Atlas Data Center
CANN Software Installation Guide (Inference)	1 Installation Precautions

1Installation Precautions

Development Environment

The development environment is used to convert model fi		develop and compile
applications, and develop operators.
If you need to debug an application (for example, an image c		fic	n
application) in the development environment in addition to developing and
compiling the application, you need to c nfi	Ascend AI devices (such as
inference cards) in the development environment.

The pure development environment requires only the development kit to be installed.

In the development + commissioning scenario, you also need to install the driver and fi mw corresponding to the inference card.

Operating Environment

The operating environment is an environment for running applications developed


by users. The operating environment must be c nfi		with Ascend AI devices
(such as inference cards). Applications depend on the		ffl n inference engine
package, Toolbox, driver, and fi mw	to perform ffl n accelerated inference.

The operating environment includes the following two scenarios:

● Physical machine scenario: The inference card driver, fi mw ffl n inference engine package, and Toolbox are installed on a physical machine. Applications developed by users run on the physical machine.

●In the container scenario, you need to install Docker.

a.	The inference card driver, fi mw	and Toolbox are installed on a host.
b.	The ffl n inference engine package, user-developed applications, and
	basic container images are encapsulated into a service inference image.

c.In the operating environment, the image is used to start the containers. The applications then run as containers.

package	the content below the
	table.

●For installation as the root user:

After installation as the root user, you must switch to a non-root user for execution (the running user must not belong to the root user group). Therefore, you need to create a running user before the installation.

–If the created user is HwHiAiUser, you can directly install the software packages as the HwHiAiUser user. The default installation user is

HwHiAiUser.

–If the created user is not HwHiAiUser, you need to specify the running user (by using the --install-username=user name --install- usergroup=user group parameter) when installing the software package. Perform the following operations to create a user.

●For installation as a non-root user:

In this scenario, the installation and running users must be the same.

–If a non-root user exists, you do not need to create one.

–If you want to use a new non-root user, you need to create the user fi

To create a non-root user, run the following commands as the root user:

1.Create a non-root user.

groupadd usergroup

useradd -g usergroup -d /home/username -m username

2.Set the password of the non-root user.

passwd username

Issue 01 (2021-03-02)

Atlas Data Center
CANN Software Installation Guide (Inference)	3 Installing the Development Environment

NOTE

● If the CANN software package is installed by a non-root user, the owner group of the user must be the same as that of the driver running user. If they are ff n add them to the Driver running user group.

●The created running user cannot belong to the root user group.

●After the HwHiAiUser user is created, do not disable the login authentication function of the user.

●The password validity period is 90 days. You can change the validity period in the /etc/

(Optional) n g ng the Permission of the Installation User

Skip the following part if you install as the root user.

Before installing the development kit, you need to download the dependencies, which require sudo yum permission. Run the following commands as the root user:

1.Open the /etc/sudoers fi

chmod u+w /etc/sudoers vi /etc/sudoers

2. Under root ALL=(ALL) ALL in the fi add the following content:

username ALL=(ALL:ALL) NOPASSWD:SETENV:/usr/bin/yum, /usr/bin/pip, /bin/tar, /bin/mkdir, /bin/ rm, /bin/sh, /bin/cp, /bin/bash, /usr/bin/make install, /bin/ln -s /usr/local/python3.7.5/bin/

python3 /usr/bin/python3.7, /bin/ln -s /usr/local/python3.7.5/bin/pip3 /usr/bin/pip3.7, /bin/ln -s /usr/ local/python3.7.5/bin/python3 /usr/bin/python3.7.5, /bin/ln -s /usr/local/python3.7.5/bin/pip3 /usr/bin/ pip3.7.5

Replace username with the name of the common user who executes the installation script.

NOTE

Ensure that the last line of the /etc/sudoers fi is #includedir /etc/sudoers.d.

Otherwise, add it manually.

3.Run :wq! to save the fi

4.Run the following command to revoke the write permission on the /etc/

sudoers fi

chmod u-w /etc/sudoers

Setting the Source

Development kit installation requires the download of related dependencies. Ensure that the installation environment can be connected to the network. Run the following command as the root user to check whether the source is valid:

yum makecache

If an error is reported during command execution or dependency installation, check whether the network connection is normal, or replace the source in

the /etc/yum.repos.d/CentOS-Base.repo fi	with an available source or use an
image source. For details about how to c nfi	a network proxy, see 5.2
n g ng a System Network Proxy.

CANN Software Installation Guide (Inference)	3 Installing the Development Environment

Installing Dependencies

NOTE

●If you install Python and its dependencies as the root user, perform Step 1 to Step 3. Note that the sudo keywords in the commands need to be deleted if any.

●If you install Python and its dependencies as a non-root user, run the su - username command to switch to the non-root user and perform Step 1 to Step 3.

Step 1 Check whether the Python dependencies and GCC software are installed.

