. This environment check ensures a reliable foundation for the CANN installation.

Yes, you can install CANN offline on an Ascend NPU without a network connection. The installation guide provides specific offline installation package steps tailored for environments lacking internet access, alongside online alternatives for controlled networks.

To validate your CANN installation and NPU environment setup, you execute specific verification commands provided after configuring the runtime dependencies and environment variables. These basic functionality checks confirm the CANN environment operates reliably.

If your Ascend NPU is not recognized during CANN setup, the base driver dependencies may not be ready. You must execute an environment check to confirm driver readiness and ensure the Ascend device is properly detected before starting installation.

The best way to configure CANN environment variables after installing the toolkit is to follow the setup steps specified for the Ascend NPU platform. Proper environment configuration ensures runtime dependencies are resolved and development workflows function correctly.
