pycharm中训练卷积神经网络时报错

[weixin_44444428]

报错：
usage: train.py [-h] -dtest DATASET_TEST -dtrain DATASET_TRAIN -m MODEL
[-p PLOT]
train.py: error: the following arguments are required: -dtest/--dataset_test, -dtrain/--dataset_train, -m/--model

我的程序：
def args_parse():
# construct the argument parse and parse the arguments
ap = argparse.ArgumentParser()
ap.add_argument("-dtest", "--dataset_test", required=True,default='../test',
help="path to input dataset_test")
ap.add_argument("-dtrain", "--dataset_train", required=True,default='../train',
help="path to input dataset_train")
ap.add_argument("-m", "--model", required=True,default='traffic_sign.model',
help="path to output model")
ap.add_argument("-p", "--plot", type=str, default="plot.png",
help="path to output accuracy/loss plot")
args = vars(ap.parse_args())
return args

"-dtest", ……这里都改成--dtest ，变成两个横线
