+- **mmcv**: comprehensive, with full features and various CUDA ops out of the box. It takes longer time to build.
 - **mmcv-lite**: lite, without CUDA ops but all other features, similar to mmcv\<1.0.0. It is useful when you do not need those CUDA ops.
 
 **Note**: Do not install both versions in the same environment, otherwise you may encounter errors like `ModuleNotFound`. You need to uninstall one before installing the other. `Installing the full version is highly recommended if CUDA is available`.
 
-a. Install the full version.
-
-Before installing mmcv, make sure that PyTorch has been successfully installed following the [official guide](https://pytorch.org/). For macOS M1 users, please make sure you are using `PyTorch Nightly`.
-
-We provide pre-built mmcv packages (recommended) with different PyTorch and CUDA versions to simplify the building for **Linux and Windows systems**. In addition, you can run [check_installation.py](.dev_scripts/check_installation.py) to check the installation of mmcv after running the installation commands.
+### Install mmcv
 
-i. Install the latest version.
+Before installing mmcv, make sure that PyTorch has been successfully installed following the [PyTorch official installation guide](https://github.com/pytorch/pytorch#installation). For macOS M1 users, please make sure you are using `PyTorch Nightly`.
 
-The rule for installing the latest `mmcv` is as follows:
+The command to install mmcv on Linux or Windows platforms is as follows (if your system is macOS, please refer to [build mmcv from source](https://mmcv.readthedocs.io/en/2.x/get_started/build.html#macos-mmcv))
 
-```shell
-pip install 'mmcv>=2.0.0rc1' -f https://download.openmmlab.com/mmcv/dist/{cu_version}/{torch_version}/index.html
+```bash
+pip install -U openmim
+mim install 'mmcv>=2.0.0rc1'
 ```
 
-Please replace `{cu_version}` and `{torch_version}` in the url to your desired one. For example,
-to install the latest `mmcv` with `CUDA 11.1` and `PyTorch 1.9.0`, use the following command:
+If you need to specify the version of mmcv, you can use the following command
 
-```shell
-pip install 'mmcv>=2.0.0rc1' -f https://download.openmmlab.com/mmcv/dist/cu111/torch1.9.0/index.html
+```bash
+mim install mmcv==2.0.0rc1
 ```
 
-**Note**: mmcv is only compiled on PyTorch 1.x.0 because the compatibility usually holds between 1.x.0 and 1.x.1. If your PyTorch version is 1.x.1, you can install mmcv compiled with PyTorch 1.x.0 and it usually works well. For example, if your PyTorch version is 1.8.1 and CUDA version is 11.1, you can use the following command to install mmcv.
+If you find that the above installation command does not use a pre-built package ending with `.whl` but a source package ending with `.tar.gz`, you may not have a pre-build package corresponding to the PyTorch or CUDA or mmcv version, in which case you can [build mmcv from source](https://mmcv.readthedocs.io/en/2.x/get_started/build.html).

 **注意**: 请不要在同一个环境中安装两个版本，否则可能会遇到类似 `ModuleNotFound` 的错误。在安装一个版本之前，需要先卸载另一个。`如果 CUDA 可用，强烈推荐安装 mmcv`。
 
-a. 安装完整版
-
-在安装 mmcv 之前，请确保 PyTorch 已经成功安装在环境中，可以参考 PyTorch [官方文档](https://pytorch.org/)。对于使用 macOS M1 的用户，请确保你的 PyTorch 是 `Nightly` 版本。
-
-我们提供了 **Linux 和 Windows 平台** PyTorch 和 CUDA 版本组合的 mmcv 预编译包，可以大大简化用户安装编译过程。强烈推荐通过预编译包来安装。另外，安装完成后可以运行 [check_installation.py](.dev_scripts/check_installation.py) 脚本检查 mmcv 是否安装成功。
+### 安装 mmcv
 
-i. 安装最新版本
+在安装 mmcv 之前，请确保 PyTorch 已经成功安装在环境中，可以参考 [PyTorch 官方安装文档](https://github.com/pytorch/pytorch#installation)。
 
