Installing the Development Environment

The development environment refers to an environment used by a user to develop an application program. It is usually deployed a PC or a server.

The development kit must be installed in the development environment. In the scenario where the operating environment is deployed on an ARM device and the development environment is deployed on an x86-architecture device, you need to install the development kits of both the x86 and ARM architectures and the cross compilation tool in the development environment.

Installing the Operating Environment

The operating environment is the environment for running applications developed by users. The operating environment requires the devices. See Atlas 500 AI edge station.

congure a network proxy, see 4.1 Conguring a System

Network Proxy.

Installing Dependencies

● If you install Python and its dependencies as the root user, perform 1 to 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:

lib-dev| grep lib-dev| grep ii

If the following information is displayed, the installation is complete. Go to the next step.

gcc (Ubuntu 7.3.0-3ubuntu1~18.04) 7.3.0 g++ (Ubuntu 7.3.0-3ubuntu1~18.04) 7.3.0 GNU Make 4.1 cmake version 3.10.2 zlib1g:amd64 1:1.2.11.dfsg-0ubuntu2 amd64 compression library - runtime zlib1g-dev:amd64 1:1.2.11.dfsg-0ubuntu2 amd64 compression library - development libsqlite3-dev:amd64 3.22.0-1ubuntu0.3 amd64 SQLite 3 development openssl 1.1.1-1ubuntu2.1~18.04.5 amd64 Secure Sockets Layer toolkit - cryptographic utility libssl-dev:amd64 1.1.1-1ubuntu2.1~18.04.5 amd64 Secure Sockets Layer toolkit - development lib-dev:amd64 3.2.1-8 amd64 Foreign Function Interface library (development les) unzip 6.0-21ubuntu1 amd64 De-archiver for .zip les pciutils 1:3.5.2-1ubuntu1.1 amd64 Linux PCI Utilities net-tools 1.60+git20161116.90da8a0-1ubuntu1 amd64 NET-3 networking toolkit

les

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

CA UTION

Atlas Intelligent Edge CANN Software Installation Guide (A500-3000, A500-3010) 2 Installing the Development Environment

● If you install dependencies as the root user, delete sudo from the commands in steps 1 and 2.

● If Python and its dependency are installed as a non-root user, run the su -

username

command to switch to the non-root user, and then perform step 1

to step 3.

● libsqlite3-dev must be installed before the Python installation. If the Python

3.7.5 environment has been installed in the user's OS and libsqlite3-dev is installed after the Python 3.7.5 environment is installed, you need to rebuild the Python environment.

sudo apt-get install -y gcc g++ make cmake zlib1g zlib1g-dev libsqlite3-dev openssl libssl-dev lib-dev unzip pciutils net-tools

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 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 conguration, build, and

installation commands:

cd Python-3.7.5 ./congure --prex=/usr/local/python3.7.5 --enable-loadable-sqlite-extensions --enable-shared make sudo make install

--prex parameter species the Python installation path. You can change

The it based on the site requirements. The --enable-shared parameter is used to compile the libpython3.7m.so.1.0 dynamic library. The --enable-loadable- sqlite-extensions parameter is used to load libsqlite3-dev.

This document uses

--prex=/usr/local/python3.7.5 as an example. After the conguration, 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

le provided by the system

and run the following command:

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

sudo cp /usr/local/

python3.7.5/lib/

libpython3.7m.so.1.0 /usr/lib64

Atlas Intelligent Edge CANN Software Installation Guide (A500-3000, A500-3010) 2 Installing the Development Environment

When the following information is displayed, enter y to overwrite the libpython3.7m.so.1.0 le 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 le 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 le 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 commands to delete the existing link and run the commands 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

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

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

7. Set the Python 3.7.5 environment variables.

a. Run the vi ~/.bashrc command in any directory as the running user to

open the .bashrc

# Set the Python 3.7.5 library path. export LD_LIBRARY_PATH=/usr/local/python3.7.5/lib:$LD_LIBRARY_PATH # If multiple Python 3 versions exist in the user environment, specify Python 3.7.5. export PATH=/usr/local/python3.7.5/bin:$PATH

b. Run the :wq! command to save the

le and append the following content to the le:

le and exit.

c. Run the source ~/.bashrc command for the modication to take eect

immediately.

8. After the installation is complete, run the following commands to check the installation version. If the required version information is displayed, the installation is successful.

python3.7.5 --version pip3.7.5 --version

Step 3 Install the Python 3 development environment.

Before the installation, run the pip3.7.5 list command to check whether the dependencies have been installed. If yes, skip this step. If not, run the following command to install the dependencies: (If only some of the software is not installed, modify the following command to install selected software only.)

If you install Python and its dependencies as a non-root user, add --user at the end of each command in this step to ensure that the installation is successful. Example command: pip3.7.5 install attrs --user

pip3.7.5 install attrs pip3.7.5 install psutil pip3.7.5 install decorator pip3.7.5 install numpy pip3.7.5 install protobuf== pip3.7.5 install scipy pip3.7.5 install sympy pip3.7.5 install
