## 安装 MMCV
|
|

2021-07-20 17:18:28 +08:00
|
|
|
|
MMCV 有两个版本:
|
|
|
|
|
|
|
|
|
|
- **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。
|
|
|
|
|
- **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。
|
|
|
|
|
|
|
|
|
|
**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-full`。
|
|
|
|
|
|
|
|
|
|
a. 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 11.1``、``PyTorch 1.9.0`` 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/cu111/torch1.9.0/index.html
|
|
|
|
|
```
|
|
|
|
|
|

|
|
|
|
```{tip}
|
|
|
|
|
PyTorch 在 1.x.0 和 1.x.1 之间通常是兼容的,故 mmcv-full 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-full。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-full。
|
|
|
|
|
|
|
|
|
|
`pip install mmcv-full -f https://download.openmmlab.com/mmcv/dist/cu111/torch1.8.0/index.html`
|
|
|
|
|
```
|
|
|
|
|
|
2021-07-20 17:18:28 +08:00
|
|
|
|
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 ``1.3.9``。
|
|
|
|
|
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 11.1``、``PyTorch 1.9.0`` 兼容的 ``mmcv-full`` 1.3.9 版本,使用如下替换过的命令
|
|
|
|
|
|
|
|
|
|
```shell
|
|
|
|
|
pip install mmcv-full==1.3.9 -f https://download.openmmlab.com/mmcv/dist/cu111/torch1.9.0/index.html
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|

|
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。
|
|
|
|
|
|
|
|
|
|
b. 安装精简版
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
pip install mmcv
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
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](https://mmcv.readthedocs.io/zh_CN/latest/deployment/onnxruntime_custom_ops.html)。
|
|
|
|
|
|
|
|
|
|
如果想从源码编译 MMCV,请参考[该文档](https://mmcv.readthedocs.io/zh_CN/latest/get_started/build.html)。