-如下是安装最新版 `mmcv` 的命令
+在 Linux 和 Windows 平台安装 mmcv 的命令如下（如果你的系统是 macOS，请参考[源码安装 mmcv](https://mmcv.readthedocs.io/zh_CN/2.x/get_started/build.html#macos-mmcv)）
 
-```shell
-pip install 'mmcv>=2.0.0rc1' -f https://download.openmmlab.com/mmcv/dist/{cu_version}/{torch_version}/index.html
+```bash
+pip install -U openmim
+mim install 'mmcv>=2.0.0rc1'
 ```
 
-请将链接中的 `{cu_version}` 和 `{torch_version}` 根据自身需求替换成实际的版本号，例如想安装和 `CUDA 11.1`、`PyTorch 1.9.0` 兼容的最新版 `mmcv`，使用如下替换过的命令
+如果需要指定 mmcv 的版本，可以使用以下命令
 
-```shell
-pip install 'mmcv>=2.0.0rc1' -f https://download.openmmlab.com/mmcv/dist/cu111/torch1.9.0/index.html
+```bash
+mim install mmcv==2.0.0rc1
 ```
 
-**注意**: PyTorch 在 1.x.0 和 1.x.1 之间通常是兼容的，故 mmcv 只提供 1.x.0 的编译包。如果你的 PyTorch 版本是 1.x.1，你可以放心地安装在 1.x.0 版本编译的 mmcv。例如，如果你的 PyTorch 版本是 1.8.1、CUDA 版本是 11.1，你可以使用以下命令安装 mmcv。
-
-```shell
-pip install 'mmcv>=2.0.0rc1' -f https://download.openmmlab.com/mmcv/dist/cu111/torch1.8.0/index.html
-```
+如果发现上述的安装命令没有使用预编译包（以 `.whl` 结尾）而是使用源码包（以 `.tar.gz` 结尾）安装，则有可能是我们没有提供和当前环境的 PyTorch 版本、CUDA 版本相匹配的 mmcv 预编译包，此时，你可以[源码安装 mmcv](https://mmcv.readthedocs.io/zh_CN/2.x/get_started/build.html)。
 
-如果想知道更多 CUDA 和 PyTorch 版本的命令，可以参考下面的表格，将链接中的 `=={mmcv_version}` 删去即可。

+mmcv can be built in two ways:
 
-##### Option 2: Build MMCV (full version with CPU)
+1. Full version (CPU ops)
 
-1. Finish above common steps
+   Module `ops` will be compiled as a pytorch extension, but only x86 code will be compiled. The compiled ops can be executed on CPU only.
 
-2. Set up environment variables
+2. Full version (CUDA ops)
 
-   ```shell
-   $env:MMCV_WITH_OPS = 1
-   $env:MAX_JOBS = 8  # based on your available number of CPU cores and amount of memory
-   ```
+   Both x86 and CUDA codes of `ops` module will be compiled. The compiled version can be run on both CPU and CUDA-enabled GPU (if implemented).
 
-3. Following build steps of the lite version
+###### CPU version
 
-   ```shell
-   # activate environment
-   conda activate mmcv
-   # change directory
-   cd mmcv
-   git checkout 2.x
-   # build
-   python setup.py build_ext # if success, cl will be launched to compile ops
-   # install
-   python setup.py develop
-   # check
-   pip list
-   ```
+Build and install
 
-##### Option 3: Build MMCV (full version with CUDA)
+```powershell

-   <... omit some lines ...>
    ```
 
    This should already be done by CUDA installer. If not, or you have multiple version of CUDA toolkit installed, set it with
 
-   ```shell
-   $env:CUDA_HOME = "C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.2"
+   ```powershell
+   (mmcv) PS C:\Users\xxx\mmcv> $env:CUDA_HOME = "C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.2"
    # OR
-   $env:CUDA_HOME = $env:CUDA_PATH_V10_2 # if CUDA_PATH_V10_2 is in envs:
+   (mmcv) PS C:\Users\xxx\mmcv> $env:CUDA_HOME = $env:CUDA_PATH_V10_2 # if CUDA_PATH_V10_2 is in envs:
    ```
 
