## Environment Requirements

### Hardware Requirements

- Ascend 910 AI processor

  > - Reserve at least 32 GB memory for each card.

### System Requirements and Software Dependencies

| Version | Operating System | Executable File Installation Dependencies | Source Code Compilation and Installation Dependencies |
| ---- | :--- | :--- | :--- |
| MindSpore master | - Ubuntu 16.04 or later x86_64 <br> - EulerOS 2.8 arrch64 <br> - EulerOS 2.5 x86_64 | - [Python](https://www.python.org/downloads/) 3.7.5 <br> - Ascend 910 AI processor software package(Version:Atlas T 1.1.T107) <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> - Ascend 910 AI processor software package(Version:Atlas T 1.1.T107) <br> - [wheel](https://pypi.org/project/wheel/) >= 0.32.0 <br> - [GCC](https://gcc.gnu.org/releases.html) 7.3.0 <br> - [CMake](https://cmake.org/download/) >= 3.14.1 <br> - [patch](http://ftp.gnu.org/gnu/patch/) >= 2.5 <br> - [Autoconf](https://www.gnu.org/software/autoconf) >= 2.64 <br> - [Libtool](https://www.gnu.org/software/libtool) >= 2.4.6 <br> - [Automake](https://www.gnu.org/software/automake) >= 1.15.1 <br> **Installation dependencies:**<br> same as the executable file installation dependencies. |

- Confirm that the current user has the right to access the installation path `/usr/local/Ascend `of Ascend 910 AI processor software package(Version:Atlas T 1.1.T107). If not, the root user needs to add the current user to the user group where `/usr/local/Ascend` is located. For the specific configuration, please refer to the software package instruction document.
- When Ubuntu version is 18.04, GCC 7.3.0 can be installed by using apt command.
- 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)
   - [ARM Anaconda](https://github.com/Archiconda/build-tools/releases/download/0.2.3/Archiconda3-0.2.3-Linux-aarch64.sh)

2. 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.

### Configuring software package Dependencies

 - Install the .whl package provided in Ascend 910 AI processor software package(Version:Atlas T 1.1.T107). The .whl package is released with the software package. After software package is upgraded, reinstall the .whl package.

    ```bash
    pip install /usr/local/Ascend/fwkacllib/lib64/topi-{version}-py3-none-any.whl
    pip install /usr/local/Ascend/fwkacllib/lib64/te-{version}-py3-none-any.whl
    pip install /usr/local/Ascend/fwkacllib/lib64/hccl-{version}-py3-none-any.whl
    ```

## Installation Guide

### Installing Using Executable Files

- Download the .whl package from the [MindSpore website](https://www.mindspore.cn/versions/en). It is recommended to perform SHA-256 integrity verification first and run the following command to install MindSpore:

    ```bash
    pip install mindspore-{version}-cp37-cp37m-linux_{arch}.whl
    ```

### Installing Using the Source Code

The compilation and installation must be performed on the Ascend 910 AI processor environment.

1. Download the source code from the code repository.

    ```bash
    git clone https://gitee.com/mindspore/mindspore.git
    ```

2. Run the following command in the root directory of the source code to compile MindSpore:

    ```bash
    bash build.sh -e d -z
    ```
    > - Before running the preceding command, ensure that the paths where the executable files cmake and patch store 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.
    > - In the build.sh script, the default number of compilation threads is 8. If the compiler performance is poor, compilation errors may occur. You can add -j{Number of threads} in to script to reduce the number of threads. For example, `bash build.sh -e d -z -j4`.

3. Run the following command to install MindSpore:

    ```bash
    chmod +x build/package/mindspore-{version}-cp37-cp37m-linux_{arch}.whl
    pip install build/package/mindspore-{version}-cp37-cp37m-linux_{arch}.whl
    ```

## Configuring Environment Variables

- After MindSpore is installed, export runtime-related environment variables.

    ```bash
    # control log level. 0-DEBUG, 1-INFO, 2-WARNING, 3-ERROR, default level is WARNING.
    export GLOG_v=2
    # the root directory of run package
    LOCAL_ASCEND=/usr/local/Ascend
    # Python library that TBE implementation depends on
    export TBE_IMPL_PATH=${LOCAL_ASCEND}/opp/op_impl/built-in/ai_core/tbe
    export PYTHONPATH=${TBE_IMPL_PATH}:${PYTHONPATH}
    # lib libraries that the run package depends on
    export LD_LIBRARY_PATH=${LOCAL_ASCEND}/add-ons/:${LOCAL_ASCEND}/fwkacllib/lib64:${LD_LIBRARY_PATH}
    # TBE operator compilation tool path
    export PATH=${LOCAL_ASCEND}/fwkacllib/ccec_compiler/bin/:${PATH}
    ```

## Installation Verification

- After configuring the environment variables, execute the following Python script：

    ```bash
    import numpy as np
    from mindspore import Tensor
    from mindspore.ops import functional as F
    import mindspore.context as context

    context.set_context(device_target="Ascend")
    x = Tensor(np.ones([1,3,3,4]).astype(np.float32))
    y = Tensor(np.ones([1,3,3,4]).astype(np.float32))
    print(F.tensor_add(x, y))
    ```

- The outputs should be same as:

    ```
    [[[ 2.  2.  2.  2.],
      [ 2.  2.  2.  2.],
      [ 2.  2.  2.  2.]],

     [[ 2.  2.  2.  2.],
      [ 2.  2.  2.  2.],
      [ 2.  2.  2.  2.]],

     [[ 2.  2.  2.  2.],
      [ 2.  2.  2.  2.],
      [ 2.  2.  2.  2.]]]
    ```
