This document describes how to quickly install MindSpore by pip in a Windows system with a CPU environment.

For details about how to install third-party dependency software when confirming the system environment information, see the third-party dependency software installation section in the Installing MindSpore Using Source Code Build on Windows (CPU) provided by the community. Thanks to the community member lvmingfu for sharing.

System Environment Information Confirmation

• Ensure that Windows 10 is installed with the x86 architecture 64-bit operating system.
• Ensure that you have Python versions between 3.7 to 3.9 installed. If not installed, follow the links to Python official website or Huawei Cloud to download and install Python.
• After installing Python, add Python and pip to the environment variable.
  • Add Python: Control Panel -> System -> Advanced System Settings -> Environment Variables. Double click the Path in the environment variable and add the path of python.exe.
  • Add pip: The Scripts folder in the same directory python.exe is the pip file that comes with Python, and add it to the system environment variable.

Installing MindSpore

First, refer to Version List to select the version of MindSpore you want to install, and perform SHA-256 integrity check. Taking version 1.8.1 as an example, execute the following commands.

set MS_VERSION=1.8.1

Then run the following commands to install MindSpore according to Python version.

# Python3.7
pip install https://ms-release.obs.cn-north-4.myhuaweicloud.com/%MS_VERSION%/MindSpore/cpu/x86_64/mindspore-%MS_VERSION:-=%-cp37-cp37m-win_amd64.whl --trusted-host ms-release.obs.cn-north-4.myhuaweicloud.com -i https://pypi.tuna.tsinghua.edu.cn/simple
# Python3.8
pip install https://ms-release.obs.cn-north-4.myhuaweicloud.com/%MS_VERSION%/MindSpore/cpu/x86_64/mindspore-%MS_VERSION:-=%-cp38-cp38-win_amd64.whl --trusted-host ms-release.obs.cn-north-4.myhuaweicloud.com -i https://pypi.tuna.tsinghua.edu.cn/simple
# Python3.9
pip install https://ms-release.obs.cn-north-4.myhuaweicloud.com/%MS_VERSION%/MindSpore/cpu/x86_64/mindspore-%MS_VERSION:-=%-cp39-cp39-win_amd64.whl --trusted-host ms-release.obs.cn-north-4.myhuaweicloud.com -i https://pypi.tuna.tsinghua.edu.cn/simple

When the network is connected, dependency items are automatically downloaded during .whl package installation. (For details about the dependency, 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.

Installation Verification

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

The outputs should be the same as:

MindSpore version: __version__
The result of multiplication calculation is correct, MindSpore has been installed successfully!

It means MindSpore has been installed successfully.

Version Update

Use the following command if you need to update the MindSpore version:

pip install --upgrade mindspore=={version}

Of which,

• When updating to a release candidate (rc) version, {version} should be specified manually, e.g. 1.5.0rc1; When updating to a standard release, =={version} could be removed.