-3. Set CUDA target arch
+2. Set CUDA target arch
 
    ```shell
-   # Suppose you are using GTX 1080, which is of capability 6.1
-   $env:TORCH_CUDA_ARCH_LIST="6.1"
-   # OR build all supported arch, will be slow
-   $env:TORCH_CUDA_ARCH_LIST="3.5 3.7 5.0 5.2 6.0 6.1 7.0 7.5"
+   # Here you need to change to the target architecture corresponding to your GPU

 Do not install both versions in the same environment, otherwise you may encounter errors like `ModuleNotFound`. You need to uninstall one before installing the other. `Installing the full version is highly recommended if CUDA is avaliable`.
 ```
 
-a. Install the full version.
+### Install mmcv
 
-Before installing mmcv, make sure that PyTorch has been successfully installed following the [official guide](https://pytorch.org/). For macOS M1 users, please make sure you are using `PyTorch Nightly`.
+```{note}
+The following installation steps are for Linux and Windows platforms only. To install mmcv on macOS platform, please refer to [build mmcv from source](build.md#build-on-macos).
+```
 
-We provide pre-built mmcv packages (recommended) with different PyTorch and CUDA versions to simplify the building for **Linux and Windows systems**. In addition, you can run [check_installation.py](https://github.com/open-mmlab/mmcv/blob/2.x/.dev_scripts/check_installation.py) to check the installation of mmcv after running the installation commands.
+Before installing mmcv-full, make sure that PyTorch has been successfully installed following the [PyTorch official installation guide](https://pytorch.org/get-started/locally/#start-locally). This can be verified using the following command
 
-i. Install the latest version.
+```bash
+python -c 'import torch;print(torch.__version__)'
+```
 
-The rule for installing the latest `mmcv` is as follows:
+If version information is output, then PyTorch is installed.
 
-```shell
-pip install 'mmcv>=2.0.0rc1' -f https://download.openmmlab.com/mmcv/dist/{cu_version}/{torch_version}/index.html
-```
+#### Install with mim (recommended)
 
-Please replace `{cu_version}` and `{torch_version}` in the url to your desired one. For example,
-to install the latest `mmcv` with `CUDA 11.1` and `PyTorch 1.9.0`, use the following command:
+[mim](https://github.com/open-mmlab/mim) is the package management tool for the OpenMMLab projects, which makes it easy to install mmcv
 
-```shell
-pip install 'mmcv>=2.0.0rc1' -f https://download.openmmlab.com/mmcv/dist/cu111/torch1.9.0/index.html
+```bash
+pip install -U openmim
+mim install 'mmcv>=2.0.0rc1'
 ```
 
-For more details, please refer the the following tables and delete `=={mmcv_version}`.
+If you find that the above installation command does not use a pre-built package ending with `.whl` but a source package ending with `.tar.gz`, you may not have a pre-build package corresponding to the PyTorch or CUDA or mmcv version, in which case you can [build mmcv from source](build.md).

-First of all, please refer to the Releases and replace `{mmcv_version}` a specified one. e.g. `2.0.0rc1`.
-Then replace `{cu_version}` and `{torch_version}` in the url to your desired versions. For example,
-to install `mmcv==2.0.0rc1` with `CUDA 11.1` and `PyTorch 1.9.0`, use the following command:
+:::{note}
+If you would like to use `opencv-python-headless` instead of `opencv-python`,
+e.g., in a minimum container environment or servers without GUI,

-```shell
-pip install mmcv==2.0.0rc1 -f https://download.openmmlab.com/mmcv/dist/cu111/torch1.9.0/index.html
+Alternatively, if it takes too long to install a dependency library, you can specify the pypi source

-```{note}
-mmcv does not provide pre-built packages for `cu102-torch1.11` and `cu92-torch*` on Windows.
+You can run [check_installation.py](https://github.com/open-mmlab/mmcv/blob/2.x/.dev_scripts/check_installation.py) to check the installation of mmcv after running the installation commands.
+
+#### Using mmcv with Docker
+
+Build with local repository
+
+```bash
+git clone https://github.com/open-mmlab/mmcv.git && cd mmcv
+docker build -t mmcv -f docker/release/Dockerfile .
 ```
 
-Another way is to compile locally by running
+Or build with remote repository
 
-```python
-pip install 'mmcv>=2.0.0rc1'
+```bash
+docker build -t mmcv https://github.com/open-mmlab/mmcv.git#2.x:docker/release
 ```
 
-Note that the local compiling may take up to 10 mins.
+The [Dockerfile](release/Dockerfile) installs latest released version of mmcv-full by default, but you can specify mmcv versions to install expected versions.
 
