## 简介 | ||
|
||
MMCV 是一个面向计算机视觉的基础库,它支持了很多开源项目,例如: | ||
|
||
- [MMCV](https://github.com/open-mmlab/mmcv): 计算机视觉基础库 | ||
- [MMClassification](https://github.com/open-mmlab/mmclassification): 图像分类工具箱 | ||
- [MMDetection](https://github.com/open-mmlab/mmdetection): 目标检测工具箱 | ||
- [MMDetection3D](https://github.com/open-mmlab/mmdetection3d): 新一代通用 3D 目标检测平台 | ||
- [MMSegmentation](https://github.com/open-mmlab/mmsegmentation): 语义分割工具箱 | ||
- [MMAction2](https://github.com/open-mmlab/mmaction2): 新一代视频理解工具箱 | ||
- [MMTracking](https://github.com/open-mmlab/mmtracking): 一体化视频目标感知平台 | ||
- [MMPose](https://github.com/open-mmlab/mmpose): 姿态估计工具箱 | ||
- [MMEditing](https://github.com/open-mmlab/mmediting): 图像视频编辑工具箱 | ||
|
||
MMCV 提供了如下众多功能: | ||
|
||
- 通用的 IO 接口 | ||
- 图像和视频处理 | ||
- 图像和标注结果可视化 | ||
- 常用小工具(进度条,计时器等) | ||
- 基于 PyTorch 的通用训练框架 | ||
- 多种 CNN 网络结构 | ||
- 高质量实现的常见 CUDA 算子 | ||
|
||
如想了解更多特性和使用,请参考[文档](http://mmcv.readthedocs.io/en/latest)。 | ||
|
||
提示: MMCV 需要 Python 3.6 以上版本。 | ||
|
||
## 安装 | ||
|
||
MMCV 有两个版本: | ||
|
||
- **mmcv**: 精简版,不包含 CUDA 算子但包含其余所有特性和功能,类似 MMCV 1.0 之前的版本。如果你不需要使用 CUDA 算子的话,精简版可以作为一个考虑选项。 | ||
- **mmcv-full**: 完整版,包含所有的特性以及丰富的开箱即用的 CUDA 算子。注意完整版本可能需要更长时间来编译。 | ||
|
||
**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。 | ||
|
||
a. 安装精简版 | ||
|
||
```python | ||
pip install mmcv | ||
``` | ||
|
||
b. 安装完整版 | ||
|
||
在安装 mmcv-full 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/)。 | ||
|
||
我们提供了不同 PyTorch 和 CUDA 版本的 mmcv-full 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。 | ||
|
||
i. 安装最新版本 | ||
|
||
如下是安装最新版 ``mmcv-full`` 的命令 | ||
|
||
```shell | ||
pip install mmcv-full -f https://download.openmmlab.com/mmcv/dist/{cu_version}/{torch_version}/index.html | ||
``` | ||
|
||
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``、``PyTorch 1.7.0`` 兼容的最新版 ``mmcv-full``,使用如下替换过的命令 | ||
|
||
```shell | ||
pip install mmcv-full -f https://download.openmmlab.com/mmcv/dist/cu110/torch1.7.0/index.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。 | ||
|
||
ii. 安装特定的版本 | ||
|
||
如下是安装特定版本 ``mmcv-full`` 的命令 | ||
|
||
```shell | ||
pip install mmcv-full=={mmcv_version} -f https://download.openmmlab.com/mmcv/dist/{cu_version}/{torch_version}/index.html | ||
``` | ||
|
||
首先请参考版本发布信息找到想要安装的版本号,将 ``{mmcv_version}`` 替换成该版本号,例如 ``1.2.2``。 | ||
然后将链接中的 ``{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``、``PyTorch 1.7.0`` 兼容的 ``mmcv-full`` 1.2.2 版本,使用如下替换过的命令 | ||
|
||
```shell | ||
pip install mmcv-full==1.2.2 -f https://download.openmmlab.com/mmcv/dist/cu110/torch1.7.0/index.html | ||
``` | ||
|
||
对于更多的 PyTorch 和 CUDA 版本组合,请参考下表: | ||

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 | ||
|
||
```python | ||
pip install mmcv-full | ||
``` | ||
|
||
但注意本地编译可能会耗时 10 分钟以上。 | ||
|
||
c. 安装完整版并且编译 onnxruntime 的自定义算子 | ||
|
||
- 详细的指南请查看 [这里](docs/onnxruntime_op.md)。 | ||