Run the following commands to check whether the dependencies such as GCC, Make, and Python are installed:

gcc --version gcc-c++ --version make --version cmake --version

rpm -qa|grep gcc-c++ rpm -qa |grep unzip rpm -qa |grep zlib-devel rpm -qa |grep bffi v

rpm -qa |grep net-tools

If information similar to the following is displayed (the version number varies according to the actual OS), the tool has been installed. Go to the next step.

gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-39) gcc-c++-4.8.5

GNU Make 4.1 cmake version 3.5.1

unzip-6.0-21.el7.aarch64 zlib-devel-1.2.7-18.el7.aarch64 bffi v 3.0.13-18.el7.aarch64

openssl-devel-1.0.2k-19.el7.aarch64 sqlite-devel-3.7.17-8.el7_7.1.aarch64 blas-devel-3.4.2-8.el7.aarch64 lapack-devel-3.4.2-8.el7.aarch64 openblas-devel-0.3.3-2.el7.aarch64 pciutils-3.5.1-3.el7.aarch64 net-tools-2.0-0.24.20131004git.el7.aarch64

Otherwise, run the following command to install the software. You can change the following command to install only some of them as required.

sudo yum install -y gcc gcc-c++ make cmake unzip zlib-devel bffi v openssl-devel sqlite-devel blasdevel lapack-devel openblas-devel pciutils net-tools

In the preceding steps, if the error message "No package libopenblas available" is displayed during the installation of openblas-devel, you need to install the extension package of the Linux enterprise edition and then install openblas-devel again. Run the following command to install the extension package:

sudo yum install epel-release

If the CMake version installed using the preceding method is earlier than 3.5.1, see

5.3 Installing CMake 3.5.2.

Step 2 Check whether the Python development environment is installed.

The development kit depends on the Python environment. Run the python3.7.5 -- version and pip3.7.5 --version commands to check whether Python has been

Issue 01 (2021-03-02)

CANN Software Installation Guide (Inference)	3 Installing the Development Environment

installed. If the following information is displayed, Python has been installed. Go to the next step.

Python 3.7.5

pip 19.2.3 from /usr/local/python3.7.5/lib/python3.7/site-packages/pip (python 3.7)

Otherwise, use the following procedure to install Python 3.7.5:

1.Run the wget command to download the source code package of Python 3.7.5 to any directory of the installation environment. The command is as

follows:

wget https://www.python.org/ftp/python/3.7.5/Python-3.7.5.tgz

2.Run the following command to go to the download directory and decompress

the source code package:

tar -zxvf Python-3.7.5.tgz

3. Go to the decompressed folder and run the following c nfi							n build, and
installation commands:
	cd Python-3.7.5
	c nfi	fix	c y	n3 7 5 --enable-shared
	make
	sudo make install
	The	x parameter		c fi	the Python installation path. You can change
	it based on the site requirements. The --enable-shared parameter is used to
	compile the libpython3.7m.so.1.0 dynamic library.
	This document uses			x	y n3	as an example. After the
	c nfi	n	compilation, and installation commands are executed, the

installation package is output to the /usr/local/python3.7.5 directory, and the libpython3.7m.so.1.0 dynamic library is output to the /usr/local/ python3.7.5/lib/libpython3.7m.so.1.0 directory.

4.Check whether libpython3.7m.so.1.0 exists in /usr/lib64 or /usr/lib. If yes,

skip this step or back up the libpython3.7m.so.1.0 fi provided by the system and run the following command:

Copy the compiled fi libpython3.7m.so.1.0 to /usr/lib64:

sudo cp /usr/local/python3.7.5/lib/libpython3.7m.so.1.0 /usr/lib64

When the following information is displayed, enter y to overwrite the libpython3.7m.so.1.0 fi provided by the system.

cp: overwrite 'libpython3.7m.so.1.0'?y

If the /usr/lib64 directory does not exist in the environment, copy the fi to the /usr/lib directory.

sudo cp /usr/local/python3.7.5/lib/libpython3.7m.so.1.0 /usr/lib

Replace the path of the libpython3.7m.so.1.0 fi as required.

5.Run the following commands to set the soft link:

sudo ln -s /usr/local/python3.7.5/bin/python3 /usr/bin/python3.7 sudo ln -s /usr/local/python3.7.5/bin/pip3 /usr/bin/pip3.7

sudo ln -s /usr/local/python3.7.5/bin/python3 /usr/bin/python3.7.5 sudo ln -s /usr/local/python3.7.5/bin/pip3 /usr/bin/pip3.7.5

If a message indicating that the link already exists is displayed during the command execution, run the following command to delete the existing link and run the command again:

sudo rm -rf /usr/bin/python3.7.5 sudo rm -rf /usr/bin/pip3.7.5 sudo rm -rf /usr/bin/python3.7 sudo rm -rf /usr/bin/pip3.7