-b. Install the lite version.
+```bash
+docker image build -t mmcv -f docker/release/Dockerfile --build-arg MMCV=2.0.0rc1 .
+```
+
+If you also want to use other versions of PyTorch and CUDA, you can also pass them when building docker images.
+
+An example to build an image with PyTorch 1.11 and CUDA 11.3.
+
+```bash
+docker build -t mmcv -f docker/release/Dockerfile \
+    --build-arg PYTORCH=1.11.0 \
+    --build-arg CUDA=11.3 \
+    --build-arg CUDNN=8 \
+    --build-arg MMCV=2.0.0rc1 .
+```
+
+More available versions of PyTorch and CUDA can be found at [dockerhub/pytorch](https://hub.docker.com/r/pytorch/pytorch/tags).
+
+### Install mmcv-lite
+
+If you need to use PyTorch-related modules, make sure PyTorch has been successfully installed in your environment by referring to the [PyTorch official installation guide](https://github.com/pytorch/pytorch#installation).
 
 ```python
 pip install mmcv-lite
 ```

 ## 从源码编译 MMCV
 
-### 在 Linux 或者 macOS 上编译 MMCV
+### 编译 mmcv
 
-克隆算法库
+在编译 mmcv 之前，请确保 PyTorch 已经成功安装在环境中，可以参考 [PyTorch 官方安装文档](https://pytorch.org/get-started/locally/#start-locally)。可使用以下命令验证
 
 ```bash
-git clone https://github.com/open-mmlab/mmcv.git
-cd mmcv
-git checkout 2.x
+python -c 'import torch;print(torch.__version__)'
 ```
 
-建议安装 `ninja` 以加快编译速度
+:::{note}
 
-```bash
-pip install -r requirements/optional.txt
-```
-
-你可以安装 lite 版本
+- 如果克隆代码仓库的速度过慢，可以使用以下命令克隆（注意：gitee 的 mmcv 不一定和 github 的保持一致，因为每天只同步一次）
 
 ```bash
-MMCV_WITH_OPS=0 pip install -e .
+git clone https://gitee.com/open-mmlab/mmcv.git
 ```
 
-也可以安装 full 版本
+- 如果打算使用 `opencv-python-headless` 而不是 `opencv-python`，例如在一个很小的容器环境或者没有图形用户界面的服务器中，你可以先安装 `opencv-python-headless`，这样在安装 mmcv 依赖的过程中会跳过 `opencv-python`。
+
+- 如果编译过程安装依赖库的时间过长，可以[设置 pypi 源](https://mirrors.tuna.tsinghua.edu.cn/help/pypi/)
 
 ```bash
-pip install -e .
+pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple
 ```
 
-如果是在 macOS 上编译，则需要在安装命令前添加一些环境变量，同时对于使用 macOS M1 的用户，请确保你的 PyTorch 是  `Nightly` 版本。

-a. 安装完整版
+### 安装 mmcv
 
-在安装 mmcv 之前，请确保 PyTorch 已经成功安装在环境中，可以参考 PyTorch 官方[文档](https://pytorch.org/)。对于使用 macOS M1 的用户，请确保你的 PyTorch 是 `Nightly` 版本。
+```{note}
+下述安装步骤仅适用于 Linux 和 Windows 平台，如需在 macOS 平台安装 mmcv，请参考[源码安装 mmcv](build.md#在-macos-上编译-mmcv)。
+```
+
+在安装 mmcv 之前，请确保 PyTorch 已经成功安装在环境中，可以参考 [PyTorch 官方安装文档](https://pytorch.org/get-started/locally/#start-locally)。可使用以下命令验证
+
+```bash
+python -c 'import torch;print(torch.__version__)'
+```
 
