## Environment Requirements
### System Requirements and Software Dependencies
| Version | Operating System | Executable File Installation Dependencies | Source Code Compilation and Installation Dependencies |
| ---- | :--- | :--- | :--- |
| MindSpore master | Windows 10 x64 | - [Python](https://www.python.org/downloads/) 3.7.5 <br> - For details about other dependency items, see [requirements.txt](https://gitee.com/mindspore/mindspore/blob/master/requirements.txt). | **Compilation dependencies:**<br> - [Python](https://www.python.org/downloads/) 3.7.5 <br> - [MinGW-W64](https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/7.3.0/threads-posix/sjlj/x86_64-7.3.0-release-posix-sjlj-rt_v5-rev0.7z) GCC-7.3.0 <br> - [ActivePerl](http://downloads.activestate.com/ActivePerl/releases/5.24.3.2404/ActivePerl-5.24.3.2404-MSWin32-x64-404865.exe) 5.24.3.2404 <br> - [CMake](https://cmake.org/download/) 3.14.1 <br> - [wheel](https://pypi.org/project/wheel/) >= 0.32.0 <br>**Installation dependencies:**<br> same as the executable file installation dependencies. |
- When the network is connected, dependency items in the requirements.txt file are automatically downloaded during .whl package installation. In other cases, you need to manually install dependency items.
### (Optional) Installing Conda
1. Download the Conda installation package from the following path:
-[X86 Anaconda](https://www.anaconda.com/distribution/) or [X86 Miniconda](https://docs.conda.io/en/latest/miniconda.html)
2. Open Anaconda Prompt from the Windows start menu after installation.
3. Create and activate the Python environment.
```bash
conda create -n {your_env_name} python=3.7.5
conda activate {your_env_name}
```
> Conda is a powerful Python environment management tool. It is recommended that a beginner read related information on the Internet first.
## Installation Guide
### Installing Using Executable Files
1. Download the Windows .whl package of daily version from the [MindSpore repository](https://repo.mindspore.cn/mindspore/). Run the following command to install MindSpore:
2. Run the following command. If no loading error message such as `No module named 'mindspore'` is displayed, the installation is successful.
```bash
python
import mindspore
```
> - Before running the preceding command, ensure that [Visual C ++ Redistributable for Visual Studio 2015](https://www.microsoft.com/zh-CN/download/details.aspx?id=48145) is installed.
### Installing Using the Source Code
1. Download the source code from the code repository.
2. Run the following command in the root directory of the source code to compile MindSpore:
```bash
call build.bat
```
> - Before running the preceding command, ensure that the paths of mingw64\bin\ and the executable files cmake have been added to the environment variable PATH.
> - In the build.sh script, the git clone command will be executed to obtain the code in the third-party dependency database. Ensure that the network settings of Git are correct.
> - If the compiler performance is strong, you can add -j{Number of threads} in to script to increase the number of threads(Default -j6). For example, `call build.bat -j12`.
3. Run the following command to install MindSpore:
4. Run the following command. If no loading error message such as `No module named 'mindspore'` is displayed, the installation is successful.
```bash
python
import mindspore
```
> - Before running the preceding command, ensure that [Visual C ++ Redistributable for Visual Studio 2015](https://www.microsoft.com/zh-CN/download/details.aspx?id=48145) is installed.
