  bash Miniconda3-py37_4.10.3-Linux-$(arch).sh -b
  cd -
  . ~/miniconda3/etc/profile.d/conda.sh

  After the installation is complete, you can set up Tsinghua source acceleration download for Conda, and see here.

  Create a virtual environment, taking Python 3.7.5 as an example:

  conda create -n mindspore_py37 python=3.7.5 -y
  conda activate mindspore_py37

• Or install Python via APT with the following command.

  sudo apt-get update

  sudo add-apt-repository ppa:deadsnakes/ppa -y
  sudo apt-get install python3.7 python3.7-dev python3.7-distutils python3-pip -y
  # set new installed Python as default
  sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.7 100
  # install pip
  python -m pip install pip -i https://repo.huaweicloud.com/repository/pypi/simple
  sudo update-alternatives --install /usr/bin/pip pip ~/.local/bin/pip3.7 100
  pip config set global.index-url https://repo.huaweicloud.com/repository/pypi/simple

  To install other Python versions, just change 3.7 in the command.

Run the following command to check the Python version.

python --version

Installing GCC and gmp

Run the following commands to install GCC and gmp.

sudo apt-get install gcc-7 libgmp-dev -y

To install a later version of GCC, run the following command to install GCC 8.

sudo apt-get install gcc-8 -y

Or install GCC 9.

sudo apt-get install software-properties-common -y
sudo add-apt-repository ppa:ubuntu-toolchain-r/test

pip install mindspore-dev -i https://pypi.tuna.tsinghua.edu.cn/simple

Of which,

• When the network is connected, dependencies are automatically downloaded during .whl package installation. (For details about the dependencies, see required_package in setup.py .) In other cases, you need to install it by yourself. When running models, you need to install additional dependencies based on requirements.txt specified for different models in ModelZoo. For details about common dependencies, see requirements.txt.
• pip will be installing the latest version of MindSpore Nightly automatically. If you wish to specify the version to be installed, please refer to the instruction below regarding to version update, and specify version manually.

Installation Verification

python -c "import mindspore;mindspore.run_check()"
