这段代码的作用是:如果当前文件作为主程序运行,那么会创建一个 argparse.ArgumentParser 对象,用于解析命令行参数。然后会添加一个名为 "--port" 的参数,用于指定端口号,默认为 5000。接着会解析命令行参数,并将结果保存在 args 变量中。最后会加载一个名为 "yolov5s" 的 yolov5 模型,并将其自适应形状。

代码解释:if __name__ == '__main__': parser = argparse.ArgumentParser()
这段代码主要是判断当前脚本是否为主程序,即判断当前脚本是否被直接运行。如果是,则创建一个ArgumentParser对象parser,用于解析命令行参数。ArgumentParser是Python标准库中的一个命令行解析工具,可以方便地解析命令行参数,生成帮助信息等。函数的作用是判断当前脚本是否为主程序,并创建一个ArgumentParser对象。
def get_argparser(): parser = argparse.ArgumentParser()
Sorry, as an AI language model, I don't have access to the previous context or the purpose of the function you shared. But based on the function signature, it seems like this is a Python function that returns an instance of the `ArgumentParser` class from the `argparse` module. The purpose of this class is to create a parser object that can parse command-line arguments and options.
Here's an example usage of the `ArgumentParser` class:
```
import argparse
def get_argparser():
parser = argparse.ArgumentParser()
parser.add_argument('--name', help='Enter your name')
parser.add_argument('--age', type=int, help='Enter your age')
return parser
if __name__ == '__main__':
parser = get_argparser()
args = parser.parse_args()
print(f"Hello {args.name}, you are {args.age} years old!")
```
In the above example, the `get_argparser()` function creates an instance of the `ArgumentParser` class and adds two arguments to it - `name` and `age`. The `parse_args()` method of the parser object is then called to parse the command-line arguments and options. Finally, the values of the `name` and `age` arguments are printed using the `print()` function.