-我们提供了 **Linux 和 Windows 平台** PyTorch 和 CUDA 版本组合的 mmcv 预编译包，可以大大简化用户安装编译过程。强烈推荐通过预编译包来安装。另外，安装完成后可以运行 [check_installation.py](https://github.com/open-mmlab/mmcv/blob/2.x/.dev_scripts/check_installation.py) 脚本检查 mmcv 是否安装成功。
+如果输出版本信息，则表示 PyTorch 已安装。
 
-i. 安装最新版本
+#### 使用 mim 安装（推荐）
 
-如下是安装最新版 `mmcv` 的命令
+[mim](https://github.com/open-mmlab/mim) 是 OpenMMLab 项目的包管理工具，使用它可以很方便地安装 mmcv。
 
-```shell
-pip install 'mmcv>=2.0.0rc1' -f https://download.openmmlab.com/mmcv/dist/{cu_version}/{torch_version}/index.html
+```bash
+pip install -U openmim
+mim install 'mmcv>=2.0.0rc1'
 ```
 
-请将链接中的 `{cu_version}` 和 `{torch_version}` 根据自身需求替换成实际的版本号，例如想安装和 `CUDA 11.1`、`PyTorch 1.9.0` 兼容的最新版 `mmcv`，使用如下替换过的命令
+如果发现上述的安装命令没有使用预编译包（以 `.whl` 结尾）而是使用源码包（以 `.tar.gz` 结尾）安装，则有可能是我们没有提供和当前环境的 PyTorch 版本、CUDA 版本相匹配的 mmcv 预编译包，此时，你可以[源码安装 mmcv](build.md)。

 ```
 
-```{note}
+:::{note}
+如果你打算使用 `opencv-python-headless` 而不是 `opencv-python`，例如在一个很小的容器环境或者没有图形用户界面的服务器中，你可以先安装 `opencv-python-headless`，这样在安装 mmcv 依赖的过程中会跳过 `opencv-python`。
+
+另外，如果安装依赖库的时间过长，可以指定 pypi 源
+
+```bash
+mim install 'mmcv>=2.0.0rc1' -i https://pypi.tuna.tsinghua.edu.cn/simple
+```
+
+:::

+#### 使用 pip 安装
+
+使用以下命令查看 CUDA 和 PyTorch 的版本
+
+```bash
+python -c 'import torch;print(torch.__version__);print(torch.version.cuda)'
+```
+
+根据系统的类型、CUDA 版本、PyTorch 版本以及 MMCV 版本选择相应的安装命令

+[Dockerfile](release/Dockerfile) 默认安装最新的 mmcv，如果你想要指定版本，可以使用下面的命令
 
-```{note}
-mmcv 没有提供 Windows 平台 `cu102-torch1.8.0` 和 `cu92-torch*` 的预编译包。
+```bash
+docker image build -t mmcv -f docker/release/Dockerfile --build-arg MMCV=2.0.0rc1 .
 ```
 
-除了使用预编译包之外，另一种方式是在本地进行编译，直接运行下述命令
+如果你想要使用其他版本的 PyTorch 和 CUDA，你可以在构建镜像时指定它们的版本。
 
-```python
-pip install 'mmcv>=2.0.0rc1'
+例如指定 PyTorch 的版本是 1.11，CUDA 的版本是 11.3
+
+```bash
+docker build -t mmcv -f docker/release/Dockerfile \
+    --build-arg PYTORCH=1.11.0 \
+    --build-arg CUDA=11.3 \
+    --build-arg CUDNN=8 \
+    --build-arg MMCV=2.0.0rc1 .
 ```
 
-但注意本地编译可能会耗时 10 分钟以上。
+更多 PyTorch 和 CUDA 镜像可以点击 [dockerhub/pytorch](https://hub.docker.com/r/pytorch/pytorch/tags) 查看。
 
-b. 安装精简版
+### 安装 mmcv-lite
+
+如果你需要使用和 PyTorch 相关的模块，请确保 PyTorch 已经成功安装在环境中，可以参考 [PyTorch 官方安装文档](https://pytorch.org/get-started/locally/#start-locally)。
 
 ```python
 pip install mmcv-lite
 ```
