📥 MindSpore Installation Guide

Installation Flow:

• [x] Installing GCC
• [x] Installing Python
• [x] Installing JupyterLab/JupyterNotebook
• [x] Installing MindSpore
• [x] Verify Installation

1st part installation follows https://bbs.huaweicloud.com/forum/thread-108694-1-1.html
2nd part of the installation follows https://mindspore.cn/install
* version of this documentation is Ubuntu Desktop 18.04

Installing prerequisite

sudo apt-get update &&
sudo apt-get install -y build-essential m4 libgmp-dev libmpfr-dev libmpc-dev zlib1g-dev libffi-dev make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev xz-utils tk-dev libffi-dev liblzma-dev python-openssl openssl

Installing GCC (GNU Compiler Collection)

GCC version check (Required 7.3.0 Ver)

gcc --version

* using sudo apt install gcc works, but the version is 7.5.0 we need version 7.3.0 version of gcc.

# Grab the package from internet
wget "http://ftp.gnu.org/gnu/gcc/gcc-7.3.0/gcc-7.3.0.tar.gz"
# Extract the tarball
tar -xzf gcc-7.3.0.tar.gz 
# Go into the extracted folder
cd gcc-7.3.0
# Configuring the gcc installation
 ./configure --enable-checking=release --enable-languages=c,c++ --disable-multilib

make -j 12 && sudo make install -j 12

Make, -j to run multiple make target at once because this process takes time!

After make the GCC should be installed properly. Now we want to replace the GCC on the current machine with a new one(7.3.0) by using a soft link.

sudo ln -sf /usr/local/gcc/bin/gcc /usr/bin/gcc

To confirm the installation is complete

gcc --version

The output should be

gcc (GCC) 7.3.0
Copyright ....

Installing Python (Version 3.7.5)

Visit Python official website https://www.python.org/downloads/release/python-375/ Scroll down to download the Gzipped source tarball version. Or

wget "https://www.python.org/ftp/python/3.7.5/Python-3.7.5.tgz"
# Unzip 
tar -xzf Python-3.7.5.tgz
cd Python-3.7.5
`

From the README.rst we can see that there is command for installation

./configure --with-ssl && 
make &&
sudo make install

if you failed at zlib not available problem please run sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev xz-utils tk-dev libffi-dev liblzma-dev python-openssl openssl

if pip3 failed at installing things due to SSL problems please run ./configure --with-ssl && make && sudo make install

Test your installation

python3 --version

Output should looks like

Python 3.7.5

Install Jupyter Lab

pip3 install jupyterlab

if pip failed due to SSL problem please check References 1

if pip failed due to permissions
use --user flag

Futher problem on installation need to check if jupyter is added into $PATH or run the command as sudo. (ie. sudo pip3 install jupyterlab)

Test the installation with

cd ~
jupyter lab

Installing MindSpore

You can obtain the command of installing MindSpore from https://mindspore.cn/install

Just be aware of the pip command. For python3 uses pip3 for installation instead of pip.

As an example a Ubuntu x86 chipset:

pip3 install https://ms-release.obs.cn-north-4.myhuaweicloud.com/1.2.0/MindSpore/cpu/ubuntu_x86/mindspore-1.2.1-cp37-cp37m-linux_x86_64.whl --trusted-host ms-release.obs.cn-north-4.myhuaweicloud.com

* if its related to permission errors, use add --user flag to install into current user dir

Verifiy Installation

You can verify installation by running the command of python3 -c "import mindspore;print(mindspore.__version__)" The result should be 1.2.1

* if you face error of libcce.so consider reinstalling with pip3 without using the sudo command for MindSpore
