It is possible to import multiple modules by separating them with a comma. Then we do some basic error checking to determine that our argument list from ARGV is at least three elements long. The name of the script you are running is always in sys.argv[0]. In this script, our other ...
parser.add_argument方法的type参数理论上可以是任何合法的类型, 但有些参数传入格式比较麻烦,例如list,所以一般使用bool, int, str, float这些基本类型就行了,更复杂的需求可以通过str传入,然后手动解析。bool类型的解析比较特殊,传入任何值都会被解析成True,传入空值时才为False python script.py --bool-val=0#arg...
需要注意的是,脚本运行命令python script.py -gpus=0,1,2 --batch-size=10中的--batch-size会被自动解析成batch_size. parser.add_argument方法的type参数理论上可以是任何合法的类型, 但有些参数传入格式比较麻烦,例如list,所以一般使用bool,int,str,float这些基本类型就行了,更复杂的需求可以通过str传入,然后...
