Windows10配置SlowFast环境全过程 并使用自己的视频进行demo检测

• 环境简介
• 1. 开始配置
• 2.配置demo环境
• 3. 测试结果

环境简介

pycharm
python=3.7.11

我就是不用linux，就要用window10配置。
你还需要安装git，下下来以后一直下一步即可。
可能还需要Visual Studio。

1. 开始配置

首先下载官网的代码库

git clone https://github.com/facebookresearch/slowfast
cd SlowFast

然后新建一个虚拟环境。

然后自己安装 pytorch 和 torchvision 对应cuda的GPU版本。

接下来就按我给的安装提示一步一步的安装。

# 要双引号！！！！！！！
pip install 'git+https://github.com/facebookresearch/fvcore'  
pip install 'git+https://github.com/facebookresearch/fairscale' 
pip install simplejson
pip install -U iopath
pip install psutil,tensorboard,opencv-python,moviepy,moviepy,pytorchvideo
pip install pillow,pyyaml,pandas,matplotlib,sklearn

其中Detection2的安装可以按这个：

git clone https://github.com/facebookresearch/detectron2.git
python -m pip install -e detectron2

千万要有耐心，一步一步走。

接下来就是就是编译：

python setup.py build develop

如果没报错的话就代表没有错误，如果报错了就代表有错误（听君一席话，，，），即使评论错误提示。

2.配置demo环境

终于到了测试自己视频的环节。
在主目录下/demo/AVA下新建ava.json，复制下面的标签到里面。

ava.json

{"bend/bow (at the waist)": 0, "crawl": 1, "crouch/kneel": 2, "dance": 3, "fall down": 4, "get up": 5, "jump/leap": 6, "lie/sleep": 7, "martial art": 8, "run/jog": 9, "sit": 10, "stand": 11, "swim": 12, "walk": 13, "answer phone": 14, "brush teeth": 15, "carry/hold (an object)": 16, "catch (an object)": 17, "chop": 18, "climb (e.g., a mountain)": 19, "clink glass": 20, "close (e.g., a door, a box)": 21, "cook": 22, "cut": 23, "dig": 24, "dress/put on clothing": 25, "drink": 26, "drive (e.g., a car, a truck)": 27, "eat": 28, "enter": 29, "exit": 30, "extract": 31, "fishing": 32, "hit (an object)": 33, "kick (an object)": 34, "lift/pick up": 35, "listen (e.g., to music)": 36, "open (e.g., a window, a car door)": 37, "paint": 38, "play board game": 39, "play musical instrument": 40, "play with pets": 41, "point to (an object)": 42, "press": 43, "pull (an object)": 44, "push (an object)": 45, "put down": 46, "read": 47, "ride (e.g., a bike, a car, a horse)": 48, "row boat": 49, "sail boat": 50, "shoot": 51, "shovel": 52, "smoke": 53, "stir": 54, "take a photo": 55, "text on/look at a cellphone": 56, "throw": 57, "touch (an object)": 58, "turn (e.g., a screwdriver)": 59, "watch (e.g., TV)": 60, "work on a computer": 61, "write": 62, "fight/hit (a person)": 63, "give/serve (an object) to (a person)": 64, "grab (a person)": 65, "hand clap": 66, "hand shake": 67, "hand wave": 68, "hug (a person)": 69, "kick (a person)": 70, "kiss (a person)": 71, "lift (a person)": 72, "listen to (a person)": 73, "play with kids": 74, "push (another person)": 75, "sing to (e.g., self, a person, a group)": 76, "take (an object) from (a person)": 77, "talk to (e.g., self, a person, a group)": 78, "watch (a person)": 79}

然后下载官网权重文件

打开/demo/AVA/SLOWFAST_32x2_R101_50_50.yaml将我的配置信息粘贴进去

注意修改，权重文件的路径，label文件的路径，输入视频的路径以及输出视频的路径

3. 测试结果

这样就代表demo运行成功。

结果展示
