What Do I Do If Model Conversion Takes Too Long When the Development Environment Architecture Is Arm (AArch64)?

Model conversion takes a long time when the OS and architecture configuration of the development environment is Arm (AArch64).

Use the numactl tool to specify the CPU cores for model conversion as follows:

Log in to the development environment as the ATC installation user and run the su root command to switch to the root user.
Ensure that the development environment has Internet access, and run the following command to install the numactl tool:
```
yum -y install numactl
```
Switch to the ATC installation user and run the numactl -C command to specify CPU cores 16–31 to process model conversion:
CPU cores 16–31 are recommended for better processing performance. You can also change the CPU cores as required.
```
numactl -C 16-31 --localalloc <args>
```
Replace <args> with the actual ATC model conversion command.
