在python命令行中输入解析参数作为变量？

Question

I´m trying to input a string variable as a parse argument.

Run the code with following line:

for i in range(0,5):
  para=str(i)+"test.params"
  !python test.py --model I3D_resnet50 --resume-params para
 

The parse argument is added in test.py :

parser.add_argument('--resume-params', type=str, default='default.params',
                        help='path of parameters to load from.')

But the code is not working, even if i add nargs='*' in parse.add_argument . Is it possible that a variable can be input the parse argument?

Answer 1

I have a little script that echos the sys.argv :

In [173]: cat echo.py
import sys
print(sys.argv)

In an ipython session I can call it with:

In [174]: !python3 echo.py test commandline
['echo.py', 'test', 'commandline']

Or using a para variable:

In [175]: para = "test line"
In [176]: !python3 echo.py $para
['echo.py', 'test', 'line']

The sys.argv echo could be replaced with a working argparse parser.
