Arg parser error :args = vars(ap.parse_args()) exception occured : python

ap = argparse.ArgumentParser()
ap.add_argument("-i", "--image", required=True,
help="path to input image")
ap.add_argument("-d", "--dataset", required=True,
help="path to dataset")
ap.add_argument("-m", "--model", required=True,
help="path to Caffe pre-trained model")
ap.add_argument("-l", "--labels", required=True,
help="path to ImageNet labels (i.e., syn-sets)")
args = vars(ap.parse_args())
and I'm getting the output as
usage: train.py [-h] -i IMAGE -d DATASET -m MODEL -l LABELS
ipykernel_launcher.py: error: the following arguments are required: -i/--image, -p/--prototxt, -m/--model, -l/--labels.

System Exit: 2

You have this error because you are running your script without passing the required parameters you defined.
You will not have the error if you run the script like this:
script_name.py -i image_path -d data_path -m model_path -l label_path

While Executing code on google colab error regarding the argparse.ArgumentParser()

I am not able to solve this error is it that we cannot use argparse on google colab or there is some alternative to it
The code is:-
if __name__ == "__main__":
parser = argparse.ArgumentParser()
parser.add_argument("-d", "--data", required=True, help="CSV file with quotes to run the model")
parser.add_argument("-m", "--model", required=True, help="Model file to load")
parser.add_argument("-b", "--bars", type=int, default=50, help="Count of bars to feed into the model")
parser.add_argument("-n", "--name", required=True, help="Name to use in output images")
parser.add_argument("--commission", type=float, default=0.1, help="Commission size in percent, default=0.1")
parser.add_argument("--conv", default=False, action="store_true", help="Use convolution model instead of FF")
args = parser.parse_args()
prices = data.load_relative(args.data)
env = environ.StocksEnv({"TEST": prices}, bars_count=args.bars, reset_on_close=False, commission=args.commission,
state_1d=args.conv, random_ofs_on_reset=False, reward_on_close=False, volumes=False)
The Error is :
usage: ipykernel_launcher.py [-h] -d DATA -m MODEL [-b BARS] -n NAME

ipykernel_launcher.py: error: the following arguments are required: -d/--data, -m/--model, -n/--name

Rewrite this code using easydict. Argparse is not working properly

I have the following code :
ap = argparse.ArgumentParser()
ap.add_argument("-i", "--image", type=str,help="path to input image")
ap.add_argument("-east", "--east", type=str,help="path to input EAST text detector")
ap.add_argument("-c", "--min-confidence", type=float, default=0.5,help="minimum probability required to inspect a region")
ap.add_argument("-w", "--width", type=int, default=320,help="resized image width (should be multiple of 32)")
ap.add_argument("-e", "--height", type=int, default=320,help="resized image height (should be multiple of 32)")
args = vars(ap.parse_args())
The problem is that I get the following error :
usage: ipykernel_launcher.py [-h] [-i IMAGE] [-east EAST] [-c MIN_CONFIDENCE]
[-w WIDTH] [-e HEIGHT]
ipykernel_launcher.py: error: unrecognized arguments: -f C:\Users\hp\AppData\Roaming\jupyter\runtime\kernel-e147c702-ba2b-4876-a2d6-01454f32f612.json

Parse command line argument in python

have to do command line parsing and I am getting this error. I'm very new to Python and I don't know what the error means.
ap = argparse.ArgumentParser()
ap.add_argument("-i", "--image", required=True,
help="path to input image")
ap.add_argument("-m", "--mask-rcnn", required=True,
help="base path to mask-rcnn directory")
ap.add_argument("-v", "--visualize", type=int, default=0,
help="whether or not we are going to visualize each instance")
ap.add_argument("-c", "--confidence", type=float, default=0.5,
help="minimum probability to filter weak detections")
ap.add_argument("-t", "--threshold", type=float, default=0.3,
help="minimum threshold for pixel-wise mask segmentation")
args = vars(ap.parse_args())
I am getting this error:
usage: main.py [-h] -i IMAGE -m MASK_RCNN [-v VISUALIZE] [-c CONFIDENCE]

argparse processes the strings in the sys.argv list. Normally this comes from the command line values provided when calling the script containing the argparse code:
$ python main.py -i foo -m bar
But it looks like you are using ipython. It would be good to see how you call this script. But you might need to use:
$ ipython -i main.py -- -i foo -m bar
The '--' separates the input that ipython uses from the input that it should make available to main.py.

How to parse arguments in python (spyder)?

I am following this tutorial and trying to run the below part of the script. I am using python 3.7 and spyder 3.3.4.
ap = argparse.ArgumentParser()
ap.add_argument("-d", "--dataset", required=True,
help="path to input dataset (i.e., directory of images)")
ap.add_argument("-m", "--model", required=True,
help="path to output model")
ap.add_argument("-l", "--labelbin", required=True,
help="path to output label binarizer")
ap.add_argument("-p", "--plot", type=str, default="plot.png",
help="path to output accuracy/loss plot")
args = vars(ap.parse_args())
I have tried going to Run > Configuration per file and entering the arguments as advised by this post and and this post.
command line options: path1, path2, path3, path4
I filled out the appropriate paths for the arguments above and then ran the script, but go the error below.
usage: train.py [-h] -d DATASET -m MODEL -l LABELBIN [-p PLOT]
train.py: error: the following arguments are required: -d/--dataset,
-m/--model, -l/--labelbin An exception has occurred, use %tb to see the full traceback.
SystemExit: 2
How can I fix this error to run my script appropriately and pass the arguments in spyder?

You can parse arguments by doing a special run from the settings and putting in the order that the arguments are expected.
