Installation

Switch to the DDK installation user and perform the following operations:

Run the following command to decompress the installation package:
```
tar -zxvf MSpore_DDK****tar.gz
```
In actual operations, replace MSpore_DDK****.tar.gz.asc with the actual installation package. For details about the decompressed files, see Table 1.
Run the following command to install the DDK:
```
bash install.sh DDK installation directory
```
The DDK installation directory is automatically created during the installation. For example, if the installation directory is set to $HOME/tools/che/ddk, the tools/che/ddk directory is automatically created during the installation. Alternatively, you can specify an installation path.
If the message "Successfully installed the DDK!" is displayed, the DDK has been installed successfully.
- If the message "Warning: DDK functions except TE have been successfully installed." is displayed during the installation, rectify the fault by referring to What Do I Do If the Message "Warning: DDK functions except TE have been successfully installed." Is Displayed During DDK Installation?.
- After the DDK is installed, the profiling function under the installation path $HOME/tools/che/ddk/ddk/toolchains/profiler is unavailable. If you need to use the profiling function, install Mind Studio and the DDK by referring to Ascend 310 Mind Studio Installation Guide (select an installation guide based on the Mind Studio server).
